Agfa started that series in the early 1970ies, the new identifier of all models was the red-orange dot as shutter button, a feature Agfa used successfully for all following cameras. The name "Sensor" refers to that shutter button, the new design should guarantee a very soft and shake-free release.
All models share basically the same body, which includes another characteristic feature: with the film advance lever at the bottom also the exposed film has to be rewound. Furthermore the exposed frames have an extra container in the film chamber, so they are protected when the door is opened accidentally.
Other shared characteristics are a manual focus lens with the minimum focus distance of 1 m, an f-stop range from f/2.8 to f/22 and the lack of a filter thread. All models have an exposure meter, a bright frame viewfinder with parallax marks, a cable release thread (due to the red button it's on the back), a hot shoe, a tripod bush and a frame counter at the bottom, which has to be reset manually.
In the mid 70ies these cameras were replaced by the very compact Optima Sensor Electronic models, which kept some features like the peculiar rewind mechanism.
The models in detail:
The Silette LK is clearly the budget model, fully manual and fully mechanical (no battery required), 3-element 2.8/45 Color-Agnar lens in Parator shutter, unlike the other models the lens barrel is plastic made. Shutter speeds from 1/30 to 1/300 s and B, coupled exposure meter with Selenium cell whose needle is visible in the viewer and on top, ISO range from 25 to 400.
Optima 200: 3-element 2.8/42 Color-Apotar lens in Paratic shutter, zone focusing. Like all previous Agfa Optima cameras the Optima 200 has a programmed automatic exposure, in the viewfinder a red/green signal displays sufficient light. Shutter speeds from 1/30 to 1/200 s. A Selenium cell is used, so the camera also doesn't require a battery, ISO range (of the variant here) 25 to 160. If a flash is mounted in the hot shoe, the camera uses 1/30 s and switches into flash-matic mode, guide number (m) from 11 to 27.
Optima 500: like the Optima 200, but with a CdS-cell for the exposure meter instead of a Selenium cell, so a 625 PX battery is required. ISO range from 25 to 400, shutter speeds from 1/30 to 1/500 s. Furthermore the shutter features a B-setting with the full f-stop range. Afaik the Optima 500 was the only model which was available in black and silver.
Selectronic: 3-element 2.8/45 Color-Apotar lens in Paratronic shutter. Aperture priority automatic exposure mode, the f-stop ring has no click-stops. Both F-stop and shutter speed (1/500 to 1/30 s, symbol for slower speeds) are displayed in the viewfinder. Slowest shutter speed up to 15 s. CdS-cell (behind the right one of the two eyes), two 625 PX batteries are required, ISO range from 25 to 400. Behind the left eye is a light bulb, it is lit when the shutter is open, it also indicates full batteries when the test button is pressed.
Self-timer, no B-setting, no flash-matic mode.
Price about DM 350,-
Selectronic S, the top model. Like the Selectronic, but with 4-element 2.8/45 Color-Solinar lens and rangefinder.

'STREET ART/GRAFFITI SHEFFIELD' - TAKEN ON A PANASONIC LUMIZ DMC-FX12 CCD SENSOR COMPACT CAMERA - NOVEMBER 2024
UPDATE April 29, 2011 - added Nikon D5100
A friend of mine just got the new Nikon D5100 and I couldn't resist to do the Diet Coke test :)
The camera has the same sensor as the D7000 and can produce exactly the same images and high ISO all away up to 25600 ISO... pretty impressive for such a small camera. If I was in the market for a DSLR right now, the D5100 would be my choice for over any other consumer DSLR regardless the brand.
November 22, 2010 - added Nikon D80.
Karl Zimmerman sent me an image taken with a Nikon D80, but with regular Coke, not Diet Coke. He couldn't find any where he lives!. It seems people in Taiwan doesn't have overweight problems like in the U.S. :) Thank you Karl!
The rest is from the original post:
My Flickr friend digital-analog got recently a used Nikon D100 and he wanted me to do a test. He took a picture of a Diet Coke can at 6400 ISO and he asked me to do the same thing with the D7000 to compare images.
Some people were interested in doing this test too, so I'll be adding new pictures with different cameras.
All the images are taken as JPEG standard settings at f/6.3 and 6400 ISO at about 55mm. The shutter speed is different since the light conditions are different for each case.
All images are downscaled to 3008x2000 pixels, maximum size of the D100.
The order of the cameras is not important. It's just to make easier people to find them.

El sensor que está en segundo plano es inductivo y detecta cuando el piñón de ataque del prelanzador está en reposo (LED verde) y cuando está accionado (LED rojo). Este único LED está encima del panel de instrumentos al lado del cuenta revoluciones del rotor y se ilumina en verde o rojo según el sensor detecta o no el piñón de ataque. Es un elemento que nos indica que una vez prelanzado, el piñón a descendido completamente y se puede iniciar el despegue al pasar de color rojo a color verde.
CCD Sesnor - it is definitely different rendering to CMOS. I really do like this sensor and camera. It's the last CCD nikon sensor made in 2009 10 mpxls. Cost used $120 AUD ($80 USD)

Today I decided to take the opportunity to use a Sony NEX-7 [Crop-Sensor] with a Sony-Zeiss Full-Frame 35mm 1.4f lens.
I have recently read that using a full-frame lens with a crop sensor may not produce better results than using a lens designed from a crop-sensor camera and in fact the images will be less shary.
When starting out, many photographers choose to go with a crop body and invest in full frame lenses. This is usually recommended as a good approach as you can keep your lenses and swap out your body for something newer down the road, eventually leading to that high quality full frame sensor that you always wanted. However some experts, especially Tony Northrup, claim that starting out with the full frame lens and crop bodies does not provide you with the sharp images.
In my case I had a top end full frame camera [Canon 1DSIII] with a set of very expensive glass and I was not at all happy as the combination was way too heavy and totally unsuitable for street photography. About five years ago I decided that I needed a better solution and after using a Sony NEX-5 for about a year I decided to purchase a NEX-7 and switch from DSLR to Mirrorless [at the time that was a big gamble]. In theory it would be possible to use my Canon lenses with the NEX-7 but in reality it was not a workable solution. The NEX-7 featured a crop-sensor so I purchased a set of suitable Sony lenses and they were not expensive.
My reason for getting the NEX-7 and associated lenses was greatly reduced weight coupled with the fact that my equipment did not attract unwelcome attention.
The NEX-7 performed way beyond my expectations and I was really pleased and then towards the end of last year because the camera was giving problems at random I threw all logic out the window and took an ever bigger gamble by purchasing a Sony A7RMkII full frame mirrorless camera which is larger and heavier than the NEX-7.
To be honest, there is no comparison between the two cameras, the A7R is very much superior and while it is heavier it is actually easier to use. Also the Canon lenses actually work with the A7R but using the necessary adaptor was a pain and added weight. However the Canon lenses showed what the A7RMkII could do so I decided that maybe I should consider getting some native Sony FE prime lenses and then I discovered that they all were expensive and heavy [ unless I got manual focus lens such as the Loxia ]. Anyway I ended up with a set of primes [and no cash] but I now have serious weight issue especially when I travel.
I was planning to use the NEX-7 as a backup or when I travel but the crop-lenses are not very good so it would make no sense to leave my full-frame lenses behind so a possible solution would to bring along one of the FE primes [35mm 1.4f] but then I came across discussions online claiming that FE lenses underperform when used with a crop-sensor. Of course there is another issue in that the NEX-7 is at the end of its life and needs to be replaced by something like the A6300 but as I already said I have no spare cash.
Over the next few weeks of February and March 2020, I made lots of trips to the VA hospital to see my doctor, my cardiologist, and more testing gear. I had ultrasound and CT scans of my heart followed by consultations on what they saw. They say that surgery will probably not be necessary but prescribed more meds. My doctor decided to get me a heart monitor to wear for several weeks. They showed me how to apply the sensors, hook up and turn on the gear, and take it off for wet personal hygiene and showers.
There are four sensors that are placed in specific places that are wired to a small RF transmitter on a lanyard around my neck. The transmitter talks to a modified cell phone that has to be within ten feet or so and sends the data to a medical monitoring station near Chicago. A couple of times a tech called me up to ask why my heartrate was up. The first time was probably due to a stubborn shit that needed urging. The second time I felt nothing and had no explanation. Ultimately, the three week test proved that I did have occasional rapid heartrate episodes at random times.
Besides having to take time to unhook every time I needed to get cleaned up and then hook up again, I had to keep the monitor phone at my bedside, in my purse, on a belt holster, or on the kitchen countertop, dinner table, vanity table, etc. If you click to magnify the photo, you can see icons on the phone that match white, red, green, or black sensor locations.
I was issued the monitor set in March just before the COVID lockdown. I remember hearing BBC reports of a mysterious virus in China during the Christmas 2019 holidays. By January the epidemic was in full swing in China, but the US was paralyzed in its response due to incompetence by Trumputin. I wondered how my VA hospital was going to react to what was obviously a pandemic that would strike Houston.
During my first morning in the hospital, I complimented the guy cleaning my room. I told him I noticed how clean everything was, and that his job would soon be part of a life or death situation. I said I spent as much time in the Army with a broom, mop, and toilet brush as with a rifle and machinegun. He was an Army vet, too and laughed. I said the Army makes a fetish out of cleanliness because in most wars, disease kills more people than battle. I wished him luck because I knew that in a few weeks, lots of patients would be dying, and he would have to clean up after them. I was right.
Harris County has lost more than 8900 people to COVID. Texas has lost more than 69,000 people mostly due to Governor Abbott's bungling and interference with local officials trying to enact public health measures like masking in public places. That's more than we lost in the Vietnam War and all of our useless oil wars in the Middle East combined. Nationwide, the US has lost more than 732,000 deaths due to the Trumputin Covfefe Virus pandemic because Trump and his fellow RepUGLUcan idiots didn't believe in science and wanted to kill as many poor and non-white people in the cities as possible. It is evident that "conservatism" is simply another word for BACKWARDNESS because they oppose all public health measure like mask mandates, prohibitions against indoor crowds, and mandatory vaccinations that could have controlled this disease many months ago.

MOC: Sensor GTR. A variation of the theme from my previous Supercar - I wanted to see if I could build something a supercar that looked a bit more like it was meant for the road than for the track. Very happy with the result.
The original SiAra beacon was established as a long range sensor/communication relay beacon. It was infamous as the point of first contact and was subsequently destroyed in the First Interstellar war.
Its replacement, the first SiAra station was a military outpost on the edge of Colonial territory and was the site of diplomatic events and as well as acting as a first line of a Colonial defence.
Today, the SiAra station still maintains a small fleet garrison, but mainly acts as a commerce center allowing ships of all sizes from all sectors to dock and conduct business. Besides being a convenient resupply depot, It is also responsible for search and rescue operations and assisting ships in distress.

Littorio was the lead ship of her class of battleship; she served in the Italian Regia Marina (Royal Navy) during World War II. She was named after the Lictor ("Littorio" in Italian), in ancient times the bearer of the Roman fasces, which was adopted as the symbol of Italian Fascism. Littorio and her sister Vittorio Veneto were built in response to the French battleships Dunkerque and Strasbourg. They were Italy's first modern battleships, and the first 35,000-ton capital ships of any nation to be laid down under the terms of the Washington Naval Treaty. Littorio was laid down in October 1934, launched in August 1937, and completed in May 1940.
Shortly after her commissioning, Littorio was badly damaged during the British air raid on Taranto on 11 November 1940, which put her out of action until the following March. Littorio thereafter took part in several sorties to catch the British Mediterranean Fleet, most of which failed to result in any action, the notable exception being the Second Battle of Sirte in March 1942, where she damaged several British warships. Littorio was renamed Italia in July 1943 after the fall of the Fascist government. On 9 September 1943, the Italian fleet was attacked by German bombers while it was on its way to internment. During this action, which saw the destruction of her sister Roma, Italia herself was hit by a Fritz X radio-controlled bomb, causing significant damage to her bow. As part of the armistice agreement, Italia was interned at Malta, Alexandria, and finally in the Great Bitter Lake in the Suez Canal, where she remained until 1947. Italia was awarded to the United States as a war prize and scrapped at La Spezia in 1952–54.
Littorio and her sister Vittorio Veneto were designed in response to the French Dunkerque-class battleships.[2] Littorio was 237.76 meters (780.1 ft) long overall, had a beam of 32.82 m (107.7 ft) and a draft of 9.6 m (31 ft). She was designed with a standard displacement of 40,724 long tons (41,377 t), a violation of the 35,000-long-ton (36,000 t) restriction of the Washington Naval Treaty; at full combat loading, she displaced 45,236 long tons (45,962 t). The ship was powered by four Belluzo geared steam turbines rated at 128,000 shaft horsepower (95,000 kW). Steam was provided by eight oil-fired Yarrow boilers. The engines provided a top speed of 30 knots (56 km/h; 35 mph) and a range of 3,920 mi (6,310 km; 3,410 nmi) at 20 kn (37 km/h; 23 mph). Littorio had a crew of 1,830 to 1,950 over the course of her career.[3][4]
Littorio's main armament consisted of nine 381-millimeter (15.0 in) 50-caliber Model 1934 guns in three triple turrets; two turrets were placed forward in a superfiring arrangement and the third was located aft. Her secondary anti-surface armament consisted of twelve 152 mm (6.0 in) /55 Model 1934/35 guns in four triple turrets placed at the corners of the superstructure. These were supplemented by four 120 mm (4.7 in) /40 Model 1891/92 guns in single mounts; these guns were old weapons and were primarily intended to fire star shells. Littorio was equipped with an anti-aircraft battery that comprised twelve 90 mm (3.5 in) /50 Model 1938 guns in single mounts, twenty 37 mm (1.5 in)/54 /54 guns in eight twin and four single mounts, and sixteen 20 mm (0.79 in) /65 guns in eight twin mounts.[5] A further twelve 20 mm guns in twin mounts were installed in 1942. She received an EC 3 bis radar set in August 1941, an updated version in April 1942—which proved to be unsuccessful in service—and finally the EC 3 ter model in September 1942.[6]
The ship was protected by a main armored belt that was 280 mm (11 in) thick with a second layer of steel that was 70 mm (2.8 in) thick. The main deck was 162 mm (6.4 in) thick in the central area of the ship and reduced to 45 mm (1.8 in) in less critical areas. The main battery turrets were 350 mm (14 in) thick and the lower turret structure was housed in barbettes that were also 350 mm thick. The secondary turrets had 280 mm thick faces and the conning tower had 260 mm (10 in) thick sides.[4] Littorio was fitted with a catapult on her stern and equipped with three IMAM Ro.43 reconnaissance float planes or Reggiane Re.2000 fighters.[7]
Service history
Littorio was laid down at the Ansaldo shipyards in Genoa on 28 October 1934 to commemorate the Fascist Party's March on Rome in 1922. Her sister Vittorio Veneto was laid down the same day.[8] Changes to the design and a lack of armor plating led to delays in the building schedule, causing a three-month slip in the launch date from the original plan of May 1937. Littorio was launched on 22 August 1937, during a ceremony attended by many Italian dignitaries. She was sponsored by Signora Teresa Ballerino Cabella, the wife on an Ansaldo employee.[9] After her launch, the fitting out period lasted until early 1940. During this time, Littorio's bow was modified to lessen vibration and reduce wetness over the bow. Littorio ran a series of sea trials over a period of two months between 23 October 1939 and 21 December 1939. She was commissioned on 6 May 1940, and after running additional trials that month, she transferred to Taranto where she—along with Vittorio Veneto—joined the 9th Division under the command of Rear Admiral Carlo Bergamini.[10]
On 31 August – 2 September 1940, Littorio sortied as part of an Italian force of five battleships, ten cruisers, and thirty-four destroyers to intercept British naval forces taking part in Operation Hats and Convoy MB.3, but contact was not made with either group due to poor reconnaissance and no action occurred.[6][11] A similar outcome resulted from the movement against British Operation "MB.5" on 29 September - 1 October; Littorio, four other battleships, eleven cruisers, and twenty-three destroyers had attempted to intercept the convoy carrying troops to Malta.[6][12]
On the night of 10–11 November, the British Mediterranean Fleet launched an air raid on the harbor in Taranto. Twenty-one Swordfish torpedo bombers launched from the aircraft carrier HMS Illustrious attacked the Italian fleet in two waves.[13] The Italian base was defended by twenty-one 90 mm anti-aircraft guns and dozens of smaller 37 mm and 20 mm guns, along with twenty-seven barrage balloons. The defenders did not possess radar, however, and so were caught by surprise when the Swordfish arrived. Littorio and the other battleships were also not provided with sufficient anti-torpedo nets. The first wave struck at 20:35, followed by the second about an hour later.[14]
Damaged Littorio
The planes scored three hits on Littorio, one hit on Caio Duilio, and one on Conte di Cavour.[13] Of the torpedoes that struck Littorio, two hit in the bow and one struck the stern; the stern hit destroyed the rudder and shock from the explosion damaged the ship's steering gear. The two forward hits caused major flooding and led her to settle by the bows, with her decks awash up to her main battery turrets. She could not be brought into dock until 11 December due to a fourth, unexploded torpedo discovered under her keel; removing the torpedo proved to be a painstaking task, as any shift in the magnetic field around the torpedo might detonate its magnetic detonator.[15] Repairs lasted until 11 March 1941.[16]
Convoy operations
After repairs were completed, Littorio participated in an unsuccessful sortie to intercept British forces on 22–25 August. A month later, she led the attack on the Allied convoy in Operation Halberd on 27 September 1941.[16] The British force escorting the convoy included the battleships Rodney, Nelson, and Prince of Wales; Italian reconnaissance reported the presence of a powerful escort, and the Italian commander, under orders not to engage unless he possessed a strong numerical superiority, broke off the operation and returned to port.[17] On 13 December, she participated in another sweep to catch a convoy to Malta, but the attempt was broken off after Vittorio Veneto was torpedoed by a British submarine. Three days later, she steamed out to escort Operation M42, a supply convoy to Italian and German forces in North Africa.[16] By late 1941, British success at breaking the Enigma code made it increasingly difficult for Axis convoys to reach North Africa. The Italians therefore committed their battle fleet to the convoy effort to better protect the transports.[17] The next day, she took part in the First Battle of Sirte. Littorio, along with the rest of the distant covering force, engaged the escort of a British convoy heading for Malta that happened to run into the M42 convoy late in the day.[16] Littorio opened fire at extreme range, around 35,000 yards (32,000 m), but she scored no hits. Nevertheless, the heavy Italian fire forced the British force to withdraw under cover of a smokescreen and the M42 convoy reached North Africa without damage.[18][19]
On 3 January 1942, Littorio was again tasked with convoy escort, in support of Operation M43; she was back in port by 6 January. On 22 March, she participated in the Second Battle of Sirte, as the flagship for an Italian force attempting to destroy a British convoy bound for Malta.[16] After the fall of darkness, several British destroyers made a close-range attack on Littorio, but heavy fire from her main and secondary guns forced the destroyers to retreat.[20] As the destroyers withdrew, one of them hit Littorio with a single 4.7-inch (120 mm) shell, which caused minor damage to the ship's fantail.[21] During the battle, Littorio hit and seriously damaged the destroyers HMS Havock and Kingston. She also hit the cruiser Euryalus but did not inflict significant damage. Kingston limped to Malta for repairs, where she was later destroyed during an airstrike while in drydock.[22] Muzzle blast from Littorio's rear turret set one of her floatplanes on fire, though no serious damage to the ship resulted.[20] She fired a total of 181 shells from her main battery in the course of the engagement. Though the Italian fleet was unable to directly attack the convoy, it forced the transports to scatter and many were sunk the next day by air attack.[23]
Three months later, on 14 June, Littorio participated in the interception of the Operation Vigorous convoy to Malta from Alexandria. Littorio, Vittorio Veneto, four cruisers and twelve destroyers were sent to attack the convoy.[24] The British quickly located the approaching Italian fleet and launched several night air strikes in an attempt to prevent them from reaching the convoy, though the aircraft scored no hits.[25] While searching for the convoy the next day, Littorio was hit by a bomb dropped by a B-24 Liberator; the bomb hit the roof of turret no. 1 but caused negligible damage to the rangefinder hood and barbette, along with splinter damage to the deck. The turret nevertheless remained serviceable and Littorio remained with the fleet. The threat from Littorio and Vittorio Veneto forced the British convoy to abort the mission.[24][26] At 14:00, the Italians broke off the chase and returned to port; shortly before midnight that evening, Littorio was struck by a torpedo dropped by a British Wellington bomber, causing some 1,500 long tons (1,500 t) of water to flood the ship's bow. Her crew counter-flooded 350 long tons (360 t) of water to correct the list.[27] The ship was able to return to port for repairs, that lasted until 27 August.[27][24][26] She remained in Taranto until 12 December, when the fleet was moved to La Spezia.[26]
Fate
Littorio was inactive for the first six months of 1943 due to severe fuel shortages in the Italian Navy.[28] Only enough fuel was available for Littorio, Vittorio Veneto and their recently commissioned sister Roma, but even then the fuel was only enough for emergencies.[29] On 19 June 1943, an American bombing raid targeted the harbor at La Spezia and hit Littorio with three bombs. She was renamed Italia on 30 July after the government of Benito Mussolini fell from power. On 3 September, Italy signed an armistice with the Allies, ending her active participation in World War II. Six days later, Italia and the rest of the Italian fleet sailed for Malta, where they would be interned for the remainder of the war. While en route, the German Luftwaffe (Air Force) attacked the Italian fleet using Dornier Do 217s armed with Fritz X radio-controlled bombs. One Fritz X hit Italia just forward of turret no. 1; it passed through the ship and exited the hull, exploding in the water beneath and causing serious damage. Roma was meanwhile sunk in the attack.[26][30]
Italia and Vittorio Veneto were then moved, first to Alexandria, Egypt, and then to the Great Bitter Lake in the Suez Canal in Egypt on 14 September; they remained there until the end of the war. On 5 February 1947, Italia was finally permitted to return to Italy. In the Treaty of Peace with Italy, signed five days later on 10 February, Italia was allocated as a war prize to the United States. She was stricken from the naval register on 1 June 1948 and broken up for scrap at La Spezia.[31]

So after talking a bunch of smack about cameras that didn't have interchangeable lenses, I ended up getting one myself. Believe me, this came out of pure necessity. I wasn't willing to lug around my D90 to certain places due to its size, but at the same time I didn't want to sacrifice image quality by getting a camera with a smaller sensor. The solution: Nikon's AA filter-less, point-and-shoot-sized camera with a DX sensor and 18.5mm prime lens.
Manufactured by Agfa Kamerawerk AG, Munich, West Germany
Model: c.1970, (all models of Silette produced between 1953-1974)
Agfa logo on the front of the camera: black relief
35 mm film Viewfinder camera
Lens:Agfa Color - Agnar 45mm f/2.8
Aperture: f/2.8 -f /22 , stepless allowing for easy adjustment with the TTL meter
setting: ring and scale on the back of the lens
Focusing: front ring manual focus, w/ DOF scale
Focus range: 1-5m +inf.
Shutter: Parator speeds: 30, 60, 125, 300 +B, extremely quiet
setting : ring and scale on the lens
Shutter release: Red "Sensor" shutter release button,
very smooth and sensitive so no camera shake
Cable release socket: on the back of the top plate
Exposure meter: TTL (coupled to the lens) Selenium Optima 200 Sensor (working !.)
Exposure setting: via 1- the small needle window on the top plate, 2- the indicator in the viewfinder, set the speed and turn the aperture ring
Film speed range: ASA 25-400 (DIN 15-27), setting knob and scales on the lens
View finder: bright frame finder,
Cocking lever: also winds the film, short stroke, on the left of the bottom plate
Frame counter: advance type, manual reset by a button behind the counter window, on the bottom plate
Re-wind release and re-winding: the black lever marked R and arrow on the right lower side of the lens releases and engages the reversing gear
thus the cocking and winding lever is the re-wind lever now

The Silette series' rangefinder models were called Super Silette. There was also an interchangeable lens rangefinder model called the Ambi Silette.
Sensors get dirty, it is impossible to change lens and keep them clean...
Mine has to be cleaned two times a year or more.
When you choose smaller apertures, the dirt spots show shamelessly. In one of my last photos, www.flickr.com/photos/henrique_silva/6600173785/, the aperture was f/36 and so every little tiny bit of dirt was showing, I spent a little time in Lightroom cleaning them, but there are still some in the picture... It was urgent to clean the 40D's sensor
Again I went trough this delicate process, I use Sensor Scope from Delkin Devices, it works well, it uses a combination of vacuum cleaner and moistened sensor wands to get the job done. Here is a before / after mosaic, it is not completly clean, but in fact there is a compromise between having the sensor damaged or have one or two dust spots...
If you want to know more about the process, I will be happy to answer!
Check your sensor for dust!
a - Create a new image in Photoshop or any other application and fill it with white
b - Set your camera to Aperture Priority, ISO100, and aperture to it's minimum f/22 - f/45
c - Set lens focus to Manual, and focus to closest possible
d - Shoot in raw or if in jpeg, turn off special image processing functions
e - Zoom in until the photoshop image fills your camera focusing screen
f - Shoot camera facing the white image on your monitor, and during this exposure, move your camera back and fourth being careful to not to point the lens outside of your white image. You can also zoom in in the image...
g - Process your image, adjust contrast, brightness, clarity, whatever, so that you get a clear view of the dirt spots!
h - Now you can go through the cleaning process - remember that what shows on the bottom of the image will be towards the top of the camera sensor...
i - Repeat the process from a to g and if you are happy with the result, then you are done; otherwise, repeat again... this time I had to make three swab cleanings. It is preferable to clean gently several times than applying to much force.

The universe itself is God and the universal outpouring of its soul. --Chrysippus (Quoted by Cicero in De Natura Deorum)
Season of mists and mellow fruitfulness
Close bosom-friend of the maturing sun
Conspiring with him how to load and bless
With fruit the vines that round the thatch-eves run;
To bend with apples the moss'd cottage-trees,
And fill all fruit with ripeness to the core;
To swell the gourd, and plump the hazel shells
With a sweet kernel; to set budding more,
And still more, later flowers for the bees,
Until they think warm days will never cease,
For Summer has o'er-brimm'd their clammy cells. --To Autumn. by John Keats

"Magic Wire" is so called because of detecting proximity to antenna.
THE MAGIC WIRE
As shown in the diagram, the input tube is a type 6R7 duo-diode triode. The triode section forms the oscillator, in conjunction with the coil L1 which is center-tapped to the cathode. When the triode section is oscillating, the r.f. voltage developed from cathode to ground is impressed on the diode section, causing current to flow through R2 and making the diode plates negative with respect to ground. The control grid of the 25L6 power tube is connected to the diode plates of the 6R7 and consequently a negative bias is placed on the grid which reduces its plate current to a very low value. As soon as the triode ceases to oscillate, there is no longer any r.f. voltage applied to the diodes, the voltage drops and the 25L6 draws high plate current, causing the relay to operate.
It will be noted that no rectifier tube or filler circuit is required in this design, yet the instrument functions on either a.c. or d.c. On a.c., the 6R7 oscillations and the 25L6 draws plate current only on the positive half-cycles. This principle effects a considerable saving in construction cost and in the size of the instrument.
After the parts required have been obtained, the first step in building the unit is to make the chassis, which consists simply of a piece of 16-gauge aluminum or steel bent and drilled in accordance with the plan shown. The front panel, which is included with the standard 6 by 6 cabinet, is drilled and a hole and grommet are placed in the rear panel. The oscillator coil is made by winding 100 turns of No.28 d.c.c. wire on a one-inch bakelite tube 3-1/4 inches long. A tap is brought out at the center of the winding. When the winding has been completed, the entire coil is dipped in a hot half-and-half mixture of beeswax and paraffin to keep the winding in place and exclude moisture. The sensitivity of the outfit is largely dependent upon the efficiency of the coil, so it should be carefully made. C1 is mounted on a small piece of 1/8-inch bakelite, because it must be insulated from the panel.
Wire the chassis first, starting with the heater circuits. Do not connect in the power cord until all wiring has been completed. The shield of the 25L6 is connected to its cathode, the shield of the 6E7 to the heater terminal which goes directly to the line. When all the main wiring has been completed, bring the power cord through the rear panel hole, and solder the three terminals to the terminal strip. The antenna wire is brought in through a rubber-grommeted hole in the top of the cabinet and connected to the stator or plate terminal of C1. A knot in the wire will relieve any strain on this connection. Stranded wire is preferred for the antenna.
The capacitances of C1 and C2 are largely dependent upon the length of antenna wire desired. If only 4 or 5 feet are required, C2 may be omitted. On the other hand, if the wire exceeds 15 feet, C2 will have to be larger than the value given. If the capacitance of C1 were made large (say 150 mmf. or more), C2 could of course be omitted but then the adjustment would become too critical.
The relay employed is a 3,000-ohm plug-in type of standard manufacture. It is a double-pole model and will handle a non-inductive load of 100 watts. It is somewhat more sensitive than is required and any other good relay of 1,000 ohms or more resistance should be suitable. The capacitor, C4, is shunted across the relay coil to prevent chattering. It may be advisable, in some cases, to put a 0.1 mf. paper capacitor across the relay contacts to stop sparking on heavy loads. It is better practice, however, to use a separate power relay when operating any but light loads.
In operation, the antenna wire is strung out well away from grounded metal objects and a 110-volt lamp is plugged into the outlet on the panel. When the tubes have heated, the lamp should light when the antenna wire is touched. If it lights without touching the wire, C2 should be screwed down until the lamp goes out. These adjustments should be made with C1 about one-half mashed. The panel may then screwed in on the cabinet and final adjustment made. This is done by gradually adjusting the vernier knob of the dial until the light remains lit when adjusting but goes out when the hand is removed from the dial. This may be carried to a point where the light will flash as soon as one approaches within 3 feet of the wire or instrument. It is better not to aim for such sensitivity, though, since it will vary somewhat with line voltage. A good, practical and stable point is about six to fifteen minutes or so for the instrument to acquire a stable point of operation owing to its sensitivity.
