Green trees on a suburban street in the morning sunlight. This picture is straight out from the camera, no processing except darken a the brightness a bit. What I call the magic of the CCD Sensor, no longer used in digital cameras.
Made with the Pentax Optio Z-10 point and shoot.
Hatte ich folgendes nicht schon an anderer Stelle geschrieben?
1. Beim Filmtransport verschwindet der belichtete Film hinter einer Klappe, so ist er bei versehentlichem Öffnen geschützt.
2. Man spult den Film mit dem Schnellschalthebel zurück, nachdem man vorher einen Umschaltknopf betätigt hat!
3. Die Auslösung über den roten Sensor-Punkt ist wirklich sehr sanft und erschütterungsfrei.
Richtig! Diese drei exklusiven Merkmale der Selectronic Sensor findet man später wieder in den genial designten Optima-sensor-electronic-Modellen.
Der äußerliche Unterschied fällt natürlich sofort ins Auge. Die Selectronic sensor hatte die recht konventionelle, für die damalige Zeit aber moderne sachliche Form der Optima 500 fortgesetzt. Ein großer Erfolg war die die Selectronic nicht, aber das Innenleben hatte sich so bewährt, dass es mit kleinen Abwandlungen für die Optima Sensor electronic übernommen wurde.
Während aber die neuen Optimas einen voll programmierten Paratronic-Verschluss besaßen (man hatte keinen Einfluss auf Belichtungszeit und Blende), war die Selectronic sensor ein Zeitautomat: Die Blende wird vorgewählt, die Zeit dazu wird von der Kamera errechnet und eingestellt. Beide Werte sieht man im Sucher. Dieses System gefällt mir viel besser.
Es gab noch die Selectronic "S", die mit dem Vierlinser Solinar statt mit dem Dreilinser Apotar ausgerüstet war und außerdem einen Messsucher besaß.
Die Selectronic kostete 1971 349,- DM, die Selectronic S 449,- DM.
Made in ?? ; 1978 - ... . For 126 cassette . Simple viewfinder camera with fixed focus and aperture . Two shutter speeds . Socket for flipflash flashbulb bar .
I have had some dust stuck on my sensor since getting my A7III and sadly the rocket blower couldn't remove it. I usually pay to get my sensor cleaned but decided to give cleaning it myself a try and I'm glad I did.
This is to compare 10 MP sensors in a digital SLR (DSLR) and a point and shoot (P&S) camera. I have tried to keep everything on equal footing with no unequal cropping of the original images. Both images were taken at the equivalent of 75 mm from about 1,000 feet away. View this FULL SIZE here: farm1.static.flickr.com/171/476181751_dae004f4a5_o.jpg and scroll through the image to compare the resolution at various points of the images. After you click on the link, you will have to mouse over the image to get a magnifying glass icon. Click while holding the magnifying glass over the image and you will be able to view it full size.
To me, the P&S sensor practically looks like an impressionist painting compared to the DSLR sensor. This is also the "large size" P&S sensor, as most are using the smaller 1/2.5" (5x4 mm) sensor.

Lens
The compact Canon PowerShot SX70 features a 65x Optical Zoom Lens paired with a 20.3 Megapixel CMOS imaging sensor. It’s equipped with a minimum focusing distance of 0cm3 and has zoom up capability of up to 2730mm. All these features combine to create beautiful close-up shots as well as being capable of stunning wide-angle photography, without having to go about changing lenses.
Video
Take crisp and clear film footage using the PowersShot SX70’s video capabilities. The OLED Electronic Viewfinder, approximately 2.36-million dot, high-definition, offers an accurate representation of what the lens is able to see. This is in addition to the 4k video shooting and grabbing features.
The latest Canon camera has is the first point-and-shoot that the manufacturer has made that’s compatible with the latest RAW format (.CR3).
Digic 8 processor
Canon’s latest Digic 8 processor is also among the highlights one can find in the SX70. With this additions, we should now be seeing an improvement in image quality when compared to the 16.1MP chip used by the SX60 HS.
Like the SX60 HS, the lens is still at 65x, almost half of what’s been outfitted on the new Nikon P100.
The maximum aperture range is F3.4-6.5.
OIS
IBIS
It’s also worth mentioning that the camera’s image stabilization system is made better with the addition of a new image processor, which is able to reduce shake by as much as five stops.
The SX70 HS can shoot bursts at 10 fps with focus locked or 5.7 fps with continuous AF. UHD 4K video can be captured at 30p with a bit rate of 120Mbps.
The SX70 continues to offer a microphone socket. The camera’s wireless connectivity includes Wi-Fi and Bluetooth.
St. John, Washington. Population 526. Street scene on Sunday morning, 9:30 a.m. This is a state highway I was standing in the middle of. I stood there for a few minutes to compose this shot, took the picture, walked back to the sidewalk, decided to cross back over the street and all this without one car coming through town.
My husbands sister and her husband own a house in this small town. We stayed here for 2 nights and let me say that it is dark and quiet in the middle of the night! We got up Sunday morning and walked to the local cafe, which would be just behind and to the left of this shot. 16 ounce cup of coffee and 16 ounce hot chocolate to go = $2. Now there is a deal that can't be beat!
While we were at the cafe, we began to visit with a couple who were having breakfast. They are farmers, living out of town a bit. It was fun to talk to them and hear their life in this small town. Their kids have grown and moved away to the west side of the state. This is not a prosperous area, in terms of people having lots of money, but I'd have to say that it is indeed prosperous in it's quality of people. Everyone we encountered, all 10 of them, smiled and waved at us. Made for a nice Sunday morning.

I am refinishing these photos in Lightroom 5! She was a tall, thin, fit, athletic goddess and classic california beach babe! A pretty brunette with brown/hazel eyes and long black hair! Amazingly scuplted and toned body, abs, quads, legs, calves, biceps and more!
Shot with a Panasonic DMC-FZ50--a nifty little camera that still had a CCD in it, instead of the cmos sensor! It's close to Micro 4/3 and the Leica lens/ glass is awesomely sharp!
All the best on your Epic Hero's Journey from Johnny Ranger McCoy! :)
She was as pretty as she was muscular!
A pulse rate detector (or pulse sensor) measures heart rate (BPM) by detecting blood volume changes in capillaries using photoplethysmography (PPG). A green LED shines light into the skin, and a photodetector measures the reflected light, which varies with each heartbeat. This data is filtered, amplified, and converted into heart rate.

One of my Fuji X-Pro1 bodies is broken. It will power up, take a few shots, and then shut down. When I try to turn it on, it sometimes gives a message that says to turn the camera off and try turning it on again. I have also noticed a large, diffuse, white defect in the upper right quadrant of the sensor.
I later concluded that I had damaged my sensor while shooting a solar eclipse. Rather than repairing the camera, I decided to replace it with a Fuji X-Pro2.
After great demand and lots of encouragement from friend photographers, the result of this very work intensive project is finally available. Please check your respective amazon online store.

Content:
This book is unique, in that it focuses on greatly improving photography skills, both for amateurs and professionals, by understanding the image sensor & camera operation and the impact of parameters changes on image quality.
Are you one of those photographers who continuously fights excessive image noise when shooting birds-in-flight, a photographer who would like to understand why certain camera and lens settings do a great job and others don’t, or, are you a photographer who fails in creating top quality images, independent of the circumstances? Then stop looking, because you have found your comprehensively written expert guide, created by image sensor specialist George F. Vittman, PhD, who has worked with world-renowned specialists in the field since the mid-1980ies, and who is also an outstanding and award-winning photographer.
Without going into too much technical detail, this book introduces the basic image sensor operation, and it devotes a large fraction to the study of visible image noise. What is noise caused by, what is its dependence on the 3 camera exposure parameters, shutter time, lens aperture and ISO-value, how does post-processing affect noise, and most importantly, how can the image noise be minimized under different circumstances. Besides image noise, this book also reveals little known secrets regarding auto-focus, camera operation and optics, and it gives image sensor based recommendations for a camera choice in the different fields of photography.

This shot shows the light source pointed into the front lens area of the box camera under test.
It is a green light because the sensor is most sensitive to green wavelengths.
The playing cards are a convenient way to shim up the light source the proper amount.
"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.

The photographs in my set, "Weed Flower Micros," may appear to be close-ups of regular-sized flowers – they are not!
These are micro (macro) photos of tiny little flowers which bloom on ordinary weeds found in my lawn.
How tiny? The largest weed flower in the set is only, when measured across its widest part from petal tip to petal tip, 3/4" in diameter (19mm)!
Some of these miniscule flowers are so small that the entire blossom you are looking at is 1/4" in diameter (6mm)…or smaller! Again, that’s measuring from petal tip to petal tip across the widest part of the bloom!
The smallest part of a weed flower that I have managed to successfully shoot and achieve good detail in is a photo I made of a bud that measured LESS than 1/32" in diameter (0.7mm) across its widest part!
For size references I have included a photo of certain flowers and buds next to the head of an ordinary paper match, which dwarfs the blooms and buds.
It’s delightful to discover the beauty, complexity, and variety in something so small that it’s easily ignored, taken for granted, dismissed as a pest, or just downright difficult to see with the naked eye.
And it’s an even greater delight to realize that this incredible beauty has been growing wild in my lawn, year after year, right under my un-seeing eyes as I’ve repeatedly mown them down with my lawn mower, never realizing the unseen beauty that I was trampling under my feet.
I hope you enjoy viewing these as much as I do. I have a lot of fun making them for us to look at!

A Sandia sensor for detecting toxic gases is now smaller, faster and more reliable.
Its performance sets it up for integration in a highly sensitive portable system for detecting chemical weapons. Better miniature sensors can also rapidly detect airborne toxins where they occur, providing key information to help emergency personnel respond safely and effectively to an incident.
“With rapid analysis, operators can learn about an exposure to toxic gases in time for people to take personal precautions, evacuate an area and mitigate potential damage,” said analytical chemist Joshua Whiting.
