Testing out an infrared sensor I picked off of the auction site, works pretty good. I put a 3.5 mm plug on it and hooked it to the camera axe. Model number is E18-D50NK.

The poor Canon 700D is struggling to find light as G522 and XR557 head south towards Wallan as #9306, up Tocuwal goods.
We didn't plan to capture this, although we decided to find a spot just for experimenting with the new lens.

The first thing to say is that each electronic sensor has a protective filter over it, so we are not actually touching the electronics. That would be a disaster. Most people send the camera off for a service and a clean and that's a very good idea. After all this is an expensive investment and we want to make sure our camera works as well as possible for as long as it can.
But, it is quite easy to clean your sensor at home. All you need is a kit (like the one I've shown). This includes sealed sterile swabs and a little cleaning fluid (they are essential - do not try to clean your sensor with a cloth where you can scratch the dust into the sensor filter). There are also many videos on YouTube showing you how to use these dust cleaning swabs, but provided you get the right size for your camera (mine is full frame) a simple swipe will suffice.
For a DSLR you obviously need to lock your mirror up before the clean, and then lower it immediately afterwards. Then with the other side of the swab give your mirror a quick wipe as well. Do not apply too much pressure. After all, these are only tiny dust particles - you should not have any dirt.
My Leica D-Lux 7 which I used to take these pictures has a fixed lens, so it will never need its micro-four-thirds sensor cleaned.

Amazing. I finally cleaned my sensor and I'm overjoyed with the clean skies! This is pretty much right out of the camera, no cloning out dirt spots. Taken in Felicity, CA, just this side of the Arizona boarder.
What a beautiful camera, I really love taking pics with this! Only 18 years young!!!!!! Australian grevillea btw, and it was also a bit windy and getting dark

This is not a crop.
To clarify, my title refers to the view through the lens. Because of the nature of prismatic reflections (rainbows, etc.), it is impossible to actually view a rainbow from the inside. Rainbows always are viewed toward the opposite of the light source (usually, the sun). This photo is not a crop, as I said above, but it was taken with a 500mm lens (1.6:1 sensor yields 800mm equivalent on 35mm film).
Shot at FL-Studios. Post-processing done in Capture One 20.
The heresy continues... that Goerz (taking lens) dates back to around 1904. Such gentle rendering. Perfect match for digital!

Encara que parega que el sensor estiga brut, realment són gavines volant i avisant del temporal que s'apropava.

Nikon D810 Photos Pro Women's Surfing Sports Photography Tamron SP 150-600mm F/5-6.3 Di VC USD !
I shot in DX mode which crops away the extra pixels and takes me 1.5X closer while allowing for up to 7 FPS with the Nikon D810's Nikon MB-D12 Battery Grip using the 8 AA battery option! 8 Duracells took me through around 3,000 shots no problem--maybe more! I was shooting at the equivalent of 900mm with the 1.5x crop factor! Pretty close! Had I gone with the Nikon D4s, I would have gotten 12 fps, but no DX crop factor, as the sensor has only around 24mp, compared to the d810's 36 megapixels! Sure the larger pixel size on the Nikon D4s full frame sensor comes in handy indoors or at night, but in the bright sun, there's more than enough light for the smaller pixels in crop mode! Sure we lose some pixels from the outer edges when shooting in DX crop mode, but most of those pixels would be cropped away in Lightroom anyway. And the smaller files make the memory cards last longer, while also upping the FPS to 7 shots per second! Not quite 12 FPS, but still awesome and enough I felt!
What a beautiful way to test the Nikon D810 and Tamron 150-600mm zoom lens for sports photography!

View your artistic mission into photography as an epic odyssey of heroic poetry! Take it from Homer in Homer's Odyssey: "Tell me, O muse, of that ingenious hero who travelled far and wide after he had sacked the famous town of Troy. Many cities did he visit, and many were the nations with whose manners and customs he was acquainted; moreover he suffered much by sea while trying to save his own life and bring his men safely home; but do what he might he could not save his men, for they perished through their own sheer folly in eating the cattle of the Sun-god Hyperion; so the god prevented them from ever reaching home. Tell me, too, about all these things, O daughter of Jove, from whatsoever source you may know them. " --Samuel Butler Translation of Homer's Odyssey
All the best on your Epic Hero's Odyssey from Johnny Ranger McCoy!
These cameras are fabulous. I love the lens coupled to the DX size sensor. Light - easy to carry and a great focal range of 24-120 (in 35mm terms). This camera can prduce great images to rival many DSLR's. Its not as flexible and the low light capability is limited - but in dayligh its superb and the night shots I have taken are also excellent (great star bursts from this brilliant lens).
I have two of these cameras - I definately need to sell one but will never be without at least one!
Mandrill in der Wilhelma Stuttgart - REVIEW - G7 X - Mark II - D+, HTP aka High Tone Priority
Canon Powershot G7 X Mark 2
Canon PowerShot G7 X Mark II
The effect of HTP is enhanced by Canon's 14-bit A/D converter, which provides finer tonal gradations than the previous 12-bit system.
HTP affects RAW data as well as in-camera JPEGs.

HTP*: ermöglicht mehr Informationen in Highlights bei zu behalten
aka 100 mm
HTP, D+ - a Canon EOS DSLR tool - an alternate methode of Image processing
- allows more Information to be reatined in Highlights
- avoids overexposing
- it shoots at ISO 125 but records 250
- HTP exactly equal to underexposing by 1 stop
- it brings back texture and detail
- improves gradiation in bright Areas (Highlights)
- HTP changes the sensor response curve for RAW, not just JPEG.
extending dynamic range means
better color results in the overexposed Areas and
lowering the highlights
* D+ - Highlight Tone Priority (HTP) - mode
Highlight tone priority is a camera mode that internally fiddles with exposure to preserve as much detail as possible in the "highlight range" of tones.
Noise in the shadow areas mat be slightly more than usual.
Hence HTP affects the way the sensor records the image before any processing and hence it affects both RAW and JPEG.
PS
Some DSLR photographers often underexpose by 1 stop because sensors lose information in the highlights much easier than in the shadows.

Der Mandrill ist eine Primatenart aus der Familie der Meerkatzenverwandten.
Tribus: Pavianartige (Papionini)
In der vom Weltzooverband WAZA geführten Artendatenbank ISIS wurden 2007 insgesamt 493 Mandrills als weltweiter Zoobestand registriert.
Im Disneyfilm Der König der Löwen ist der Charakter Rafiki ein alter, weiser Mandrill.
Er lebt in Regenwäldern Zentralafrikas und ist für seine rot-blau gefärbten Partien im Gesicht und am Gesäß bekannt, die ihn zum farbenprächtigsten aller Säugetiere machen.
Mandrills kommunizieren durch visuelle und akustische Signale, durch Gerüche und Berührungen. Vermutlich hat die leuchtende Färbung der dominanten Männchen eine Signalfunktion beim Führen der Gruppe im düsteren Wald.
Ist ein Tier aufgeregt, verstärkt sich die Gesichtsfärbung.
Daneben sind auch Gesten bekannt: das Präsentieren der Eckzähne ist eine Drohgebärde, ein heftiges Schlagen auf den Boden drückt Ärger aus.
Es sind mehrere Laute bekannt, darunter Grunz- und Kräh-Laute bei der Nahrungsaufnahme, ein Alarmschrei und ein zweiteiliges Grunzen, mit dem das dominante Männchen die Gruppe um sich sammelt. Auch die gegenseitige Fellpflege (Grooming) spielt eine Rolle bei der Kommunikation.

Agfa Sensor Cameras
Agfa Silette LK Sensor
Agfa Optima 200 Sensor
Agfa Optima 500 Sensor
Agfa Selectronic Sensor
Agfa Selectronic S Sensor
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.
Price about DM 450,-
