Question about Canon EOS 40D Digital Camera

1 Answer

Photos taken on Canon 40D are often 80% grey - and rest is clear!

Recently I took 100 photos in one session. On the display, they looked fine (at least I didnt see anything odd) - but when I downloaded it to my laptop, half the pictures would not open as thumbnails. And whatever program I used (on the damaged ones) would only show around 20% of the picture, rest was grey... almost as though chip in canon had not been able to capture all the image. And yet when I flick through damaged photos with Picasa, I can, for an instant, see the whole picture... and then it goes back to 80:20.

So 2 Qs:
1 - why does this happen? Problem with 40D, or flash memory, or something else?
2 - how come I can see the photo for an instant... and is there a way of recovering what was lost? Tried various applications, but none have helped.

Camera is 6 months old, nothing damaged, new lenses. Flash memory, 8Gb.

Any ideas? Many thanks in advance.

Felix

An My Canon EOS40D does not respond after taking 100 consecutive photos while taking a time lapse photo. I am using an Alpine Pulse intervalometer.


Have a look in the manual - some cameras have this as a 'fail-safe' in case people forget and leave them unattended. There may be a way to disable this 'function' in the menu system.
Just looking at an answer to another similar query for this model, you may also need to disable 'automatic shutdown'.

My display screen is showing pixelated noise, or completely black. When it does display, all I get are off colour, horizontal dancing lines.


Camera is defect for sure, but don't tell anyone in the service centre, because they warn you not to take a camera out in extreme cold. You should not se the camera in environments below zero degrees
I'm afraid you can't fix it yourself, and before bringing it to a Canon Certified repair centre, ask them what it could cost.

My Canon 40D LCD monitor when displaying a photo has just started displaying white sections of a picture as alternating black then white. The rest of the photo is fine just the white flashes. Any idea what...


It's possible that your Highlight Alert is enabled. Over-exposed areas of your image will blink to indicate blown-out whites. If you don't like this feature, go to the Menu, under the second blue tab (for playback), look for Highlight Alert and Disable it. When viewing the image on a computer, the blinking will not appear however. It's just to warn you that some parts of the image is so bright that all detail is lost. I enable mine so that I know this and is able to make adjustments on the ground.

Camera takes grey photos


It's kind of difficult to troubleshoot or diagnose a problem if you don't specify the model camera you have. Canon has made over 120 different models. You can check this service notice and see if your model is mentioned in the list under Affected Products.

Colour representation on Eos 40d


Have you checked your white balance? Having an improper white balance is one of the most common color problems with digital cameras. 
If true color is what you're after, then you need to tell the camera what true white is, too. Try either shooting a grey card, or using an expodisc. For each lighting situation, you properly expose a shot of the grey card, or a blank frame using the expodisc, and then you set your camera to use that image as the white balance image. Now, your camera will see what you see a whole lot better. Keep in mind that the auto white balance is just a best approximation of what the camera thinks it sees. However, in many situations, there is not only one light source. There are reflected light sources, diffused light sources, and direct light sources all over the place — all of them different color temperatures and intensities. The grey card and expo disc help take these all into account. And while it may seem like a lot of trouble to set the white balance all the time, I think it will be well worth it when you (and everyone) else is amazed at the true colors you are capturing.
Happy shooting!

I would try another card with the camera to see if there is a fault in your camera or the USB cable. If the other card works fine, then there nay be some compatibility issues with the M type XD card in your camera. Just for reference: I have several older FujiFilm digital cameras that I still will not use the newer style cards with. Newer meaning the 'M' and 'H' series cards. Fuji says they will work fine, but I'm always leery of newer techno gear being 100% compatible with older stuff.

Here is a link to Fuji's memory card chart: FujiUSA
