Does it do it with all lenses? If so, try resetting the camera to default settings (check the manual for how to do this). Some picture styles, such as Neutral and Faithful, look "washed out" compared to what you usually see on the LCD.

If resetting the camera does not work, it sounds like it may need service.

Canon 40D playback on viewfinder flashes all white to black. On a wedding gown it is horrible on playback to review.


You're seeing blown-out highlights. These are the portions of the image that have been overexposed so much that all details have been lost and gone pure white. Usually this is a bad thing, and the camera is warning you of it. The proper fix is to reduce the exposure to bring back some of the details. If you simply want the camera to stop the flashing, see page 117 of this manual.

I have a canon 40d and a canon 580 ex, i need to set up the 2nd curtain sync, how do i do it ? respond here or email to mqlimax@gmail.com


There is a button with three arrows pointing to the right on your 580EX. Press this until the 3 arrows appear on your flash LCD. That is second curtain sync. The other function of that button is for High Speed Sync

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.

The LCD screen on my 40D shows the image taken, or the live view image, but there are large areas of missing image. Almost like the picture has been laid on a black background then a large piece torn out...


If the Live View shows areas of total black, the LCD is probably faulty and needs to be taken to a Canon Dealer for repair/replacement. I believe the pictures are still okay on the computer in this case?

I have a canon 40D and a speedlite 580 second sync not working


If you are not in P, AV, TV or M then the camera will not allow that feature. The picture modes disable many higher, more sophistocated features.

Canon 40d images appear to be too green


This is actually a white balance issue.

Not to be a wise guy, but these solutions are on pages 63-71 in the owners manual. If you don't have it, get it here:

http://canon.links.googlepages.com/Canon-EOS-40D-Manual.pdf

On P 70 you'll see the White Balance Correction instructions, I'd start there if it's a global problem. But note that there are other ways to hande individual lighting situations: Custom white balance is very easy and popular, p68. Also check out the picture styles on p63 and note you can create custom styles in that menu, p65-66.

Hope this helps.

No image on lcd


You need to enable the "live view" mode in the menu, then "set" live view as needed. When you are in this mode the shutter is open and the lens is flipped up to allow the image to hit the sensor and then to your preview screen. Because of this, the camera can't auto-focus, but there is an over-ride mode.

You may find the "video user's manual" links on this page useful to help you find and understand all the functions of your 40D.

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!
Jeff
