Question about Canon EOS 40D Digital Camera

1 Answer

Colour representation on Eos 40d

The colour saturation and representation appears to have become much poorer with all pics appearing weak and slightly overexposd . I had a 20d , found that this was an issue and so bought a 40d as a replacement - but no joy
Pics taken 3 years ago excellent but now with 1500 photos taken in Nepal devastated by poor quality colour , in bith auto and semi auto functions .
Even looking at a new canon 40d I have found that if youm take a photo of say a red traffic light on full auto 400 iso is used and the light appears AMBER
Please help a totally frustrated ( previously ) happy snapper

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!

HI, I set my camera for Tungston bulbs which I use to shoot art. The images come out very brown. I can fix them in Photoshop but why is this happening?


try taking the shots with the camera set to daylight and or on auto colour balance.
daylight is 5600. k or if you like rather blue tungsten light is normally 3200 k. k stands for kelvin as in colour temperature. many digital cameras will sort out the colour for you but make sure that you are not using a mixture of light as this will confuse the colour saturation and give you all sorts of colour problems. what are you trying to photograph anyway. the back ground area must be lit for detail or you will get a blue noisy mess that tends to mess up the over all exposure. you need defused light for the best easy results. tell me more so i can understand your problem better

Every time I attempt to take a picture with my cam EOS40d, I get an error 99.I turn of the camera but error keeps appearing.


Check for clean lens to body gold contacts.
Take the lens off the camera. Look at the gold contacts that are in the body and on the lens. Many times, it's a simple process of rubbing a pencil eraser on these to remove dirt/film on them to allow proper contact. BE CAREFUL not to allow eraser crumbs to fall in the camera body. You can tip the opening slightly downward while you're cleaning... a lens brush can help remove any crumbs too
Let me know if it clears up your error.

Photo appears saturated green when set on manual setting


The image you selected for Custom WB is probably inappropriate - it may be shot somewhere else with different lighting or not enough of the image is white/grey. To do a proper Custom WB, take a picture of a white or grey card in the same lighting conditions as your subject. Go to menu, select Custom WB and choose that image. Then set your WB mode to Custom (if it's not already).

When you move to another site to take other photos, you must change your Custom WB image to another 'current' one. As the sun progresses through the day, your Custom WB will need to change as well. Auto WB will, in most conditions, be able to deal with changing light if you prefer not to keep updating your Custom WB.

My Canon 40D can't handle bright yellow and reds. It blurs the detail and overly saturates the subject (flower close-ups) - so that the bright red poppy is overly saturated and lacks detail even though...
