Question about Digital Cameras

1 Answer

I have a Canon 40D. Sometimes the picture that plays back on the LCD shows spots that blink between white and black especially if there is a white background or if someone or something has very pale colors. How can I solve this?

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.

Sometimes, when I take a picture with my 40d the automatic shutter speeds that display can fluctuate dramatically from 100th of a second to 10th of second in just a split second before I press the shutter,...


your camera is probably set to SPOT exposure instead of AVERAGE exposure,. Which means, your camera is taking readings from a smaller area within the frame instead of using the whole frame to decide exposure. When in spot exposure you can move a hair and the exposure will change dramatically. does this make sense? put your camera back into average metering.

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?

Blinking black in play mode!!!! PLEASEEEEE HELLLPP


Hello,

If this is the same as my Nikon this is the overexposed highlight display option.
This shows areas of the photograph that are overexposed slightly.

On my Nikon I use the up and down arrows on the back to cycle the LCD display options.
Stop when you get a display that does not flash.

Hello cherdh,

To disable those blinking spots, just press the up or down cursor keys at the back of the camera while in playback mode. You will get three different views. One shows the EXIF data (Image data) as an over lay on your photograph. Press the button again to go to histogram mode, with graphs. Press it again to go to a mode where some image data is on the bottom of the display with no blinkies on the image.

Those blinking black spots are called highlights in a photograph. They indicate the areas where your photograph is over-exposed, i.e. where there is too much light and the colours are washed out. It can be a good tool to get a good exposure. Keep clicking with different settings till you get an exposure without those blinking spots.

I hope this helps.
