pixels on image review

eatalotapeaches · 03-26-2009, 03:36 PM

I have a question about my new K20. After you take a pic and the "review" pops up briefly on screen, the darker portion of the image is covered in yellow pixels. This happens sometimes, but not always. Should I be worried or is the camera just telling me something?

There is nothing wrong with your K20D. It is showing you where the dark/bright areas of the photo are, like telling you: "hey, over here there is no shadow detail or highlight detail". You can turn off this feature in the playback menu. Look at page 227 of your manual.

I have been reading the manual, but mostly skipping around. I didn't know what to search for. Page found and issue fixed. Thanks!

Great screen name! What part of MS? I grew up in Hattiesburg.

Another way to fix this problem is to dial in a little positive exposure compensation

But then you would have red pixels instead of yellow...

And in seriousness:

Red Pixels are worse than Yellow Pixels, because underexposed shadow areas are just too dark, whereas blown-out highlights are impossible to recover and hard to make look good (even if you're shooting RAW).

Matt is right. This is why I prefer to use the histogram preview vs the flashing pixels preview.

Yes, the yellow/red highlighting is pretty annoying to me as well much of the time. I am more inclined to the histogram myself. Regardless, am I the only guy around here with the Pentax Magic Lantern guide for my camera? That dang thing was (and still is) a great resource explaining all this stuff.
