My photos of reds have a burned out look. How can I adjust my camera to compensate for the way my digital camera reads reds?

Meter off the red and open up the exposure +1/2 to +1 depending on how much brighter than midtone it appears. Alternatively meter off green foliage in same light go minus on exposure. Will need to be in manual or a program mode that allows you to change and lock in the exposure.

Make sure your white balance is set correctly. Red in particular is thrown off by the wrong white balance.

Here's a thread that discusses the red clipping problem and some potential solutions:

Maybe I'm not understanding the problem but to me Burnt Out Reds means they are over exposed. A previous post suggests metering of the Red and then compensating by + 1/2 to 1 stop. I think that should be -1/2 to 1 stop so that the Red becomes under exposed - i.e darker.
Of couse RAW would be a great way to go.

Colin, I understood it the same way as you - red channel clipping (or red color 'burnout") and I also thought the exposure value adjustment needed to be negative as opposed to positive.

If you meter off a color that is brighter than medium, you will have to open up as much as it is brighter. Such as metering snow, need to go + 1&1/2-2 stops. Red is brighter than medium so need to go +. Now if you meter off something around the red that is medium then would go -. For instance I photographed a white mushroom surround by green moss and metered off the moss. The -2 exposure was the best. Had I metered off the white mushroom would have gone +2.

Linda: I wonder if the camera sensor can adequately deal with the full range of red tones..? If red is being clipped, the only solution that I know is to go negative on the exposure compensation. A + adjustment would exacerbate the loss of red highlights.
I recently took some macro photos of some giant red hibiscus flowers which essentially filled the frame - the result was a nearly disastrous loss of red highlights. My saving grace was that I was shooting RAW and the Recovery slider of Lightroom worked its magic (at a setting of +39) - coupled with a negative 0.86 adjustment to the Exposure slider. My original camera setting was zero exposure compensation; it looks like it should have been negative 2/3 or negative 1.

Yeah Chuck, on my cameras red always blows out. Had the same experience shooting Hibiscus as you did. The only way I was able to match the reds was to use -2/3 compensation in the camera.

It may depend on the shade of red. Some reds probably are darker than midtone, so would need go negative. Fall maple leaves always turn out great for me at +1/2.

I was trying to shoot red lillies on a cloudy day and the reds had no depth. I called it burn out, because when I looked at the photo it looked over exposed to me. But I am such a novice that my terminology may not be accurate.
I didn't have this problem with my film camera, so I thought it had to be something about the sensor in the digital camera.
My little digital camera can shoot raw, so should I try that?

Chuck the link you gave me was most helpful. I will try some more shots and see what happens.
I did try using my software to make corrections, but since the orginal photos were so poor, I really couldn't correct the lack of depth and the "burn out" of the highlights. That may be because I'm a novice with the software.

Bliss, yes, I would recommend trying Raw. It will give you a little more dynamic range (range of dark to light tones) and the ability to adjust white balance and a number of other image parameters. It also bypasses the in-camera JPEG adjustments (contrast, sharpening and saturation) that sometimes cause a loss of fine detail in your images. It's not necessary to shoot Raw all the time, but in difficult exposure situations, it may give you an edge.
