Seeing RED

[jmh]

Anyone else have the problem with their Canon adding much too much red to their photo's? I own a 10D, shoot commercially, always RAW. I've even had the issue shooting in studio and doing custom white balances.
The issue is easily corrected in PS CS...but would save tons of time for lots of processing.
Thanks for the help.

Yes I feel like my shots out of my 10D seem to be a bit heavy in the red range. Nice site btw, very nicely done.

Yes, I agree. Images taken with my DRebel that contain a lot of red (flowers, etc.) are always way overexposed on the red channel. I use C1 LE to convert the RAW files. If I adjust the exposure downward to try and recover some of the red channel, then the image tends to be underexposed over all . I haven't found a completely satisfactory solution yet. :cry:

Thanks...glad you liked the site. Always good to hear.

...now, is there a way to solve the red problem? Or is it just something to deal with when shooting Canon?

same here, red is always over saturated. The only way I've found to deal with it is to desaturate in the camera raw window.

I love those interior shots jeff, what sort of shutter speeds are you using?

[jmh]

I would take the time and setup custom white balances...If I thought it would help. My studio experience tells me differently. Besides, I'm usually shooting within a 10 minute window of light being optimal...so without an assistant it would be kinda tough.

As far as the shutter speeds? All over the map to be honest...anywhere from 60 seconds (yes, I purchased the digtal cable release...another pet peeve of mine. They've managed to take something that was simple and cost $10 into something that cost $70)...anyhow, like I was saying. 60+ seconds to a 30th. Just depends on the lighting. It's not something that's an exact science.

Correct me if I'm wrong but I thought oversaturation of reds was a common problem in most digital cameras. I found the same problem trying to photograph some roses. Underexposing the picture slightly was highly successful.

This is more a gamut issue than a white-balance issue. Simply put, the camera captures a wider array of colors than is available in Adobe RGB (and especially sRGB) and will thus either compress them or clip them, depending on your rendering intent, when converting to a common working space or to a printer space.

You could work in a wider-gamut color space like ProPhoto RGB and then convert to your normal working or output color space but risk posterization; you can adjust white balance but risk a broader color shift; or you can try Glenn Mitchell's saturation mask technique which I find works quite well for isolating just the clipped colors:
