Solution found to red shift in G1

[Grant Dixon]

Just recently I was photographing a extreme red Geranium and got a very bad colour shift to the blue. Well is slept on this problem and the next day I decided to check the White Balance Setting. I photographed the same plant first in AWB then cascaded down through all the colour options. The day was cloudy and surprise of surprises the colour was tack on in the "Cloudy" setting, but still terrible on AWB.

So the conclusion I have come to is that with a very strong predominance of red the AWB is being thrown off toward the blue. I should have suspected this right off the bat as many algorithm tend to fall down under extreme conditions. The automatic balance like an averaging light meter works for the majority of times, but it is only a tool and it is up to the photographer to know when to use it and when not to use it . That being said , whenever possible, I will for not rely on the AWB. Finally the red colour shift that have bothered some with the Canon G1 is not a problem at all when you know your camera!

Grant,

Thanks a lot for your post. I will give the "cloudy" white balance setting a try on some red flowers. Hopefully, this will give me some good results as well.

As always there is a lot to learn to make the shots their best. Problem is remembering what I have learned when the shot is trying to get away.

Grant,

DId you take the image in Raw mode? If you get a chance, could you try again in Raw, and see if specifying the White Point in Raw works as well as specifying it in the camera? Not that I don't trust canon that raw is really raw, but....

This would explain why I have never seen the infamous "red shift" problem. I almost always shoot in raw, and manually pick the white point.
