First, sorry about my verry bad english...
How to work around with the problem of the strong magenta cast in the sky ? Particulary when the sky is strong blue.
I have tried every thing : custum white balance, RAW white point, overexpose, underexpose. And I don't want to use PS for all my photos with sky. The 990 manage this very well. The automatic and daylight white balance presets in the G1 manage this VERY badly.
Should I change the G1 for the new 995.
I hope not. Can anybody help me ?
Best regards,
Eric

These photos are not mine.
So this mean that this is not the fault of my G1.
Best regards,
Rico

Many user complain about the magenta cast problem. It is not you, and not your camera. It is also not the G1 only that gives magenta cast. Because the cast happens in different amounts, and different colors depending on the shooting situation, there is not one cure-all to the problem. If you have Photoshop, I've found some very powerful tools to help you undo the magenta cast. If you would like to try it, send me an email at vitoj@proaxis.com and I will send you a step by step procedure that usually works for me.

I seem to be having this problem a lot, but most of the time "auto levels" in Photoshop (elements) seems to be what it needs...
I'm wondering if putting a filter on the lens would help much in this case...
It doesn't seem to always do it, but in most cases the pictures are a bit on the light side and a slight magenta/greyish cast.
I usually use -1/3 - -2/3 of exposure compensation, which avoids overexposure for most pictures...
Any suggestions ?

I also get this problem. Especially when the sky is very dark and there are clouds, the clouds come out magenta. I have heard theories that the magenta sensors on the CCD are sensitive to infrared light, but don't quote me on this.

I shot a macro of a blue wildflower and it looked magenta in the LCD before I took the shot. I reasoned that this couldn't possibly be true because I look at the flower; it is definately blue. I look at the LCD; it is definately magenta. I took the shot and it came out very magenta, just like the LCD said it would. Still in position, I increased color saturation and the magenta went away entirely. This was probably just a fix for this one shot because conditions change so much from situation to situation but experimentation is worth a shot, no pun intended.

Oh.. this could be it: white balance.
I remember having white balance set to "indoors" and outdoor pictures gave be pink skies.
Try to cycle through the white balance settings until you get one that makes things look good.
