Originally posted by jac Took 11 shots at my son's gym w/flash. 8 at ISO800, 3 at ISO280. 2 of the ISO800 processed nicely and the rest had the magenta cast. Unfortunately just shot raw. The previews looked normal so I did my usual and deleted the originals from the SD card. Oops! Bad move. But since two did work out there still seems to be some random element involved.
Just found a solution if you have Photoshop or PSE. I exported the magenta DNG to the desktop and the preview was fine. Opened it both Adobe products, saving back in the same folder as a *.tif file. When I imported this back into Aperture, the cast was gone. Seems like a painful expletive deleted solution but at least a work-around. Or, I suppose, any other other conversion process. Interestingly, the two posted snaps at converted to '.jpg's so I could attach them and the cast is still there.
