Today after i made a wallpaper in Photoshop, i closed it and opened it after half an hour and now every document that i open is whitened out. While moving the document window i can see the original colors, but once i stop moving the window it whitens out almost like some Blending Options settings were used as soon as it was opened. Has anyone else been having the same problem? How can i fix this, I can't make anything in Photoshop because all the colors in the document are whitened.
Try restarting your computer if you haven't already. Did you make any changes to Photoshop's preferences before you closed it? Perhaps undoing what you changed may fix this issue. Seems more like a graphics error though.
reinstall photoshop reinstall graphics drivers upgrade-reinstall windows/OSX reformat and reinstall OS and programs...
