I dont know if thens been asked before but when i try to use my photshop cs2 i cant use any of my filters no matter what i do anyone care to explain why?
make sure the layer you have selected has somthing on it. use Image >> Apply Image . then use your filter
make sure it is in 8 bit mode and not 16 bit or some of the filters will not work. to change it go to image>mode
