My Nikon D90, when shooting RAW, my camera comes up with a NEF file. NEF is not acceptable according to Adobe, what is the easiest way to convert to files that photoshop is happy with. I have searched previous posts and have not been able to find an answer, (No doubt this has ben discussed at length in the past, but I can not find results) Please, I need help! as a rookie with all this 'modern stuff', I am finding it a bit of a struggle.
