I just got a new Imac and CS4 isn't supported, big surprise. I need a program that can do all the basic photoshop stuff, cropping, shadows and highlights, contrast, unsharp mask, etc. I don't do much photoshop work, I'm old school. If it doesn't look reasonably good out of the camera, I'm not spending much time on it. Is Elements all I need, versus the full, expensive, subscription-based photoshop?
