Help. I bought PSE about a year ago, thinking it would be easier to navigate than the traditional Photoshop CS I had on my desktop. It works fine for what I am doing currently, but am not sure it has enough capabilities to do what I want to do (i.e. focus stacking, HDR to name a few things) I know Lightroom is a better choice for photographers and PS is better for digital designing etc.. Do I reeealy need LR? Is it reeealy worth the 300 bucks? I don't shoot in RAW because my computer won't open the images. Any advice/experiance?
