If it's possible, (on my Nikon it is) try to let the camera shoot it in RAW+JPEG. Not sure how to explain why you should shoot RAW, those fancy websites do it better. Look it up, I found much more room for improvement when shooting RAW.
If your Photoshop doesn't accept RAW, like mine because I have a version that couldn't bare daylight, convert them into DNG. Photoshop can read DNG, it's an open source format. Your RAW might be .cr2 (usually with Canon) and so it sometimes happens you work with software that doesn't support that format. DNG is open source, I can almost guarantee you you'll be able to open your photos the next 10 years as DNG with almost every image editing software.
