What are the basics of photo-shoots and photo editing? - photo editing

I am a graphic designer, I got my BFA. I have a job where I did not want to photo-shoots and editing photos. (I want pictures of small objects, such as cosmetic use), and finally I'm going to do the design work. What principles should I know about getting photo-retouching and photo shoots in the job, I'm a bit nervous!
