Hi everyone, This is my first post. When I was in college, I shot B&W with sn SLR and developed in my own darkroom. I am looking to rediscover photography in a mild manner with a camera/lens at under $500. I am looking for some suggestions on the following: 1) Should I purchase a camera with a fixed lens or one with an interchangeable at this price level. It is basically goingg to be a re-learning camera that I can use to take good portrait and outdoors photos in B&W mode. Ease-of-use and portability is a plus. 2) I will be doing minimal post-processing. Maybe cropping and some light tonal work. I don't even have a Windows PC (I use Chromebooks and Androids). What online sure can I use for this type of processing? Thanks for any suggestions!
