I've decided to start taking portraits in order to expand my portfolio. Right now it's full of everything but humans I assembled a backdrop stand, got my background "dark grey fabric", and some lamps. I just wanted to know how do you guys usually set your shutter speed for portraits. I will not be charging anything but I would like to make the best out of the session. Also if you can give me any advice regarding how to run the session it will be greatly appreciated.
