I am planning to get a 5-n-1 collapsible reflector and a light stand, primarily for use in outdoor portraits. This will be my first use of reflectors. What size reflector would be best for me to get, perhaps 32" or 42" (if I only get one right now)? Also, what height of light stand would be best for this use, 6 feet, 8 feet, or ??? I really only want to buy one of each at the moment so am looking to figure out what to start with that would be versatile. Thank you in advance for any advice.
