Ive been trying to decide on a backdrop setup. I work for a school that assembled for the first time since it was built to have a year book for this school year (small private school). They knew photography was a hobby of mine and asked me to shoot portraits of their high school students. I decided to up my arsenal of photographic equipment and now im trying to decide on a backdrop. Is 6x9 too small - I know I have seen much wider and longer so how am I limited with 6x9?. I would like to try out chroma key - but Ive read that you need extra lighting to light the green backdrop. Thankyou!
