Hello I've done my first maternity photo shoot but I think the photos are too dark and dull. I did not use any extra lighting and did not use flash because my instructor is always telling us not to use it. I followed everything he has taught us but I still did something wrong. So, i tryed fixing the pictures by lightening them up but when i printed them, they did not look anything like i saw on my computer. Some look ok but others look like i fixed them to much, the contrast is off. How do i get my computer to show me exactly what the picture is going to look like when it's printed? Also, how do I avoid taking dark pictures again? Should i use my flash regardless? PLEASE HELP!
