Major dilemma, I'm one of those people who is
very picky with how I look in photos, someone can take like 10 photos of me and ill probably like how i look in only 1 or 2 of them.
Im going to Europe in less than 3 weeks

and its obviously going to be the trip of a lifetime, ill be going to Amsterdam, Paris and London. When im at these amazing tourist sites I NEED to look good in the photos taken of me. Im a bit stressed because i feel like i never take good photos and here i am going on a trip where ill need to take lots of photos for memories.
Can you camera lovers give me any tips on how to look your best in photos? What are the best poses, angles, etc. Help me out!!
