Hello, I was trying to take some night-shot from my room. When I turned on the flash, the resulting photos had a bright spot on them. Is there a way to use the flash to brighten the surrounding environment but do not have the bright spot show up on photos? Speaking of flash, is it a good idea to get external light such as: 1. iblazr2 LED wireless flash http://concepter.co/iblazr2/ 2. Nova Off-camera Wireless flash for iPhone https://www.novaphotos.com/ Which one do you recommend? Thanks.
