I have a live performance that i want to make feel more active. So i wanted to try to make it look like people were taking pictures during the performance.
I tried to overlay a 60% opacity duplicate of the video that was lightened and use that as a way to create the flash but boy does it look cheesy. The keyframes over 4 frames starts at 100 and fades to 0. CHEEEEZYY:-o The blacks in the flash look too washed to be believeable.
I have Ae cs5&6 with most of redgiants plugins (2years old).
What you suggest as the best way to accomplis a realistic flashing of cameras?
