So I kept reading about how super duper the matrix meter on this camera is, so I've been giving it a shot the past week or so.... Any of you guys have an issue where all pics shot with a flash are underexposed by a stop? It's fucking weird. Every single one of em has a histogram that stops just higher than 50%. 1 stop exactly in LR makes all of em perfect... I've zeroed out all of the other settings on the camera, and if I dial in +1 exposure comp. it looks great in camera... It's only with the matrix meter and the flash in the hotshoe... Thoughts?
