Hello, thank you for this Ask! Yes, I have a Sony A7.. but really, taking pictures and editing the raws is much easier than you may think ^^;;. If you lock the iso to 100, you have a LOT of dynamic range (compared to higher isos) as long as you don’t overexpose. As far as I understood it, higher isos just software-increase the illumination anyway, it’s not changing the sensitivity of the sensor I think? You do need a lot of lights in your room, or sunshine.. so I use a flash to provide lights. For now, I’ve been putting the big flash on my camera itself (the A7 doesn’t have a flash of its own) I’ve been wanting to try using a remote flash (so it’s not on my camera) to make it easier. Maybe someone can suggest me something?
