A6300 and external flash question

[token83]

Hello, I've just bought a Godox TT350s flash to use with my A6300. I’d like to be able to dial in negative exposure compensation to darken the background without altering the flash output. As I understand it, the A6300 offers this option by allowing the user to choose to apply exposure compensation to "Ambient & Flash" or "Ambient Only" (Menu > Custom Settings > Exp. Comp. set). However, when I use the latter option with my flash set to TTL mode, I get both a darker background and a slightly darker subject! Any thoughts why that might be?

Hi @token83

Did you post this question on a video on Youtube?

I saw the answer you received there and will check it out and get back to you.

Cheers

Hi again

I've been informed that this could happen because you use TTL mode

and It shouldn't happen when using non-TTL mode with your flash.

Hope this helps

Thanks for your reply. For the record, upon further testing I determined that the problem mainly occurs when shooting a backlit subject indoors, e.g. a person in front of a window. In those cases, one can overcome the issue by using flash compensation. I got different results when shooting outside as in those situations selecting the "Ambient only" setting affects the ambient light but not the subject (as expected).
