Hi all,
I have a sony a6000 and a nikon sd-80dx flash (that I am mostly using in manual mode). This flash has an auto ability (I think this was a bit before ttl came into game) that can independently of the camera calculate the right flash power.
I have synced it with the camera making always sure that my cameras shutter speed would kill any ambient light. The shots I got that were mainly lit by my flash were quite accurate.. meaning perhaps that the auto mode of my flash is doing the job nicely.
The way I am working with it, and I want some comments if I can do it better is to
(for indoor places) pick a low iso on my flash and on my camera. On camera keep the same aperture and shutter speed and start with the same iso with my flash.
Typically I bounce the flash over the walls that this normally eats two or three stops. I found it faster taking iso from 100 to 400 fast enough to compensate for this loss without changing dof or shutter speed.
Does this sound a reasonable approach to use a flash in auto mode (no ttl)
Regards
