Here is my problem, thank you in advance,


- I have a controlled environment where the light is not changing,

- I have the same settings between a D610 and D750 as shown in images below

- both have Nikon 50mm 1.8g attached

- i am using  the same Neewer Speedlite 750ii on both cameras (no settings are adjusted on this flash between changing camera)

- speedlite flash settings are TTL, +3

- A tripod is used so the camera potions are identical

- there two other lights which are set as slaves, so are triggered when the speed light goes off

- I have removed the speedlite from the camera and carried out the same experiment, the images appear to be identical when no flash is used, this is making me think its a flash issue


Both camera flashes seem to be of the same power when observing by eye


I have no idea what this may be, could someone please help,


Thanks again,

No clue... unless the difference is between the EXPEED 3 software in the D610 and the EXPEED 4 software in the D750.

It's probably an issue with the ttl compatibility of the flash. Try it on manual.
