There is much to love about the Indra500, but I do have one issue. I guess most problems here originate with TTL, and in a way so is my problem. But not in the original sense.
Because I want to control the Indra500 power output via the Odin TCU, I must set the Indra500 to TTL. However, the color temperature is way off in the lower power region when I do this.
Indra500 set to manual - color temperature is pretty stable, well within +-200k from 1/8 to 1/128 which is satisfactory.
Indra500 set to TTL, but Odin TCU set to manual - color tempaterature shoots up +1500 - +2000k (!) when I shoot in the lower power regions such as 1/128 and thereabout!
What on earth is the Odin TCU doing even though I have set group which the Indra500 is on to manual?
(I use a Nikon D750)
Edit: Updated Odin TCU to 1.08, made no difference.
Edit 2: Have provided RAW files here:
I did 10 shots in a sequence with Indra500 set to 1/128 and set to completely manual, and then changed Indra500 to TTL and kept Odin on manual and 1/128 and took 10 more shots in a sequence.
If you want to save bandwidth, I recommend grabbing the following files and compare the two:
