Dear Qiu,

I may have started this topic in the wrong category, so I ask it here

as I think it needs someone who knows the ins and outs of the camera to answer my question.

Can you pls inform about the relationship of the

Gain used in the graphs (0 - 100)

and

the digital number the gain can be given in e.g. the setup window (0 - 339)

Does the gain number in the graphs represent a percentage ?

Is the number 339 equal to 100 % or to 339 % ?

If 339 equals 100 %

then putting gain = 30 in NINA is only about gain = 8.8%

Can you pls provide the correlation between both percentage and the gain number we enter in e.g. NINA

Thank you very much.

Johan
