Please bring back gamma camera control

r_moore

I am using my ASI290mm for spectroscopy. It is important that I have control over the gamma setting for the camera, not the display. Gamma needs to be set to one. Your previous SDK had this option but it is no longer available. Please bring it back!
Thanks.

Please check below release note:

Since which version it is no longer available? Bug fixing is the major work, I don't think it is disabled intentionally.

Sorry I didn’t specify the setting is no longer available in SharpCap. I don’t know which SDK version, but here is the note posted on the SharpCap forum in 2018 (in quotes).

“ZWO have DISABLED the gamma control on their cameras

Hi folks - been asked why the gamma control is no longer present in 3.1 several times recently, so thought it would be worth making an announcement about it.
In a recent update to their SDK, ZWO removed the ability to control gamma on their cameras. I don't know their exact reasons, but I suspect that the thinking is that changing the gamma during capture is almost always the wrong thing to do (better to adjust post-stacking).
SharpCap 3.1 (and later versions) use this new version of the ZWO SDK, so they will not show a gamma slider for any ZWO camera - this is not a bug.”

So according to SharpCap, gamma control for ZWO cameras is no longer available. Please restore that function. Thanks!

I am not sure what happened in 2018, but I am pretty sure there is a gamma slider in our ASICap, since it has been 4 years and lack of context, I think you'd better check the current status with SharpCap.
