Hi All,

Apologies if this question has been asked/answered but I haven't been able to find the thread on the forum anywhere.

I just started using android qdslrdashboard with my Nikon D7500 and Pro Timer 3 and have watched Gunthers tutorial many times and followed the instructions but when I capture the sample image I just can't seem to register a reference value. Lum and Reference is always zero. I get a histogram and am able to change all the settings but no matter what I do a can't get that reference value to register.

Any advice will be greatly appreciated.

Hmm, that's strange. Normally, after "capture sample" the lum value should be filled and when you activate the auto holy grail, you should get the reference value also.

Did you set the camera to Raw+Jpg(Small)?

If everything looks right, it might be a technical issue, which you'd need to contact Zoltan for via https://dslrdashboard.info
