Brain function - User constraints
Posted: Sun Apr 14, 2019 12:46 pm
Hi Robin
I have started using the brain function to calculate the optimum exposure gain brightness/black level. However I have a large library of Darks + other calibration frames for bias, etc that I use and the issue with the brain function is that it proposes basically new exposure times, gain settings and brightness/black level every time so you would effectively always be shooting calibration frames.
I usually hit apply then change the figures to the nearest I have for exposure / gain, would it be possible to have the ability to teach Sharpcap the extent of this library or step parameters you want to use and then get it to chose the nearest match to what it is calculating to avoid this. you could even display both values as this would give an indication as to whether it would be beneficial to create extra calibration frames at a certain exposure / gain.
The reason for this is that last night for the first L frames I just hit apply and then altered the values for exposure / gain as normal and then for RGB I just typed the settings in with out hitting apply and this has caused a few issues as the brain function would appear to set brightness / black level to 100 at some point in its calculations and as this tab was closed on my display I did not realise subsequently my calibration frames are not working.
Cheers
