Light Pollution Model bit depth issue

Hmmmm, 6 months and no reply.  I guess no one else has had this issue?

I've never seen this happen in APP. I'm assuming that you have checked the actual bit depth of your lights - you haven't accidentally switched to 8 bit captures ?

I have to ask why you are using such large selection boxes and why they overlap. I always use small, non-overlapping selections. I vaguely remember reading years ago that that is best practice. I may be talking rubbish here but I wonder if using large overlapping boxes has upset the math used to derive the correction model ? I guess if you redo it with small non-overlapping boxes and the problem goes away then you have a likely answer, otherwise I'm stumped. 🤔

Hi John @johnbsys and @connor231,

Can you check the bitdepth of the light/integration that you are trying to correct? I have never seen the model like this on 32bits data, so it could be that your data is indeed 8-bits. If it is not, maybe you can upload/share the file that you are trying to correct? Do you see this problem in the latest version 2.0.0-beta38?

@mabula-admin Thanks Mabula.  I saw that Beta38 is out but I have not downloaded it yet.  I will check my images bit depths the next time it happens. I am at a star party now for the weekend.  I will download 38 and try it out.

Thanks,

Great John @johnbsys,

Please let me know if you need more assistance with this and/or if the model looks again like that 😉
