CIECAM02 black picture with algorithm 'all'

hholt · April 6, 2018, 4:27pm

By playing with ciecam in dev-5.4-144 on win10-64 and using ‘all’ as algorythm in image adjustments the picture part of RT got black. Changing enlargement brings the picture back for a second or so. By using all other algorythms there is no problem. So I don’t know is it ok or is it a bug? Perhaps someone can test.

Many thanks

For me it happens with a processed image. It happens not if I start from neutral. I’m on 5.4-133-g16679296

Can you provide a raw and pp3 file to reproduce?

Thanks for the files. Still can not reproduce here using 5.4.148

I think I found the culprit. Screenshot shows the solution

We should remove the option to use the old double precision ciecam02 code…

After changing the setting there is no problem any longer. Many thanks to https://discuss.pixls.us/u/heckflosse

Thanks for reporting

I created a pr to remove the ciecam02 double precision stuff for RT 5.5

Yep, works now.
