IPv6 Posted June 6, 2019 Share Posted June 6, 2019 There is a problem with "Apply Image" filter when metal is enabled and when not enabled. It produce different results. see screenshots. Right result when metal is NOT enabled (screenshot 1-filter/1-opts), when metal is "on" - result too much white (screenshot 2-filter/2-opts). In other cases it looks like like filter with Metal "on" try to make channel value above 1, clamping colors Quote Link to comment Share on other sites More sharing options...
IPv6 Posted June 10, 2019 Author Share Posted June 10, 2019 Happens with some other filters too // Quote Link to comment Share on other sites More sharing options...
Staff Chris B Posted June 14, 2019 Staff Share Posted June 14, 2019 Hey IPv6, Do you have the beta installed and if so, can you still reproduce this? I've been checking the filters as I go but this one seems to be behaving for me in the beta. I'd appreciate a second opinion.

Metal-powered execution of "Apply Image" filter in LAB mode is completely wrong // Looks like LAB values are offsetted, making everything "whitish" and causing clamping where it should not (i use this filter in macros for LAB transformations and difference is big) Quote Link to comment Share on other sites More sharing options...
IPv6 Posted June 14, 2019 Author Share Posted June 14, 2019 Curves and Channel mixer are ok, though, in beta... i was under impressions they suffer from same problem but in beta they are not. So only apply image affected Chris B 1 Quote Link to comment Share on other sites More sharing options...

hanshab Posted June 15, 2019 Share Posted June 15, 2019 selective color adjustment has this problem in LAB where it changes a saturated blue to magenta without making any changes ie happens as soon as you call up the selective color adjustment first picture is before selecting selective color adjustment second is after selecting selective color adjustment without making any changes in the sliders.

IPv6 Posted July 22, 2019 Author Share Posted July 22, 2019 Still a problem in beta 1.7.2.147 (Regarding "Apply image" in LAB mode with Metal compute enabled) // Quote Link to comment Share on other sites More sharing options...
Staff MEB Posted July 23, 2019 Staff Share Posted July 23, 2019 Hi IPv6, Yes, there's still issues here, sorry. Note that's actually the Metal output that's correct (not the opposite). The issue/log is still open for reviewing/fix. IPv6 1 Quote A Guide to Learning Affinity Software Link to comment Share on other sites More sharing options...

Hi hanshab, Thanks for your report and sorry for the late reply. This issue should now be fixed in the latest Affinity Photo Customer Beta 1.7.2.147.

"Metal output that's correct (not the opposite)" - so something changed behind LAB calculations? i see... Please, provide us (AP users, i mean) with exact information about how Affinity Photo treat A/B channels in filters, after all... I heavily use calculations over lab channels for some effects - and unusual non-documented mapping stuff (i suspect that channel value limits between Metal/Non metal was changed? or anything) does not help. As well as endless guessing for "right remapping mindfuck" to make some LAB-related filters just to work as expected // Quote Link to comment Share on other sites More sharing options...
