Description Hugh Phoenix-Hulme 2021-03-18 15:13:52 UTC

SUMMARY
When loading a PSD file the output is completely different to PhotoShop (not just a bit different)

STEPS TO REPRODUCE
1. Load the PSD (100MB): https://www-sub-etha-link.s3-eu-west-1.amazonaws.com/ascension+ebook+source.psd
2. Compare with the PNG (5.2MB): https://www-sub-etha-link.s3-eu-west-1.amazonaws.com/ascension-ebook-cover.png
3. Note that the PSD doesn't look right when loaded in Krita.

OBSERVED RESULT
Krita's representation of the PSD is much too bright and the vector objects are barely perceivable.

EXPECTED RESULT
Expected Krita's representation of the PSD to match the PNG output from PhotoShop.

* This file in CMYK. Krita doesn't swap the multiply and screen. See bug 424525.
* Krita cannot load psd vector objects in any case.
