I want to switch from Photoshop to Affinity Photo. I need it for Web Pages. Unfortunately the JPEG Export reproduces very bad quality. After export the pictures seems to be radical sharpened and have enormous artifacts by same file size as with Photoshop.
My example demonstrate the same picture in 300% Magnification, left is exported with Affinity Photo, right with Photoshop. The original had 36 MP, both are exported to 2400x1600px with JPEG compression to a file size of 170KB.
If I want a comparable quality to Photoshop, I need a file bigger than 250KB. This is not acceptable.
I use macOS 10.13.1 and Affinity Photo 1.6.6 – but 1.5 had the same problem.
What can I do?
