black artifacts in my PNG image and how to correct them.
Hi community.
Which method can I use in PS to eliminate these blocky artifacts? (I tired adding noise to it.) Also when I'm in front of the screen its less obvious, when I see the image from the sides of my monitor its more obvious.
Also what method can I use so that PS just targets the black areas on my image? and doesnt tamper with the rest of the colours?
