It has previously been agreed that questions from a designer point of view, about using graphics software to achieve a desired style, are not suitable for our site.
We still seem to get one of these questions every couple of days, and when we do, I usually vote-to-close with a custom off-topic reason, along the lines of:
[I'm voting to close this question as off-topic because] it is about graphic design/using graphics software, not computer graphics techniques or research.
It fits into the format but it's not ideal. Since this is a recurring pattern, would it be useful to put some better wording into one of our slots for site-specific off-topic reasons?
I'm hanging out in chat if anyone wants to work together to draft the text for this.
