Having just finished a job which involved turning a snapshot of a rather grubby young lad into a studio portrait, I thought I should share a little technique that comes in useful sometimes.
Problem here was that the young lad's shirt was all creased, and blurring wasn't an option because it had a small checkered pattern.
The trick is to use the
deGrunge technique - but with proportionally higher radii than when using for skin.
The same high-pass / Gaussian blur method but this time we want to preserve the pattern (pores) and the creases are our "grunge".
