Frequently asked questions
Does the sketch effect work on any photo?
Photos with clear subject edges sketch best, while busy or dark backgrounds produce more lines that can look noisy.
What kinds of photos make the best sketch?
Portraits and single subjects on plain backgrounds convert cleanly. Busy scenes still work, but the result reads as a detailed line drawing.
Can I get a lighter or darker sketch?
Convert once, then use the invert and brightness tools on the result to tune line weight and overall tone to your taste.
