Questions fréquentes
How does the sketch effect work?
The algorithm converts the image to grayscale, inverts it, applies a Gaussian blur, then uses a dodge blend to produce sketch lines.
Does it work on colored photos?
Yes — the sketch is grayscale by design, simulating a real pencil drawing.
What image types work best?
Portraits and images with clear edges produce the most realistic sketch effect.
