eureca, I remembered !! After selecting the area, invert the selection and delete. Select the transparent part and apply the effect.(that's what I forgot) direct and without duplicating. thank you all.
hi, How to make this effect? shading... I did this on this image several months ago and I don't remember and I don't think I used any plugin. Note: I don't know if I used "Pencil Sketch" because the content also changes. regards,
