Removing odd bits of leaf lifts impression of fence? (1-3)
I believe the answer is:
e-fit
I'm afraid I can't even guess how this answer relates to the clue.
Can you help me to learn more?
(Other definitions for e-fit that I've seen before include "image of suspect" , "Computer-generated picture for identification" , "Computer-generated form of identikit image" , "Digitally generated representation of a face" .)
