We present a tool for Galaxy Automated Surface PHOTometry (GASPHOT) in deep
and wide fields, presently under development at the Observatory of Padova.
The performances of this tool in the case of HDF-like images are presented
. For galaxies having a magnitude of 24-27, we obtained a Delta M = 0.02-0.
1, Delta log R-e = 0.03, Delta n = 0.02-0.5.
