Overscan area is another story and it should be cropped either before processing or even before scanning.

I only crop *after* the original SAVED, and to me, cropping isn't just to reduce the size but another level of post processing which including tilting and few extra process(es) to give the image a newer face. > Also, take note of tacit's remark.

I don' t know what Bruce Fraser is or was, but I know who Joel is and I go with Joel's technique <bg> > HFL |

Probably a miscommunication here. But, > I agree there's more to cropping (see below.) YES, most if not all scanner have option to select what you want to scan, and some even have the option to auto-detect the photo. Yes, even my 4-5+ years old Epson Perfection has the feature. > > > After the print is in hand, and before saving my changes I remove the > > > resize and sharpen steps.

I haven't done any scanning for many years to have any specific routine. About over a decade ago I upgraded to a newer scanner to scan some old family photos for restoration, then about 4-5+ years ago I upgraded to the Epson Perfection which has option to scan negative film to scan -3 old films and haven't used it since. Back to the cropping, the old Epson Perfection auto-detect and setect the photo so no need for cropping, and it allows to select the area to scan too. > > > Also, take note of tacit's remark.
