When i need to tidy up old film photo album , it's hard, can not just go to trash can. so i decide to change it to digital, first i try with DSLR camera, but qaulity not so good. so then change to use scanner . generally A4 scanner is suitable for myself. some good automatic scanner can scan 4x6 or else size of photo , but it's too expensive , so i must use A4 scanner. while scan, not just 1 photo in 1 page of A4, so i decide arrange as many photos in A4 scanner 1 page, after that then cropping each photo manually . it's really hard ... and i m not good at photoshop. so i decide it's not man's work, automation !! need program. i will not mension about another programs , but i remember at least 5 or more programs i tested, but all result is not so good. can not detect photo well. so finally i decide make program myself. ... but it's really hard time starts. i just guess it does not take much time. ...
