for the tiffinfo output, i still has two questions desiring kind help from you.

1. what means "ICC Profile: <present>"? and what is ICC?

2. i noticed this file is uncompressed. so what's the benefit the lab save
in tiff rather than a bmp? result

thanks in advance.

Celine: I had worked for this old man and once he told me that he had spent his whole life thinking about his career and his work. And he was fifty-two and it suddenly struck him that he had never really given anything of himself. His life was for no one and nothing. He was almost crying saying that.
