[PRODIG] digital file sizes for magazines

[Becky Hill]

Hi all,   wonder if you could help with an issue I have. I have a Nikon D100 which produces files of 17MB - which at 300 dpi is 25cm x 16cm. I've heard many people say that this is fine for an A4 page in a magazine (maybe even A3) ....but wonder how this is so, as an A4 page is 29 x 21cm.   Thanks,   Becky
