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,

Hi Becky,
Don't be frightened to res it up. You can increase the file size to A4 (or A3 if you like) in Photoshop and it will still look better that an image scanned from film taken by an equivalent film-camera under the same conditions.
That's because the digital image has more clean information per pixel (unaffected by film grain and emulsion) than the scanned image of the same size.
Try the comparison yourself if you need to be convinced (or to convince your clients).

Dear Colin
Can you also let me know which magazine repro departments will do cheapish proofs to try the comparison. Now that so many have changed to CtP I know of nowhere I can make reasonably realistic comparisons of different file types or sharpenings.
I'd be interested how Becky will convince her clients without this.
