Low Res Images - Are they safe
« on: August 07, 2009, 01:10:37 PM »
Found this on a local newspaper website -

 "People wishing to submit photographs by e-mail should file them to picdesk@archant.co.uk. Photographs should be sent in JPEG format, and a file size of at least 200KB to 500KB is necessary for good reproduction in the newspaper."

Seems like a very small file to be able to print.

Spose it would be ok for a newspaper though.  A glossy magazine would be a different story.  ;)

Depends on the print process and paper stock.  500kb would give a nice quarter page in most mags.  Easily go full page in a newspaper.

Also depends on image content.  When I shoot high key of kids the files are amazingly small.  Lots of similar tones + smooth skin = tiny files.

But is that your choice or a function of the camera due to the limited data it needs to record?
And more, much more than this, I did it my way

It's a function of the jpeg compression algorithm.  A large area of white will compress extremely well.  The classic measure of a large file is a bundle of sticks - all the texture and detail = huge file.

I shoot kids on a D3 (12MP) in jpeg at fine quality (minimum compression).  Some files right out of camera are 1MB or less.  I'd be happy printing them to 60X40 :)
