increasing size of MBs in a photo?

[raymond]

I have a D70 and I'm interested in tabletop work.
My pics are somewhere around 2-3MBs in size.
Question: Is there a way to increase that size to a minimum of 4MB?

Why would you want to do that?

The reviewers want a minimum of 4MBs for entries to be accepted.
Can you help? How do you upsize?

Upsizing is usually the WRONG thing to do AKAIK (as far as i know ) because it adds artifacts to the file and generally makes the files look worse.

Although i have not tried it I have heard of software from Alien Skin called Blowup http://www.alienskin.com/blowup/index.html

It is supposed to be excellent and they have a demo version.

Hope that helps!

Easiest way to do that would be to save your file in TIFF format. It's a completely uncompressed image file. I only know that you can do that in Photoshop, i'm not sure if you can do that in other programs.

I do save my pics as tiffs but they have to be 4MB or more as a jpeg.
I have Photoshop Elements 4 which does all that I need.

That alienskin software is $200.00...I wish I could afford it!!
