Re: Reducing image size

I shoot raw and keep them at full resolution and then render out the
correct size i need. The downside to changing the resolution is that you
will lose detail and you will never get it back. so the first step is to
play with the various resolutions and see which ones look best to you.

This is a good discussion on this very concept. I would suggest you take a
peek at it.

A mouse trap, placed on top of your alarm clock, will prevent you from
