Links:

This page contains links to software that I use, most is Open Source and available free.
It is by no means a complete list, there are many other good programs available.
You will not find links for Photoshop or other 'non free' software
You will have to 'Google' for those.

Other links are to sites about equipment and digital imaging resources.
