Two particular pieces of software that have saved my life during this project happen to be free. The first, Renamer is a simple program that does...you guessed it, renames stuff. When Your dealing with 36,000 + images, you'll find yourself needing to rename many things in bulk. This program is a little tricky at first, but it rocks once you get the hang of it.
The second, Audacity. Audacity is another free program that is used for editing audio. To program is extremely easy to pick up, even for those that have never edited music. It has some very useful features, including a ton of filters. And, of course, its free. Can't beat that.
I highly reccomend any digital film maker to grab these.
And no, I didn't get paid to put these here. I did it for free. heyooooo
