Magic Lantern firmware for Canon cameras is AWESOME. Easy to do all kinds of stuff like pull focus for video, highlight fringes around in-focus subjects for shallow DoF work, zerbra-striping portions of the live view that are over/under exposed. Audio monitoring with headphones, manual audio gain, disabling the auto gain.
All kinds of sweet crap. Just page after page of awesome custom menus with inline context help and full help built in.
There's even a freaking clap remote trigger. You can set the sound level to trigger a shot remotely. Set the camera on a rock on a hike, stand with your sweetie, snap your fingers behind your back, takes a picture.
Oh, oh, and there's a slit-scan mode. I think we might be able to use this for finish-line work... but I need to try it out. It looks like it takes a series of low-res images, then there's some free software to chain them together.
You can even do HDR video where each frame alternates between two ISO levels, then free PP software to blend each pair into an HDR image.
Just freaking awesome. I'm going to donate some $$ to the project. This software is incredible.
