Anyone have experience shooting florescent?

    I've read some "how-to's" on it, and I know what's needed (yellow barrier filter and blue filter)

    Since I can't afford the real deal, I'm going to try some guy's DIY get up. (here's the link if anyone's interested: DIY Underwater Fluorescence Filters)

    I was just curious if anyone has had a bad/decent/good time doing this, and specifically is there any issues with focus, the way there is when you shoot infrared.

    Thanks!

    The plastic filters scratch easily and are fragile if you try to cut them yourself. I broke one cutting it with a fine saw. So do everything you can to protect them from scratches and bumps.

    I use a UV light, so don't have experience with blue filters.

    I didn't find the yellow filter helpful at night using UV light. When shooting at night, I'm mostly interested in the florescent colors. Yellow filters will correct background color with ambient or white background light.

    I haven't noticed focus issues.

    It is easy to get filters for the camera end. Getting high throughput excitation filters though is much more difficult. The dark blue acrylic will not let you get much in the red side of the fluorescence spectrum but is good for greens.

    I was wondering about that. Especially since it has to be a fairly dark blue...

    fortunately I've got a place right by me that cuts acrylic for cheap!
