BUILDING MY OWN PRE-FLASHER
Posted 15 September 2005 - 12:57 PM
Just wondering if anyone here has made their own, and if there's any advice you would give?
Looks like I'll have the ability to control the intensity of light, as well as the ability to control the color temperature, by either:
A. Separate RGB controls.
B. A simple filter slot, perhaps even one that will take the CP-16 filter holders, which I already have right there inside the camera.
Which would you do?
Probably going to use LED lighting, to get around how tungsten bulbs go orange over time, etc.
I've never done flashing before, so obviously I'm going to have to shoot mondo tests, but perhaps some of the more experienced people here can give me some advice & pitfalls about that.

Give some thought to a flashing device that puts light on each frame by using a beamsplitter.
If you decide to use LED's, match their colors to the film's spectral sensitivity peaks:

The main thing is that the Panaflasher uses some sort of built-in Minolta light meter parts so that you can measure the EV value of the flash and adjust to the level you want consistently.

We were discussing whether or not to go with an electronic, or physical solution to the intensity function, & I'm going to stick with whatever is proven to work.
