I was experimenting last night with a painting with light technique, that I picked up from someone else on here. Basically ISO200, F/8, 10sec in a pitch dark room, and selectively paint the subject with a flashlight. Worked fairly well, blue led light wasn't the best choice, but it got me thinking...

What about extending the idea to my 430EX. Set a 10-20sec exposure, run around to several angles of the subject, and trigger the flash each time. You could quickly emulate a very complex lighting setup on the CHEAP, especially if you had a few makeshift filters in your pocket to manipulate the light differently.

Anyone try something like this before? I may give it a go this evening

i have done this on flowers as an experiment. I didnt like the way it looked. give it a shot and let us know.

You arent going to get a (person) to sit still enough for that length of time. Try a still life or an object.

Some people use this technique to create "ghosts" or multiple copies of themselves in a room through the fake multiple exposures. that can be neat.

If you want cheap flash get a peanut slave and a vivitar 285. then use the bounced 430 on camera to trigger it. you can get awesome strobist results like that for about 100.oo

Or get a flashzebra 15 foot cord and put your 430 off camera.

Those are just some other ideas. have fun.

Painting with light can be incredible. If you're ever seen Tony Corbell's demonstration of painting a small jet plane with light using Quantum flashes it's pretty incredible.

It does take some practice and experience but it can produce some stunning results.

yeah, that might work better with a thrysistor flash
with the automatics set for your lens opening
that way the flash will have the proper exposure at any distance from the subject..

on the other hand, I have done it with the flash hand held and connectd to a shoe cord. ( camera on tripod )
I made several exposures moving the flash for each then sed the HDR in psCS3 to merge them:

One of my favorite shots when I was a youngster was me playing pool with a single exposure multi flash shot. I was in the frame 5 times. Digitally, I recently did this with a model. I lit several parts of the image separately then masked them together in photoshop. It was way easier and I did not have to worry about the model moving too much and could use a short exposure to control the ambient. It certainly had a surreal look to it.
one problem you will have with the setup you describe is the model will have to be perfectly still for a period of time.

Unfortunately this is not something that's on YouTube. It's one segment of the DVD

Tony Corbell / The Power Of Light: Location Lighting Controls

He explains the process of setup, metering and shooting pretty well.

If you're not familiar with Tony, he was one of Dean Collins students and has since gone on to make quite a name for himself.

Well from my first attempt yesterday with the flashlight I found that lighting the face first, and then trying to avoid further lighting it while hitting other angles helped a lot. That and having a subject that can sit very very still.

Maybe useful for a group shot (flash manually at each person)

While painting with light will certainly work for people it is best used on static objects that you do not have to keep from moving. People will move slightly even if you ask them to stay perfectly still.
