Very unique colors

[JeremyLangford]

I found this film photographer who shoots double exposures and does no computer editing to his pictures. His pictures are very colorful and different. I am really wanting to know what kind of technique he uses to achieve the interesting and unique colors that he does. He gives a hint to what he does in this link......

Anyone know exactly what is being done?

Double exposure of different speed at different time?

It looks like he has a set of three colour filters, red green blue, and he moves the camera and focus between each of three shots (perhaps a fourth w/o filter?) - the filters add up to a Neutral Density grey colour so where nothing has moved/changed appears in natural colour.

That's my guess

It looks like sometimes he only uses two of the filter, so then most of the picture is yellow (green and blue filters).

yeah looks like filters with multiple exposures to me.

I did something similar--not as good as these--with a fairly basic set up.
Three color filters; red, green, and blue. A tripod. And a camera capable of multiple exposures. And color film(either slide or negative).
I didn't move the camera but anything in the scene that moved would be imaged in a different color and anything static would be normally colored.
I shot a fountain near where I worked and the water was multi-colored while the fountain itself was brick colored.
You'll need to work out the exposure times; the three exposures will need to be equivalent to. I think I decided the easiest way for me to do it was to take a reading for my scene with f22 and then use that shutter speed and open the lens 3 stops for the red filter (f/8) and 2 stops for the green and blue filters (f/11). So if my meter read, for example, 1/125 @ f/22 I then shot 3 exposures on the same frame; one through the red filter--1/125 @ f/8--and one through the green--1/125 @ f/11--and one through the blue filter--1/125 @ f/11.
You could google "Harris Shutter" and "tri-color camera" and get more info about this technique.
To see a ton of images shot this way search Flickr for "harrisshuttereffect".
