Has anyone experimented with shooting a roll of film on your lomo, rewinding and then shooting over the same roll? If so, have you noticed which image is more dominant? the first set taken, the second or the one with the most color? I really like what turned out in these two photos

this is a basic double exposure question, the answer applies to all camera shooting negative film, lomo or other wise.
It has to do with the limited amout of density any piece of film is capable of recording.
When an image is taken with the camera the light reflected to the film plane produces a build up of designity. the more light, the more density, E.I. a photograph of a red ball on a black background will only build up desnsity when the red ball is, as no light is refelected from the black area. If you then shoot another exposure of a medium reflected light scene, like a grey ball or something, the ball will have more film area to exposre on and be more prominent in the final shot. And vis-versa, a red ball photographed against a white background, the white will build up alot of density, probably using up 100% of the available density of the film. If you try to shoot a grey ball..or anything really, after this frame, there will be no avaialbe density for the light to expose to, you'll just get an image of a white wall. In oder to double expose an image well there needs to be density vailable for the light to build up on, so if you shoot your first exposre of a white wall, you will get nothing, or not much, of an image impression from your second exposre. And if you shoot your first shot on a black wall or scene, you will have lots of density left over for your second exposure, creating a more interesting "double expose" type image.
So to answer your question, the image that produces the most density on the film is the one that appears more dominent in the end, no matter wether it was shot first or second. The best thing to do is meter the shot you want to take, then cut the exposure in half, this leave plenty of availble material on the film for your next exposure which you should also cut the settings in half for.
God thats a long response.

I think Tim's explanation makes a lot of sense, especially the part about cutting the exposure of the second shot in half.
Just to give you an idea of how it might work, here are two examples I took:

This is actually a triple exposure. The first image is the sculpture and buildings; the second is my friend's face, and the third is her shoulder on the right side of the frame. Clearly the first shot dominates.
Example 2:
http://www.robsimons.com/tahoe-o…The first shot is of Lake Tahoe. The second image is a Cadillac on some random downtown street. Again the first image dominates, although there's a point near the back of the car where the density is equal.
Note that cross-processing tends to produce inconsistent results - especially depending on the film you use. But then again, that's part of the fun, for me anyway.

I can't say a damn thing above what tim wrote...
From personal experience I have had some awesome results and some not so good.
When I don't C-4 the film I tend to get better results.
Nothing online I'm afraid...but this:

Is very similar to the kind of thing I get - minus the C-4 - looks lovely btw

What is C-4?
You mean C41 process slide film?

jinkies timajik! Thank you so much for the explanation, it makes a lot of sense now.
Those are cool photos kj! Thanks for sharing. On the triple shoot, did you cut the expore time equally? Oh and thank you and jevad both for the note on C4 processing. Could either of you explain what is inconsistent if i do decide to try a roll with double exposure? Does the second image not come through as much or is it harder to see that there are two separate images?
You men rock. Much lovey-dovies.

Thanks tim! unfortunately, my car got broken into and both my lomo and holga were casualties of it.
:(my adventures into double exposure is put on hold for noe.
i fucking hate people
but not you guys
