Ideally, though, I'd like some way to combine all the frames of the moving image into one still image. Anyone know if that is possible?
Thanks for the input!
You can do that in an image editing program like the Gimp, which is free...
But stick the pointer so you can't see it, otherwise you'll look at it and spoil the test... you want to be blind to it until you see the results.
But ultimately what you're looking for is a scatt. But if you can get the pointer to work then it will be a cheap stop gap.
