I forget how to mask using the color channel (in this case blue)

I know to duplicate the background layer, duplicate the blue channel, use the levels to make it as contrasty as possable.

Then it becomes fuzzy. I think there is find edges or something.

There is one tutorial that uses a selection. I thought it was on Russel site.

thankx in advance

Thankx, I had seen that one and I think that using my channels would be easer. I can get the "find edges" to do its job but how do you convert this into a mask
