Re: Using channels to select pixels

[Rob Antonishen <rob.antonishen@xxxxxxxxx>]

Step 24 is interesting. Water spray is seperated from a background colour,
using a manipulation of channels.

I can't seem to figure out how to the same thing in gimp.
Any idea how I can do it?

There may be an easier way, but what I will do is decompose the layer to a new image.  Identify the decomposed layer that gives the best match to the desired selection, then drag that layer into the channel panel of your original image.  You can then load it as a selection, and further use quickmask mode to tweak it.
