depends on what your rendering.... extract makes for fuzzy edges.. and can be a real pain.... best tool is pen/path tool... crisp edges... perfect control...
good stuff ghettolt / for tires and other round objects I switch to quickmask mode and then use a hard, round brush you can actually pick the brush the size of the tire / using the pen tool also allows you to "modify" the curves. this is the long and winding road... but gives excellent results. /since we now can upload files to the GR forums, why not upload the psd with the render? some peeps are already doing this. best of course would be to upload the psd AND post an example for those people not using photoshop allthough some programs can import psd files. >>pinned<< good thread for reading up on some technics...
So it's actually better to use the pen tool than the extract? Hrm, i may need to try it. My current sig i extracted, but then had to blur some of the pixelated edges =/
yes, the lasso tool? Look at the tool bar on the left, hold ur mouse over the tools for a sec or two to see their names. You select around the render and press delete thats how it works.
