Channels & Masks One-on-One (by Deke McClelland. O'Reilly 2009)

Dear all,

i remember an old discussion about channels which was a bit short on references on why channels are an important concept. Although quite late a tip (and written for photoshop CS4), the book mentionend in the subject line can fill in the gap, i believe.

From a developer's point of view, it offers detailed descriptions how channels and selection tools are actually used to accomplish complex selection and compositing tasks. It also provides an explanation for some of the UI idiosyncrasies and myths associated to channels (channel were first, layers came later). Furthermore, it reveals (one) artist's view on blend modes.

Cheap-skate bonus: the book is out of print (e.g. 15? @ terrashop.de)

have fun, yahvuu

Higher rate for smooth tool?

Hello,

Im currently drawing a picture and i have a lot of selective smoothing going on. Using a selection and a filter every time is painfull. The smooth tool does the job. But if i have to smooth over large areas it looses its effect and does not smooth any further. Seams like the used kernel does not get any bigger and that the "size" has no effect. Maybe its an issue with the colordepth, and roundings produce the same result over and over again?

Any way to increase the bluring strength beyond 100? Otherwise i can't remove such "banding" as visible at the legs in this screenshot (NSFW, contains nudity):

At least not the easy way...
