Hi Leaf,

You mention The Wacom tablet, tell me how do you like it, how often do you use it, and what size of tablet is yours?

Thanks,
Kone

I use a technique smiler to the one described on this video:

Creating a White Background with a Channel Mask (http://www.youtube.com/watch?v=dG9mSC1kGvg#normal)

Yeah, that is a useful technique for creating an automatic mask.  It works well for items shot on white.  I should have really done my tutorial on an object that was sitting on a busy background.

I have the smallest tablet - 4x6 I believe.  I like to draw with my wrist and not my whole arm so I chose the smallest one.  To pick the size I needed I looked at the screen, then with a pen on a piece of paper, looked at the top right corner of the screen and moved the pen to what I felt was the top right of the paper.  Then looked at the bottom left of the screen imagining I was moving my hand with the mouse on the paper - drawing with the pen as I went.  I looked around the screen a bunch of times from all the corners and eventually got a fairly defined box on my paper.  I measured it and bought that size of tablet.

I couldn't use photoshop any other way now :)

Here is some more Wacom discussion (http://www.microstockgroup.com/index.php?action=search2&search=%20wacom&sort=ID_MSG|desc)

With images on a busy background, I usually use the Pen Tool, but for fine details, like hair or the outline of the cookie in your tutorial (almost regardless of the background business), I find it the best to use the channel mask technique.
