While playing around with the 70-200 VRII + Canon 500D I had a first go at focus-stacking.
I used 7 shots at f/16 with equal displacements via Camera Control pro and auto-merged them in PS CS4. No other post-processing.
Unfortunately the merge blew out the left side and left some unwanted "residue" around the shell. You can see it in the large original prominently on the left border of the shell.
Does someone know whether I have to manually work on each individual mask or is there a faster way to eliminate the residues?

P.S.: this is already the second version. I made it from jpgs developed from RAW in CaptureNX2. The 1st version was stacked directly from the NEFs in PS CS 4 and showed some nasty green coloring in the residues. Obviously some CA that Adobe's Camera RAW could not eliminate.
Ernie (see post below) suggested how to eliminate the problem. So here you already see the updated version. Thanks, Ernie!
