I am pretty close to Scottes;
Short answer me too.
Long Answer:
After doing a photo shoot. I have three runs through to eliminate pictures.
The first run is just to eliminate the junk (out of fucus, bad light, makes model look real bad, etc..) I will occasionally find one or two really great shots at this point and edit them in PS for printing (but I don't print yet).
In the first run, each picture gets about 4 seconds. (for example I will run a total of 829 images down to 133)
The second run is the "is this a good shot" run. I eliminate anything that is not as good as the whole of the set. In the second Run each picture gets about 8 seconds. Unless I have to, I never do the second run on the same day as the first run. I am also very vicsious in getting rid of pictures (or at least I try to be). I almost never edit a picture during this run. (at this point those 133 go down to 55 images left)
The thrid run is the ugly run, at this point I try to choose the best 24-30 shots for doing a portfolio print book up. (on the example shoot I ended up with 12 I printed with about 29 total I spent time editing), three of which I used artistic filters on. The rest were just crop, contrast and sharpen. In the third run I take as long as it takes to get to the desired number.
After the third run I go into photo shop and take them one at a time, I will usually eliminate 4-6 images at this point because the full resolution shot shows something I missed in the previous three runs and just don't like.
When done the best 9-12 shots go on my web site and up to 30 get printed if we did a TFP session. (in the example I printed about 6 (since it was a me paying shoot and 9 went on the web site, but only 3 images did I both print and post.)
Later (like months later) I go back and start critizing some of my work I did earlier. (in my example done in March, so far, I can't fault any of my final prints or images I posted. They may not be perfect, but they are some of my best wrok SO FAR.
Bit long, but that explains my way of thinking.
