It does in my case, but then I've been doing it for a long time and I have 10's of 1000's of images online. Just how many 10's I'll keep to myself, but stock photography is how I make my living and accounts for 90-95% of my income.
However as I said in the piece, this $1 per image per year, only starts to become a reality when you have something like 10,000+ images up for sale.
Its a long haul business and should be approached as such.
Unfortunately the editing and managing is far more time consuming (and far less interesting) than the shooting. Its about 10% pressing the shutter, and the rest sorting it all out.
I have a photoshop action which adjusts the levels of each file to 5 > 250. I just press a function key and it does it. I also have raw processing presets in ACR which give the file more "headroom".
I use Photoshop for everything. I've got a lot of automation set up, again lots of pre-recorded actions.
I'm working on one of the new MacPro i7 laptops, which is blindingly fast and I can use anywhere. I also have a seperate somewhat aging aging MacPro tower which I use for bulk uploading and which has 8TB of internal hard disks for storage.
