I was wondering what everyone's opinion would be on only offering b&w proofs for the net, with the proof watermark in the center.
Here is why I am asking.
My workflow is to move the pictures from the memory card to HD1 *takes half an hour, usb2*, move the original jpgs to folder named original jpgs. Color correct the cr2 files which takes about an hour for 180 pictures *average amount I get from an hour portrait session*, I like to go file to file to tweak the color of each set of pictures to make them look their best. Especially with outdoor shots, I find the color changes every few minutes.
Then I run the batch conversion and save all the files as jpgs reduced to 1500x2250 pixels *almost 5x7* size which takes upto a few hours *they are originally 18mp*. I normally do this part over night so it does not take away from my productive time.
Then I take the files, crop them so they look their best and slap on my watermark, merge and reduce the size for the internet.
At some point I copy the pictures to HD2 and DVD/Bluray. Sometimes right away, sometimes after the color correction and crop. It all depends how fast I need to erase the memory card.
If I were to skip the first part, and work with the original jpg's and convert them to black and white so the color didnt matter, this would save me a bit of time. I would still loose an hour having photoshop do a batch resize of the jpgs for me so I can load 40 of them at a time into photoshop to crop, but it would save me a couple hours probably.
As an added bonus, people would less likely be happy enough to save the proofs, and they may be encouraged to buy more to get the color version.
What is everyone's opinion on only offering b&w proofs?
I realize another solution is to get some usb 3.0 hard drives and get a top of the line desktop, but thats not in the budget atm.
