Greg that's much better compared to the original.
I personally like to have a little bit of a gap on the left of the histogram before it starts to rise, it gives a more natural looking background.
I highly recommend using a dedicated computer with a good monitor that's regularly calibrated.
I have a dual monitor setup, Dell 2408WFP and a Dell 2209WA and use the Spyder Pro to calibrate them regularly.
I make sure I have the same colourspace running and have "Proof Colours" ticked under the "View" menu in Photoshop, (thanks for the tip Jase).
Anyway mate glad to see the repro.
Cheers
Andrew
