Digital BW, The Print

I've been using this overlay on my 3MK R1800 prints as a last step in my workflow, it corrects the space to give a print closer to what you seen on the screen. It's called a Curve Layer file. Paul kindly made this available for us Elements people, since Elements doesn't include curves.

Since then, I've installed Grant's Tools in my PS Elements ver. 6 and one of the tools is Curves. I can add a bit of contrast with that... can I use that instead of the .tif Curve Layer file?

TIA!

Paul
