Hi John,
        Excellent work, but one question.

What scanner are you using? Colours are excellent,
and unsharp mask is very accurate for that resolution!!!
Specially Kodak Royal Gold 100, truly superb scanning.
If your lab has proccesed these prints, please tell me
the address. I think you must have scanned it with
slide scanner, haven´t you?
Great work,

Dave

Dave,
All of the slide scans were done by Firehouse Imaging Center onto Kodak PhotoCD's. Many, but not all, of the C41 scans were done by Kodak by asking for a Picture CD when it was processed. Some of the C41's are also from PhotoCD's. My best luck has been with PhotoCD's. The Picture CD's were OK early on in spite of lower resolution, but lately the Qualex lab creating them for my region has gotten sloppy with some of them. I have enough unfilled PhotoCD's on hand now, that future ones will simply be added to exisiting CD's at a cost of $1 each until they are filled.

The raw scans are not directly usable. They are too big and require adjustment of contrast/balance, sharpening, and resizing before using them. I use Digital Light and Color's "Picture Window" for handling contrast, balance, resizing and unsharp mask of the raw images.

You might explore using Kodak PhotoCD's with PhotoShop or PictureWindow to process the raw image scan. My experience with PhotoCD's is they capture enough information to pull a superb image out of the scan, but that they _will_ require at least contrast, color balance, and sharpening before resizing them. I keep the unsharp mask parameters to the very minimum needed and preview areas of the image at 2X to 4X of full size to see if the sharpening is too much before committing to the sharpening. There is a learning curve to creating good digital images from film scans. Not certain I'm totally there yet, but over time have gotten better at it with experimentation to optimize it.

Hope that helps . . . and thanks,
-- John
