Just What Is "HDR" and How do I Access It?

[jrsherman]

It is my understanding that "HDR" allows one to use the editing properties of SF 5.5 on a previously scanned file. I have loaded "HDR" on my hard drive (SF 5.5 PC Win 98 Polaroid SS4000 Neg-a-Fix upgrade PS-6). I have a picture on my screen I go to; Edit/ Preferences/ Plug-Ins & Scratch Disk/ Choose/ and I cannot find "HDR" on the tree, there are several choices but not "HDR". When I look in Windows Explorer I can click on Import_Export I see SF HDR (a 2,576KB 8BA File), when I click on it I return to PS 6 and the picture I had on the screen but there are no SF controls . How do I work in "HDR"?

HDR allows you to use the full dynamic range that your scanner or input device has stored in a "raw data scan", a so called 48 bit (or 16 bit) file.
Instead of driving a scanner, you open a file from your hard disk and use all the functions of SilverFast Ai in HDR and save your "Final image" to disk or tranfer directly to Photoshop.

For more explanations and a nice tutorial read the guides from Ian Lyons:

My problem is I cannot get into "HDR". When I go into "HDR" from PS6/ Import I open up to a picture of a Myan temple and I cannot scan a image of mine into SF HDR. What am I not doing?

HDR is NOT designed to scan an image - it is scanner independent. You MUST have already scanned the image, uncorrected, using whatever software you have and save it as either a Tiff file ot Jpeg (MUCH better a tiff file). You then open the image using HDR and carry out your colour corrections, etc.
