Success and Another Question
PostPosted: Sat Apr 05, 2003 12:15 am
Thomas, Ian, etal
I?ve tried v602r08 and no longer have any memory problems and have been able to succesfully scan a 645 negative at 4000dpi with an SRD selection applied to the base layer.
My setup is:
Mac Blue&White G3 (350MHz)
OS 10.2.4
896 MB RAM
SS 120 with 120 film holder
PS 7.01
I started with an abused 645 B&W negative and scanned it full frame with 48 Bit RGB at 4000 dpi. The resulting file size was about 300MB.
After prescan I entered the SDR mode and created an irregular selection on the base layer. To check for problems I had with previous versions of SF, I added and subtracted a number of additional selections to and from the initial selection. The result as shown on the naiigation panel was
I clicked ?OK? and and then initiated a scan. SF performed normally except the whole scan process (RGB Scan, Dust&Scratch Removal, etc) took in excess of 20 minutes. But, it worked.
Ian, note that it is very slow, but interestingly it appears to be about the same speed you observed with your 1.25 MHz parallel processing G4.
Thomas, note that the image size was well in excess of the 4000 pixels size you had trouble with.
At this point I am pretty happy just that it worked.
But I still have a question. In the screen grabs of the navigator panel in the preceeding messages (Ian?s and Thomas?) the number of cells shown is a much lower number than I am faced with. In one case there was a matrix of about 5x6 cells and in another about 3x4. I get about a 12x13 array. It was implied that all were at 4000dpi. I suspect that the earlier screen grabs were at some lower resolution.
Messing with my system it appears that the cells are always about 632 by 548 pixels and that the only way to change the number of cells applied to a given image is to work at a different resolution. I find that making a precise selection when the image is broken into over 150 cells with heavy red lines marking the boundaries is nearly impossible. At best it is very gruelling.
Thomas, is there some way for me to change the number of cells and red lines in the navigator image without changing the resolution? Or, can I create the selection on an image at low resolution and then apply that selection to the image at the resolution I want to scan at?

I tried to include screen grabs but I couln't break the code.
