[filmscanners] Re: Vuescan 7.4.2 and saving RAW files



I'm with Wolf on this one.
I use an SS4000 at 4,000 dpi most of the time and I am now waiting an extra
long time to catch a Save. Since my viewer is set to Photoshop as the
default viewer, I now must add this to the extra read time for the Tiff in
Photoshop and I am really waiting a longer time. It isn't impatience, it's
just that it now takes longer than it used to.

Subject: [filmscanners] Vuescan 7.4.2 and saving RAW files


Recently I sent a note to Ed asking about a performance feature that I
believe no longer exists in the 7.4+ versions of VueScan.

I stated:

In previous releases of VueScan (versions 7.3.7 and up) saving a RAW file
was significantly improved by scanning and writing files at the same time.
With version 7.4 and up this very important feature seems to have been
removed. Perhaps the disappearance is because of the enhancement that
applies Infrared cleaning and Size reduction filters to RAW files before
saving them. However, if Infrared clean is set to None and Size reduction
set to 1, then VueScan should still (as it did in the past with version
7.3.13) save RAW files while scanning.

Ed kindly and promptly replied indicating that the performance should be a
bit better in 7.4.2. Unfortunately, VueScan 7.4.2 still seems to scan the
image, then apply whatever filters are appropriate, then save the RAW file
to disk. It does this even if all filters are set to none. Saving a large
RAW file to disk can take considerable time -- 40 seconds with tif
compression on my machine.

In contrast, release 7.3.13 of VueScan saves the RAW file to disk
synchronously with the scan. When the scan completes, the RAW file is on the
disk. On my Nikon LS40 with VueScan 7.3.13, I can scan and save a full
resolution (2900 dpi) 64 bit RGBI file (59 MB) in 137 seconds. With VueScan
7.4.2 the time to scan and save is 175 seconds -- an extra 40 seconds.
Please note that I set no filters (like infrared cleaning) or size reduction
to the RAW scan.

Am I the only one who misses the scan/save performance feature of 7.3.13? By
the way, I am also in the camp that does not want any processing (infrared
cleaning or otherwise) applied to RAW files.
