Has anyone tried "PhotoAcute" Studio with a "consumer" scanner, such as the V-750 Pro

I emailed the support team at PhotoAcute and inquired if their software could be calibrated for a flatbed scanner. I shared with them the link of this thread. If and when I receive an answer, I will share it with this forum.

Thank you

If a profile really shows more promise than we see above, it would be useful to be able to order custom profiles for different lens, film, scanner combinations?

Kirk,

I believe different profiles would be required for different scanners, and for each scanner, different scanning mode (dpi, reflective or film).

I do not believe that the fim type (Velvia or Provia, for example), Focal lens, aperture or other set-up do require different software set-up (different profile).

But then, I might be totally wrong.

I totally agree that if the results allow a gain of, let's say, 50% resolution (1.5x), making the Epson 750 a "3200 dpi" scanner, it will definitely be worth the investment.

Different scanner profiles are available in SF and high end scanner software for different color and b&w negative films now. To completely profile a scanner you would have to take into account grain size and characteristics of the film etc. a factor that may be akin to incorporating sensor array data and pixel density for profiling DSLRs. Right now it doesn't matter allot because the prosumer flatbeds cannot resolve grain, but if you were able to come close to resolving grain, the characteristics of that grain would start to become important as it is in drum scans to avoid grain enhancement etc. If you are going to bother profiling a major piece of your workflow, why do it halfway?

Here is the answer that I received from AcutePhoto's team. Do any of the experts on this board know of a way to generate the most accurate film target that they would need? This would amount to following a similar process to that used, for example, by Kodak to generate their IT-8 targets, right?

Thank you for your interest.

In principle, it is possible to create a profile for a scanner.
The profiles are created using the sets of pictures taken with
particular optical system and the reference picture. For example, for
generic cameras it is possible to display the reference picture on a
monitor and take shots of it by the camera being profiled.

For the scanners the question is - whether it is possible to create a
'reference slide'. If the resolution of a slide is determined by a
film - it is possible to take a photo of the sample picture and use it
as the reference slide. But if the resolution is determined by the
camera optics - the profile will be created not for the scanner but
actually for the combination of scanner + camera + lens.
Of course, it is possible do the following - take a photo of the
sample picture, use it as the reference slide, create the profile and
then try applying the same profile for the slides taken with other
lenses.
Another possible way: scan the reference slide with a scanner that
has much better resolution than the target scanner (four or more times
as much) and then use the high-resolution scan as the reference
picture. We mean effective resolution, of course, so if your scanner
gives 1800-2400 dpi it would be enough to use the one giving 4800 dpi.

We are ready to experiment with scanner profile creation if you can
provide us with necessary sample scans. As this is to be an experiment
- we will do it at no cost.

Sincerely,
PhotoAcute Support
