SRDx, USM etc. not available while scanning in 16 bits HDR

Postby aurelienpierre » Sat Dec 17, 2016 2:14 am

Hi,

I'm using SE Plus 8.8r6. With the previous version, I was able to scan negatives in 16 bits/channel while applying corrections like USM, GANE, and SRDx. Since the latest update, all I can do in so called "HDR" (16 bits is really not a true HDR) is multiple exposures. I have to switch back to 8 bits/channel to enable these features.

Is that a bug or a feature to force me to switch to SE HDR Studio ?

Dear User,

SilverFast SE does not have the capbilities to create processed 48 Bit images. This feature is only available in Ai Studio.
This has never been different.

Kind regards,
Arne

Hi Arne,

Until August 2016, I was able to produce 16 bits "HDR" files and apply corrections on them directly in SE Plus (GANE, iSRD, SRDx, etc.) which was nice. I have the TIFF files to prove it. It's a disapointment to have to constantly upgrade the software to get access to the core functionalities of the scanner (namely, the 16 bits output + the IR channel + the multi-exposure at once), especially as it ends up with a piece of software redundant with Photoshop or Lightroom (but significantly less efficient and user-friendly).

All I would like to do is to produce a clean color neutral 16 bits RGB scan on which low-level corrections using the scanner features as been applied (like the IR dust removal, multi-exposure and film color calibration), then send it as a 16 bits RGB TIFF file to Photoshop or Lightroom to perform higher-level edits just as every digital RAW file from modern DSLR. Some functions in Silver Fast are redundant with Photoshop (curves, contrast & color adjustments) while some basic others are missing (IR channel processing on 16 bits output files - the scanner outputs 16 bits anyway), and apparently I need a software to do the data acquisition and another one to do the data cleaning.

Silver Fast should act as a meta-driver which produces the equivalent of a digital RAW picture (taking care of all the technical corrections specific to the film medium at once) and output a regular lossless file that every picture editing software will understand. I need Silver Fast only to communicate with my scanner and to do the film cleaning, I have a better software to adjust brightness, hue, saturation, contrast, etc. and do the printing. This forces me to have a different worklow for digital and for film photos and basically 2 software licences to do the same things. I'm not happy when I have to pay twice for the same service (and have to use Photoshop anyway for selective editing with clever masking options).

Why I have to use 2 of your software to perform this single task sounds to me like a trick of your marketing department.

Dear user,

raw data and processing is a contradiction. Raw data is defined by being unprocessed.
You can either create unprocessed HDR RAW files or processed ones.
In SE Plus you can only create 8Bit per channel files when processing.

Kind regards,
Arne
