Negative nor corrected in HDR studio (demo)

Postby fjribes » Sun May 29, 2016 3:27 pm

Hi,

I'm trying out the demo version of both, SilverFast Ai Studio and HDR software packages.

My problem is that in HDR studio, negatives do not show with correct colors. It seems as if the compensation for the orange hue is not been applied. This is what I do:

- First, I scan in SilverFast Ai Studio with options Negative and 48 Bit HDR. The file is saved as Untitled.tif.
- Then, I open Untitled.tif in HDR Studio from VLT. It opens as a negative, but it shows a green cast. Interestingly, if I switch between negative and positive pressing alternatively Ctrl-1 and Ctrl-3, I can see the correct colors when entering the Negative mode, but only for a fraction of a second. After this instant, the image is again shown with the green cast.

Am I missing something in the procedure? Is this happening because it is a demo version?

I'm using a Nikon LS 50 / Coolscan V scanner. I'm running:
- SilverFast 8.8 DEMO. Version 8.8.0r4. Build number: 16874. NIKON LS50 Filmstrip
- SilverFast 8.8 DEMO. Version 8.8.0r4. Build number: 16874. HDR Studio
- Windows 7 Professional. Service Pack 1.

These are captures of both, the scanner and the HDR programs, processing the same negative:

Dear Javier,

This happens because of the watermarks the demo puts into the image.
In a full version the image would look the same as in the Ai Studio software.
On our demo download site we offer HDR RAW images for testing because of this.

Kind regards,
Arne
