High Bit Images
I am using SilverFast HDR to edit high bit images (48 bit) created with the Polaroid SS4000 and SilverFast Ai5. After editing the image in SilverFast HDR and transferring the image to PhotoShop the image shows up in PhotoShop in 24 bit mode. Is their anyway to do color corrections in SilverFast in 48 bit mode and transfer the image into Photoshop in 48 bit mode for additional editing?

I can't believe the last post to this topic was in August 2001!
Silverfast Ai (and/or) HDR needs 48-bit output, like, yesterday.
HDR should be an optional tool used solely for post-processing batch scans. As it stands, it is a flawed tool because it doesn't export to Photoshop in 48-bit mode for further tweaking without information loss.
Ideally, Ai should have all (or most) of its tools available when scanning in 48-bit mode. We shouldn't have to 48-bit scan in Ai and post-process in HDR ("the Silverfast two-step"). For what we paid, we should be able to adjust 48-bit scans in Ai, and export to Photoshop in 48-bit mode. That way those of us who poke along, working on one image at a time, can have real choices that leave us with 48-bit files optimized pre-scan in SF, and post-scan in Photoshop. Job Manager could be used to set up a very sophisticated batch scan, in which each image is individually optimized, then exported to Photoshop in 48-bit mode.
All of the above would be especially nice for those of us still working with Live Picture 2.6.2 AND Photoshop 6.0.1.
Here it is, nearly February 2002, and I'm still doing unedited 48-bit scans with Silverfast. Yes, I have the Ferrari of scanner drivers, but the governor on the engine only lets me do 24mph!!!

A lot of people seem to work with photoshop in 48 bit mode. I have difficulties to do so. When I export my scanns from silverfast Ai (uncorrected) as 48 bit images and view them in photoshop, they are allways very dark. I thought, photoshop would expect a range of 16 bit per color, whereas my scanner gives only the least 12 bits of them. Please can anybody explain, what is the trick to view these images with photoshop?

In SilverFast press the Option button and choose the General Tab. Towards the bottom you will see a facility for altering the gamma gradation. Set it to around 2.0 and ensure that the little checkbox. to the right, i.e. "for HDR output" is checked.

Thanks for your answer Ian!
You ?ve been right, I missed the checkbox. But I find it a little bit disapointing, that photoshop is not able to view the raw data. (The tiff-file contains information, how many bits are relevant.) One the other hand, I dont understand why the scanner manufatures dont align the MSBs (=most significant bits) and leave the not needed LSBs unused (zero). This would work for every number of bits of scan resolution without special actions by the software. But might be, that this would be too simple.
