How do I use NegaFix with a 48 bit scan. If I try to scan in 48 bit I still get an orange scan. The only way to get NegaFix to work is with 24 bit. What am I doing wrong?

To use NegaFix on 48 bit images you need SilverFast HDR. SilverFast Ai only allows editing of image in the 24bit output mode. Once you choose 48bit mode you disable all the editing tools. Unfortunately it would appear that this doesn't extend to disabling the NegaFix dialog and tools and so the poor user is left tweaking away and yet knows nothing about the loss of these tools until too late I think this is something that needs fixed.

On a more positive note - if your version of SilverFast Ai has 48bit mode available then your 36-24 bit mode was already working on 48bit mode images.

When I scan reflective documents, I have both 36 to 24 bit and 48 bit options. If I scan in 48 bit, I am unable to use the software image adjust features, but I think I get a better scan. I then do my tweaking in Photshop.

As I understand the reply, unless I have the HDR version I will be unable to 48 bit transparency scans. If that's true, how do I get the HDR version and is there an upgrade cost?

I guess I'm still unclear. I have an Epson Expression 1680 scanner. It will do true 48 bit scans. Silverfast came bundled with it. Through trial and error I saw superior results when scanning in 48 bit mode and adjusting in Photoshop, when compared to scanning in 24 bit and using the image controls in SF 5.

When the 5.5 upgrade came out I upgraded my SF Ai software, not understanding that HDR was a different program. Can someone advise me as to what softare I should have?

Does this mean you are the individual wo raised the original question or just someone with a simliar problem. Anonymous is Soooooo impersonal

You can still do that if you wish

Your scanner supports 48bit modes scans an SilverFast in 36>24 bit makes use of this output (interrnally). Why not try it and see of it works to your satisfaction. HDR allows you to do little more with the image than Ai, except that your edits can be delayed until a later time. The output from HDR will still be 24bit colour

So with Ai you can prescan and edit images and output as 24bit colour or you can scan 48bit colour images but will need to edit in Photoshop or HDR

48 bit output is mandatory!!!

I tryed to use SilverFast for a long time. Automatic processing of negative films is quite good if the negative is in the average. With bad negatives or slides, the result with Epson TWAIN Pro and Photoshop is MUCH MORE BETTER. I can recover images that with SilverScan result in very bad quality. Anyway to have the output on 24 bit is not professiona at all. I dont spend money on a 14Bit/color scanner (EPSON 1680) to reduce it to get just 8bit/color. In facts, if one have to perform some post-processing on the image, 8bit are not enough and the resulting quality is very poor.
