Hi,
I have just done some test scans with the demo version of SF Ai & SE. I scanned a color negative slide with my epson perfection 1240U, and, SE took, with the same settings, exactly DOUBLE the amount of time as Ai to scan the frame. Is this normal? I thought SE & Ai are essentially the same programs, with one just having more options than the other.

<B> Speed differences
Ai and
SE
SilverFast
SE can be so much faster because very complex functions have not to be processed during the scan such as Color Management and more complex Selective Colour Correction.
These functions take up huge amount of processing power.

Hi.
you misunderstood me, it was actually Ai that was twice as fast.

Dear Martin,
could it be that you used SilverFast
Ai as Photoshop module, but SilverFast
SE as TWAIN module?

I've received the same results with my bundled version of SE compared to the AI demo. I actually timed the scans at 2400 DPI from SE, AI and the Epson twain (I have a 2450 scanner) and SE took 7:55, AI 3:25 and the Twain driver
6:10. The settings for both SE and AI were the same. I'm using them as photoshop plug-ins, not twain. Any particular reason for this discrepancy (like features being stripped from the demo making it faster), or does the more expensive package feature a speed jump?
On a related note, I've been thinking about upgrading to AI, but I haven't been able to figure out how to do it on this website without ordering it from scratch and having it shipped to me, which I don't want to do. I have to start hiding a few expenses, or my wife will start spending more. What a frightening thought!
