Scanning XPan - Tested

Sounds good, I'm still pondering about which one I should buy.

If you can afford it, I think the 5400 is a lot better than the Dual IV. It's not just the resolution. The increased dynamic range is very useful. I mainly use Velvia for nature/landscapes, and find that the 5400 is capable of reproducing different tones in areas that came out black on my previous scanner (Dual III). Reliable sources tell me it is also better for B/W.

The original 5400 was recently replaced by an improved version (it is much faster). There are good deals available on the earlier version. If you scan at the same resolution and bit depth as is available on the Dual IV, the scan time is similar.

So, my advise is to go for the new 5400, or the older version if your budget is tight.

Thanks for the info, I think I will be getting at 5400, it's just the sneaking it passed the wife bit ;)

How big is a maximum resolution file when merged? Would you be able to post one? (it doesn't need to be a great picture, I just want to see if I can spot the stitching)

Thanks!

I am posting fom the office today, so I'll try to attach an image when I get home.

A 24x36 slide is about 200MB (TIFF) when scanned with 16-bit and max resolution.

So for a full res, 16-bit Xpan scan the merged file is approx 350MB. Half of that for 8-bit of course. I have 2GB RAM in my system... :D

Here's an example of left and right parts merged automatically in Photoshop with considerable overlap, in which the merged parts had different scanner exposures. Just learned how to do the merge, but obviously I need to learn how to get the densities to match too!
 
Hey Otto - any chance you can somehow post a large sized scan??? maximum JPG compression is fine, I just want to see if I can see the join!

Thanks
 
I use to have to do this with my old 4000ED. Now I am running a 9000ED with the rotating glass holder and it is a lot easier. I use Silverfast Ai Studio and it is killer.
