Vuescan w/Plustek 7600i

[egor]

Question for those of you who use the *specific* combination of VueScan Pro (latest version) with a Plustek 7600i:

Is Vuescan's multi-exposure setting (NOT the multi pass setting) working correctly for you?

On my Macintosh (Mac Pro), it's definitely not working. It *looks* like it's working. That is, the first pass (which I watch in Vuescan) is at the 'normal' exposure, and the second pass uses a much longer exposure (as expected). The problem is, when Vuescan merges the two exposures, I end up with a TIFF file that's *exactly* the same as a single-exposure file. You can even overlay their histograms -- they're identical. It's like Vuescan is simply throwing away the second exposure, rather than merging the two.

This is a big problem with the Plustek 7600i since its D-max is so low. When scanning full-range B&W negatives, I get severely blown highlights. I can *manually* make two separate exposures and combine them in Photomatix, but that's a huge hassle -- that's what the Multi Exposure option is supposed to do.

I've been using VueScan for 9 years, and a zillion film/slide/flatbed scanners before this. First time I've seen this problem. Haven't heard anything from Ed... so I thought I'd find out if anyone with this combination has had any luck?

Note: I just 'upgraded' from a V600, which rendered gorgeous tonality from the entire B&W negative -- but was too "soft." So far, scans from the 7600i are much 'sharper' (at least on a grain level), but fail miserably in the highlights (dark areas on a negative)...

Did you ever get the multi-exposure working?

This scanner looks great, hopefully Ed got round to fixing his software...

I bought the scanner yesterday, and it works for me. I'm using an Imac. You just have to make sure you use the 32-bit version of Vuescan to be compatible with the Plustek driver.

This scanner is not very high quality, and the SE version of Silverfast does not allow both multipass and multiexposure at the same time, but Vuescan does. Multipass is essential, because this thing creates a ridiculous amount of noise in the shadows. I used to have a Nikon 9000, and that was really bad, but this is just absurdly bad.

I think I'm going to keep it for quick blogging and such things, but real scans will still have to be done on an Imacon.

I should add, that I've had registration issues when using both multi options in Vuescan. I'm continuing to test this, but it looks like Silverfast does a better job of it.

Where are the multi-pass options? I can't see them at all. I'm also using the 7600i with Vuescan.

I'm not sure, but I think these are the settings for Vuescan.

I still want to learn how to use SilverFast because it looks like it has a lot of capabilities, but I'm used to Vuescan so tinkering with that for the time being.
