In case you haven't seen Ellis' excellent review of the Epson 750 scanner:

Thanks for the link, Kirk. I always enjoy Ellis' observations as well as his writing style.

To be honest, though, I'm hesitant to read the V750 review, lest I discover I shouldn't have purchased one.

Very intresting. However the major point of annoyance for me is rasied again b/c the reviewer keeps talking about medium format negatives. I wish there was a review that talks specifically about scanning 4x5 slides.

It seems like medium format provides a more demanding test, because it's subject to a greater enlargements. Ellis's article addresses fluid mounting. In that particular case, everything that applies to medium format would also apply to 4x5.

Is there some other aspect of 4x5 scanning about which you want to know?

Well i've been intrested in this scanner for a while now but have been put off by the prospect of doing fluid mounting. So much so that i have been waiting for microteks latest offerings and see how they compair. I guess it didn't occur to me that medium format will provide a more sterner test for the scanner. I am just curious to know if i can get away with doing a regular dry scan for prints about 16x20 using 4x5 transperencies.

That depends on your expertise and expectations. For me no.

Hi guys,

According to this comparison done by Aztec products, the wet mounted scans with the 750 are actually sharper done directly on the glass than on the fluid mountin bed:

Any comments on this? I'm planning on doing wet mounts with my 4990, and based on this, was going to do them directly on the glass, but I was concerned about it not being the optimal plane of focus.

[Kirk Gittings]

I was concerned about it not being the optimal plane of focus.

Sandy King have discussed this quite a bit. While there is an optiml plane of focus, given the lens design, there should be huge D of F. Yet the difference of a couple of mm seems to make a big difference. The larger the film size of course, the less difference this optimal plane matters in the real world of a final print.

There are all sorts of fluid mounting and several different commercially available mounting fluids. There are two main purposes for fluid mounting: 1) to maintain the flatness of the film and keep it flat during the scan and 2) to 'fill in' scratches or other flaws on the film. Any of the commercial fluids will take care of 1, OTOH if you also need to deal with a lot of scratches then you need a heavier fluid. For most of my scans I find that the lightest, easiest to apply fluid from Prazio, their 'anti newton ring' spray is all taht is needed ... it is easy to use and maintains perfect adherence and is dead simple and quick to clean up.

Ted,

Do you need to sandwich the film, or do you just stick it down to the glass with the Prazio spray? I have been curious whether sandwiching is necessary for flatbeds, as it is for drums.
