First fluid mounted scans...question

[John NYC]

When you did your tests did you, 1) make sure that film holder was selected in order to engage the highest resolutions lens, and 2) did you determine the best plane of focus for that lens? If you were to use the lens that is engaged when film area guideis chosen you would not get better than about 1600 spi - 1800 spi.

Of course, the difference between 1600 spi and 2300 spis is not all that great if you are comparing real negatives. To observde a difference that small might require testing with a high resolution target.

1 = yes
2 = Edit: Wait, I get what you are saying now. Unless the film holder is used, you will only get 1600-1800 ppi. So my 8x10 experiments obviously don't matter. For MF film, yes, I used the film holders. I will try with all the alternate heights, but I am getting sharp scans so I never messed about with that. I will repeat the experiment with MF format film and all heights when I get some time.

In my tests I definitely a very small improvement scanning negs at 3200 instead of 2400 with an Epson 4870. Anyway, it is sooo small, it really doesn't matter. I am not too crazy about Epson flatbeds, at least with mine.
