Re: Scanner Comparison 2019 [Epson Flatbed | Eversmart Flatbed | Drum Scanners]
It does look sharper
Is that 4X the data file to achieve it?

Hi Randy, which scanner/scan were you asking about?
Re: Scanner Comparison 2019 [Epson Flatbed | Eversmart Flatbed | Drum Scanners]
The last one. Never mind, i am downloading all of them.
Keep it coming!

Human eye may see a bit the individual lines in Group 1.
Group 2 have lines of around 0.05mm thickness. Whe can see a hair that is 0.07mm, but if two hairs are separated by a hair width then we see a single hair.
In Group 6 lines are around 0.005mm thick.
.005mm is 5 microns, or about 5-8 waves of light! Probably can't inexpensively scan or capture visible light much better than that.

This is the same comparison area from all three drum scanners with AUTO COLOR ( CTRL + SHIFT + B ) command. They are all sooo close :)

Excellent point JP!
Re: Scanner Comparison 2019 [Epson Flatbed | Eversmart Flatbed | Drum Scanners]
Phew - round 1 of the tests is complete across all scanners! This will take a while folks and I hope you are all on-board for a long ride. What should I go with next - slide or black and white negative? I'll pick a 4x5 photo this time.

Yes, good point !! we approach to visible light limit wave length, anyway because of light wave lenght still we have room before it starts being a limit, microscope targets end in group 11, group 9 or 10 are usually seen with regular bio microscopes.

A Nikon D850 has a pixel size of 4.34 microns...
