It does look sharper

Is that 4X the data file to achieve it?

Heidelberg Tango Drumscanner | Newcolor 2000 MAC | Kodak Portra 160 Color Negative 16 BIT TIFF

The best ColorPerfect conversion I could achieve without increasing saturation. LINK TO 5000 DPI FILE

Hi Randy, which scanner/scan were you asking about?

**Tin Can** · 20-Jan-2019, 16:35

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!

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.
