Re: Film scanner vs digital camera - biological/geological thin sections
As it appears the Optiscan10 is another specialized version of the Pacific Image entry level scanner (seems to be discontinued, no longer listed on the Pacific Image/Scanace product page?!), hardware adapted to the current 10K resolution Pacific Image product line. USAF 1951 resolution forum discus...

Re: Film scanner vs digital camera - biological/geological thin sections
Sorry for being late for a while. Currently, I'm doing my scans with the OpticFilm 8200i scanner. I want to increase the quality and the resolution of my scans. Recently I saw the OPTISCAN10 scanner on the market, and it is in my budget (no more than 1000 euros). There is anyone here on the forum wi...

Re: Film scanner vs digital camera - biological/geological thin sections
Dear Micha and Hermann-Josef, Thank you for the technical corrections, I have attached two scans, one @3600ppi and the other one @7200ppi, both of them with HDR settings without any post-processing in Camera RAW/Photoshop (e.g. sharpening, contrast, shadows, etc.). I've just saved them to jpg format...

Re: Film scanner vs digital camera - biological/geological thin sections
This will only work if your sections are transparent to IR-radiation. Indeed. Many scans are made on transparent thin sections. -- I've finally tested the OpticFilm 8200i with SilverFast AI. I've got very good results. See attachment for a small piece of microscale glass (the smallest unit is 0.1 m...

Re: Film scanner vs digital camera - biological/geological thin sections
Regarding the PrimeHisto scanner, I've contacted different customers, and I cannot find it in Romania. Even in Europe, just one website from Germany, but they don't respond to my quote/request. I think the price and what it's offer is a good option! Thank you for telling me about the PrimeHisto. I w...

Re: Film scanner vs digital camera - biological/geological thin sections
Sorry for being late with my responses, I attached a schematic overview of my sample. As you can see my area of interest is ~ 30 x 20 mm. The sample glass can be shortened or I can trim the plastic slide mounts one normally uses for 35mm film. Somehow I can make them so that the thin section would s...

Re: Film scanner vs digital camera - biological/geological thin sections
Dear Hermann-Josef, I read the whole Film scanners tests (except low-end film scanners). Also, I looked at different websites where the film scanners were used as WSI (Whole Slide Imaging) system. I know that this comparison is a little bit forced, but I'm wondering if I can get better image resolut...

Re: Film scanner vs digital camera - biological/geological thin sections
Dear Jossie, Thank you so much for your response. The thickness of the rock is ~ 0.03 mm/30 microns. The slide itself is ~1-2 mm, but if the film scanners can focus on the thin slice of the rock is great! I have enough depth-of-field. Regarding the digital cameras, thank you so much for the info. So...

Film scanner vs digital camera - biological/geological thin sections
Hi there, I want to scan some thin sections/slices with geological or biological features. Currently, I took the photos with a digital camera (5D mark-iii) and a macro lens (100 mm 1:1 magnification). The output of my photos is at 5760 × 3840 pixels at an effective resolution of 22.3 mega pixels. My...
