Digitizing 35mm micro photography tranparency images

#1 Post by MicroBob » Sun Nov 24, 2019 11:04 pm

Hi together,
we are about to collect stuff from an old member. There are probably about 2000 well selected microscopy images on 35mm transparency film. To make this wealth of high quality images available to the public we will have to get them digitized. Due to the amount individual handling is out of question and funds are limited too, as usual. The goal would be to get images of medium quality (e.g. 4MP sharp, colourful, well illuminated) images for an acceptable price.

Does somebody have experience with digitizing companies with work on micro images? In my experience micro images are not always handled right by camera exposure control, so automatic scanning might lead to bad results.
I found a digitizing service here: https://www.ebay.de/itm/1000-Dias-digit ... 3149507796
The price would be good and the scanner in use might be quite ok from what I read.

Is that EUR 79,17 to digitize 1000 slides? Has to be automated!

I would contact them, get a phone number and explain what you need.

Hopefully they may be willing to redo any that you consider did not come out right.
Zeiss Standard WL (somewhat fashion challenged) & Wild M8
Olympus E-P2 (Micro Four Thirds Camera)

Here’s a fairly detailed review of the Reflecta DigitDia 5000 [which appears to be what they use]

I digitised 300 family 35mm slides with a DIY setup of diffused flash/DSLR/macro lens/and slide mount. The results were acceptable but the biggest hurdle was ensuring the slides were clean and dust free beforehand. If not stated in the eBay service listing (sorry don't speak German) I'd enquire about slide preparation, or if this is something that needs doing in advance.

Hi together,
thank you for your replies!
The digitizing service I linked writes that they clean with compressed air. For loose dust that will do. When I have the slides I will see how clean they are. Scanning is probably affected by frame type and glass/antinewton glass/glassless too.
I had sent 35mm negativrs to another digitizing service and got film and results only back after making preparations for taking legal steps. :evil: So this is also very much a question of dependability of the service.
For my own negatives I plan to do the digital copying myself, the equipment is about to materialize soon. But this is a time consuming process.
If I would start to do that with the group members micro slides, my wife would probably throw diatom material, paraffine and canadabalsam in my dinner until I realize that this is not a welcome pasttime in her eyes. :lol:
