Digitizing my diapositive slides with my A7

For a couple of years I have been thinking of digitizing my diapositives. I have several thousand slides from the 80ies and 90ties pluss older family slides from 50 years back. Having it done professoinal is really expensive so I tried with different methods. a couple of flatbedscanners was tested, but it took a long time, created large files of not optimal quality. I found that it also focus just at the glass scanner surface so any dust there were very sharp, whereas the dias not always was.. so i bought a simple Soligor diasduplicator t42 to minolta and hooked it to my Sony A7 with a minolta to sony E adapter. It kind of worked but it was cumbersome and time-consuming to change slides and check focus for each slide. It also has a single glass lens of unknown quality and no aperture obviously. I didnt bother with this either. The final solution was to use a macro lens with 1:1 magnification, so I got a used Tamron 90mm f2,8 AF for Sony and used it with my LA-EA4 adapter. I made a very simple lightbox from a 4€ Perspex plexiglass (white acryl) and a 30 $ battery powered videolight with 160 led lights. Put the lightsource in a box with the perspex as a lid and used a macro tripod to get the 90mm in correct position above it. I taped a corner of perspex bits onto the lightbox so that the slides could be placed easily in right position. It takes only a few second to place the slide, a two second wait for the self timer and then the exposure, so many slides could be done quickly. I then used the play memories app Remote controll on my iPad to check exposure, focus and placement of the slide. This worked very well. I chose raw plus jpeg in the app and then i got instantly jpeg saved on my ipad and at the same time raw and jpeg on the camera card. it was very easy to digitize slides this way, i could make 100 slides in about 10 minutes! The camera was autofocusing or i could use manual with focus peaking. Adjusting exposure and white balance was very convenient from the ipad. Quality was at least as good as my scan- test and acceptable for me. nice to see the old pictures that was hidden away for so many years!f7b883ed68fa1d694fa3f42a60ab5dcb.jpgcde9f0a347035ba9cf45f69515d68f78.jpgd4efb74226d894002637d2f6a7b7625d.jpg547620b6695687177e340b182383dfac.jpg

Hope this can inspire others to use their fantastic A series digitizing machines to recover old treasures from cellars and cupboards where they hide.467019d5bc3a0bd2739133db92ea0458.jpg

This is indeed a very good solution! I did it in a similar way, using my A7r and a 100mm Contax-Zeiss Macro lens - but i did not have the idea of using the Play Memories app on the iPad!

Have a look at some pictures of my solution, sorry for the text being in german: http://thomashofinger.at/2015/04/25/filme-digitalisieren-ist-nicht-schwer/

Hi

Here is my solution :

Sony A7II, Zuiko 50mm f1.8, filters frames and/or step-up filter frames, a high power led light mounted into a wooden box, with an on/off button.

It remains the most hassle part of the job (Photoshop) : framing at the right size, removing dust particles, giving the true colors, ...

Hi,

 

has anybody something similar for negative film? How to "exchange" the colours - all the rest is available for me too... ( MAF 100/2.8 rulez! )

Thx,

Peter

      ISO Bracketing

      By popeye10 · Posted

      Thank you XKAES  and Pieter for responding to my query. Since my post, I figured out what I was doing wrong, and now I am getting more predictable results. To answer a few questions, I am using a Sony A7R5, and am aware that it is ISO invariant, however at least for what I've tried, there are limits to how much you can "push" exposure in post. I am doing some night/astrophotography and when I set iso to 400, and increase exposure in post, I get more noise in dark foreground areas than if I use a higher iso in camera when I increase exposure 4 stops or more. I wanted to do iso bracketing so that I could further compare the results and choose the settings that gave me the best results. I had hoped that I could set the minimum iso to 320 and take 3 or more images at 2 stop increments, but I now doubt that's possible. Since the camera is choosing iso based on the light it detects, it may or may not start at 320. Any thoughts or suggestions would be appreciated.

      Video files won't transfer

      Thank you @Cameratose. I have tried Shotcut and it seems I can work with the video. I still don't understand why this works and yet iMovie does not. But happy to have a work around and I will keep learning. Thanks for your help.

      ISO Bracketing

      By Pieter · Posted

      Out of pure curiosity: why would you want to shoot a bracket using ISO as your means to control exposure? Sony cameras are virtually ISO invariant (save for the second gain step), so raising ISO in camera or in post-production yields nearly identical results. Most people shoot bracketed exposures to gain detail in over- and underexposed areas, but when you use ISO as your exposure variable, you might as well just create the bracket in post by raising/dropping exposure. You don't gain any dynamic range that way.
