 +====== Negative scanner ======
 +
 +This guide will be based on using the following Camera equipment:
 +  * Canon EOS 40D (but any Canon APS-C sensor size camera will work)
 +  * Tokina 90mm f/2.8 macro
 +
 +===== Inspiration =====

 +
 +[[http://www.johnamon.com/2010/08/how-to-copy-35mm-film-with-dslr-camera/]]
 +
 +===== Equipment =====
 +  * 55-77mm step up ring [[http://stores.ebay.com/jiakgong-DIGITAL|Jiakgong]] (ordered)
 +  * 55mm pol filter (we only need the ring) [[http://stores.ebay.com/jiakgong-DIGITAL|Jiakgong]] (ordered)
 +  * 75mm PVC drainpibe
 +  * Dias film holder (getting a bunch from my dad)
 +
 +===== What to do =====
 +  - remove filter from filter ring
 +  - calculate/measure length of PVC pibe to give a full 35mm film view (it's better to crop in software that to loose image)
 +  - cut PVC pipe to length
 +  - mount PVC pibe to the step up ring on the 77mm side
 +  - mount dias film holder to opposite end of PVC pibe
 +  - mount the pol filter ring between the lens and "scan unit"
 +
 +At this point we are ready to go and just need some proper light and a few solutions may work:
 +  * LCD screen (laptop, tv or whatever)
 +  * soft box
 +  * ...
 +
 +===== Measurements =====
 +35mm film strip at 15,20 and 25cm
 +
 +{{:projects:photo:01-15cm.jpg?200|15cm}}
 +
 +{{:projects:photo:02-20cm.jpg?200|20cm}}
 +
 +{{:projects:photo:03-25cm.jpg?200|25cm}}
 +
 +I'd say around 18cm tube will do the trick - the pol filter ring and step up ring will also add a little distance...
