Custom manufactured APS film holder for Epson Perfection v100,v200,v300,v330,v370 flatbed film scanners (Patent Pending).  Some of these Epson Perfection models came in regular document scanning models while others (using the same model number) also functioned as film scanners.  This holder will only work with models that are designed to scan film.  Such models typically had "Photo" as part of their model name.  The sure way to know that you have such a model is to make sure you have a second light source in the lid of your scanner that allows for scanning film.  This was CAD designed and manufactured for use with the obsolete Advanced Photo System (APS) format that was very popular over a decade ago.  Marketed by Kodak under the name "Advantix" in 1996, the format became instantly popular.  Both Kodak and Fuji stopped manufacturing APS film in 2011.

Unfortunately not only is it almost impossible to get prints made from APS film these days, but APS negative holders are hard to come by and the ones that you can find cost upwards of $100.  Additionally, while many film scanners allow for negatives to be scanned directly on the glass, APS presents a special issue because it's stored wound tightly inside the film canister.  Once you get it out of the canister, the negatives roll in to a ball unmercifully without something to hold them flat.  Removing exposed negatives from an APS canister is actually quite easy.  You literally break it out any way you can.  Since APS canisters are plastic, I use a pair of pliers to gently crack open the canister to gain access to the negatives.  If you don't want to destroy your APS canister, there are commercially available products known as "film retrieval tools" that will work for APS.  I am also told that it is possible to use a small flat screwdriver to open the canister film door and then use the screwdriver to turn the canister center spindle to make the film eject for scanning.   

Please be aware that aftermarket film holders such as this require the user have the ability to scan in manual (sometimes called "professional") mode and will require individual masking/cropping of each image (or the entire filmstrip) for scanning.  Automatic image detection and/or thumbnail mode will usually not work on such holders unless you're using a higher end aftermarket scanning program like Silverfast.  Please make certain you have appropriate scanning software that will allow for this level of user control.
