I have been working on digitizing some old Super8 home movies for quite some time. I have gone through a number of hardware iterations with varying degree’s of success. I am currently using a Bell and Howell projector that I have modified with a stepper drive and LED lamp. I really like what I am seeing here with the design of the Kinograph. My question however is with regards to capturing all the information on the film frame. I am as interested in preserving the film frame as wella as producing a digital version. I have researched the characteristics of Super 8 film and found conflicting information with regards to resolution and dynamic range of the stock. I do know that a typical digital camera can not capture the full range of a film frame in one shot. I am using a Point Grey Flea USB3 machine vision camera. ( 3 megapixels, 12 bit ADC) with a macro tube extension and a 50mm nikon lens ( what I have on hand). I have been experimenting with using HDR to extract more information from the frame. I have experimented with taking up to 10 bracketed frames and then used LuminanceHDR to combine them into an HDR file. This has sometimes resulted in spectacular results and other times terrible images depending on the particular reel I was processing. So I have recently changed my approach to capturing RAW bracketed images with the intent of creating a good processing pipeline to create the final digital frame. I intend to archive the digital frames in whatever format can preserve the most information and use that to produce the digital video.
Having said all that, has anyone else explored this area in terms of faithfully capturing all the image information in the frame. If so any input would be greatly appreciated.
