When a film is professionally scanned in 16-bit color as DPX image files, every single frame weighs in at 100 MB. With upwards of 175,000 frames in each film, a complete scan requires about 21 TB of storage (42 TB if you want a backup copy! And then you need at least another 21 TB of space to work on it – over $1000 just in hard drives is therefore required for every film). Having the film cleaned prior to scanning costs another $870 (plus about $75 shipping each way) and then the scanning costs between $2000 and $15,000, depending on where you send it.
Now, I would very much like some information on the scanning process of these films and the machinery used and whether or not they where cleaned up. Cheers!
