I'm going through some of my better old pictures and rescanning and reprocessing them with some of my latest techniques. Some of you may know that I like to do this sort of thing from time to time.

My current refinements are to do with utilising the open source ImageMagick libraries to manually manage the use of calibration profiles that I previously made using Vuescan and some high quality IT8 film targets. I am still doing the actual scans as raw linear using good old Nikon Scan 4. I manually apply the profile afterwards and convert to my working space. This gives me full control and no surprises.

The other technique involves a piece of software called PhotoAcute. It's trick is that it can take multiple photos of a single scene and work out a higher resolution version of the same scene. The trick is that the camera will always move slightly between shots. Therefore the pixels from one shot will occupy the space between the pixels from another shot. With enough shots the software can work out what a higher resolution sensor would have seen. It is intended for digital photography but seems perfect to me for improving the quality of my scans. I simply make multiple scans and feed that to the software.

This particular shot is of the plaque outside my work. It was shot on Fuji Velvia 50 slide film using my Nikon F4 and Nikkor 50mm f1.4 AF-D lens. It dates back to the summer of 2010. This one is sharp enough to cut yourself on so be careful!
