Some of the photos from the older Canon A710 IS camera were taken in raw mode. How's that done? By using hacked firmware, of course! Here's a link: Camera Hacks at Lifehacker
Early 35mm scanning was done with a Nikon LS-1000 CoolScan. This unit has LED illumination and 12-bit A/D converters. There's no backing scratch it couldn't resolve! Medium format images were scanned on a Howtek Scanmaster 4500 drum scanner at from 500 to 1000 dpi. The drum scanner uses incandescent illumination and photomultiplier image pickup tubes. 12 bit-A/D conversion is done following an analog log conversion stage. More recent film scanning is done with an Epson Perfection 4990 Photo scanner. These days I have access to a Hasselblad scanner, but I no longer shoot on film.
Adaptive unsharp masking image enhancement was applied using the GIMP (Gnu Image Manipulation Program) under Linux and the image was saved as a JPEG. A thumbnail version was also saved for the clickable images on the gallery pages.
The newer photos are processed using Adobe Photoshop Lightroom versions 1-4 and CC2015 on Mac OS X, in some cases followed by final touches in Adobe Photoshop CS5 or CC2015. ImageMagick is used by the web server for automated image resampling on the newer photo galleries.
