All my images are recorded onto raw files and are often under-exposed by one stop. This is done to ensure that sufficient detail is recorded in the highlight areas with one eye looking towards the production of the prints. If the shadow areas become a little dark they can easily be adjusted in the computer but detail not recorded in the highlights is gone forever. The images are opened in Nikon Capture where some image adjustment is usually made and then exported to Adobe Photoshop for the final production.
Before any work on the image is done the final print size is set and the ppi is interpolated to 300, although currently with the Nikon D3 body images are captured at that quality. When the image looks close to being complete a test print of a section is done at correct size and if necessary further adjustments are made. The final test prints are of the whole image and as many as necessary are made until I am happy with the image.
Once the work on the print is complete it remains unaltered and the edition is printed. I have always used Epson printers to print my limited edition prints and currently I am using the Epson R2400 printer which uses pigment inks giving the prints archival properties. To ensure that those archival properties are sustained they are currently printed on Hahnemühle Photorag paper which is acid free (the presents of acids will have the effect of fading colours over a period of time).
