Looking through some old scans recently, I came to realise the the unique quality of colour transparency film, and its ability to record huge amount of information - even in 35mm; easily a match for a 24mp DSLR. Sadly, few choices still remain for this type of film as Kodak ceased manufacture of E100G, their last remaining E6 film, in 2012. It can be easy to forget that transparency film was the medium of choice for advertising and editorial photography for decades, at least until the 1990's, when colour neg film became more popular. My message is simple; make the most of it while it's still available, as a few years from now it might not be.
Kodak's Ektar and Portra colour neg films are great films to shoot on for digital output as they are designed to be scanned; for anyone wanting the permanence of analogue film they also offer the ability to respond well to retouching and enhancing in Photoshop. Despite film processing and scanning costs, which can be kept relatively low, there are clear advantages to a 'hybrid workflow' as it is sometimes known. Nikon's remaining analogue camera, the F6, has the ability to generate EXIF data for every frame, which is recorded on a memory card and downloaded via the MV1 reader. It is therefore possible to have a fully functioning digital workflow for analogue images, if desired. Judging by the incidences of data loss that I have come across, having the originals in material form makes a huge amount of sense when there appears to be some doubt over the archivability of digital files.
