History
I used to be a heavy user of Kodachrome - especially Kodachrome 25.
Before digital photography got started I recall reading an article suggesting that digital images would never compete with K25 as such 35mm slides had the equivalent of 50 million pixels. I don't know how that figure was determined, but full frame DSLRs are getting close to that figure.
As far as the colours go, modern software can simulate the Kodachrome look in digital images. It is possible to change the colour saturation simply by pulling a slider on a panel across a computer screen.
I also noticed that on my Nikon 9000 scanner, there is a special setting for scanning Kodachrome slides.
I began to move away from Kodachrome when the developers started to disappear. Last time I used it, it had to be sent to Toronto and took about a week (from Vancouver). So I started using Fujichrome E-6 Velvia slides instead.
I don't miss Kodachrome. It just became less practical to use and killed itself. Shooting RAW, I can take close to 2,000 images on a single card and being able to take only 36 images and then having to put in a new roll is just too inconvenient nowadays. The cost of Kodachrome complete with processing also is far more than using digital cards. The above 16-Gig card can hold the equivalent of over 50 rolls of Kodachrome. The film costs just no longer make any kind of sense.
As it is archival in nature, I guess my slides will be around for a long time, but so will my digital images.
How about Panatomic X film? ASA 25. Supposedly grainless (if developed properly). I wonder how many megapixels a 35mm frame of this film is equivalent to?
