When you approaching a traffic light, can you tell the difference between the light colors? Is it subjective or objective? Of course anyone can measure the color accuracy, it's just that some think color accuracy does not matter to some degree. And that is a matter of taste. So what film is the most accurate? Kodak claims that Ektachrome 64 Professional is the most colour accurate film they sell. Some other photographers might tell you that they get better colour accuracy using Professional Kodachrome 64. In general, if you go for a higher saturation film, you can always knock the saturation down a bit for printing. In that case, choosing Velvia, or E100VS, or similar, might allow more room to get what you feel best matches the colour in the final printed image. Here's my thing. I like walking around in nature, looking at little things like veins in leaves, insects, patterns of insect holes in bark. I've been extremely unimpressed with my photographs, but the photos shot with velvia seem to most accurately re-create *my experience* in nature. I'm trying to figure out if my attitude towards nature brightens what I perceive, or if actually regular film is dull, as one of the velvia-using nature photograhers told me. That could be the situation. I think the idea of lush green plants, and vibrant nature, could enhance the memory of these places. It is always easier to lower saturation, than to increase it. While imaging software can be used to boost colour saturation, it can often look much more "unnatural" than just using a highly saturated film. Ciao!

Digital also has some
unanswered conservation and archival questions that the real answers won't be known for say, 100 years (will someone still have a CD-ROM reader available? ex.: who has a 5.25" floppy drive anymore? 8" floppy?, etc...) The "Plugged In" column in the Baltimore Sun a couple of weeks ago reported that the National Archives is developing a universal digital storage format, from which data can be converted to whatever storage or playback technology happens to be in use at any time in the future. I'm not sure how or if this technology will be available to the general public or whether it will be affordable for the average person. But there will probably be companies that will convert data from one format to another for a fee, just as there are companies today that will tramsfer old home movies to video tape or DVD's. About 30 years ago I was involved in a NATO group on image processing, and we had the problem of exchanging data among labs with different storage media (7-track vs 9-track tape, different start and stop bits, end of file bits, etc.). Our solution was to develop a "transfer format" such that one lab could transform their data into the transfer format, and the receiving lab could transform the data into their format. It worked very well and became a NATO standard. So people are definitely working on the long-term data storage issues. And successes are in sight. Best regards from the top of the Chesapeake Bay-- |

So what film is the most accurate? It depends on accurate for what. The old Kodak might be more accurate for the mid grey, white, and skin tone, while Fiji might be more accurate for the intensed colors. Personally I feel the old Kodachrome has the best skin tone and the best balanced vividity and fidelity. Now people may debate it's either Kodachrome of Fuji's Astia for the most pleasing skin tone. But Velvia? lots of people would easily agree that, if color accuracy is the goal, this is the last film you should consider. |
