Kodak Is Bringing Back Ektachrome Film (petapixel.com)

sandbagger writes: Kodak, the film stock maker, is bringing back the Ektachrome film stock that was the popular alternative to its other product, Kodachrome. The Ektachrome is more sensitive to the cool side of the spectrum as opposed to the warmer Kodachrome. Apparently the product will be back on shelves later this year. âoeThe reintroduction of one of the most iconic films is supported by the growing popularity of analog photography and a resurgence in shooting film,â Kodak Alaris says. âoeResurgence in the popularity of analog photography has created demand for new and old film products alike. Sales of professional photographic films have been steadily rising over the last few years, with professionals and enthusiasts rediscovering the artistic control offered by manual processes and the creative satisfaction of a physical end product.â

      Kodak didn't miss the boat. They made the boat. They invented the digital camera in 1975. They were the pioneer of digital sensor technology. In the 1990s they made the first series of digital backs which fit into the film slot of existing professional SLRs (with a hard drive for storing the pictures). The damn things cost $20,000, but were immensely popular with the press who often had reporters shooting in remote locations where it was impractical to develop film. The reason Kodak has managed to stick around this long is because they owned the vast majority of early patents on digital photography. So they were kept afloat by a huge amount of royalties.

      They knew exactly where the future lay. How they screwed up is that they didn't have a marketable technology once film was gone. Fuji at least had the foresight to branch out into making cameras (decent cameras, not the cheap consumer crap Kodak churned out). So when Fuji's film revenue dried up, they had camera revenue to fall back on. Film cameras and digital cameras aren't all that different to make. Kodak OTOH only concentrated on the low-end consumer camera market (e.g. disposable cameras). Digital cameras made this camera market segment obsolete right along with film, leaving Kodak with no marketable consumer products. They were the leader in sensor technology, but didn't own any fabs. That meant they knew what to make, but they didn't know how to make it. So Sony, who had a lot of experience making electronics, ended up dominating the digital sensor market (most camera phones and point and shoot digicams use Sony sensors).

      I'm going to disagree just a little. Photos taken with Ektachrome Film tend to look like they came from 1960-1970, where as most photos taken after 1980 have a brighter, wider color gamut (at least when the negatives are scanned.) I scanned my familiy's complete negative collection spanning several versions of Kodak film and some films are "purple" some are "orange" when looked at straight on. But only a few strips out of all of them ever made the scanner panic and be unable to determine the correct color profile, those being ones taken around 1970.

      What I'm getting at however is that the reason people may wish to go back to regular film is that the one thing that film does that digital phones can not do is soft edges and soft-focus. Sure a overkill 60Mpixel photo is great, but you have so little control over how an image is focused digitally because the sensor doesn't snap the entire image at once, especially in CMOS sensors. So you get a kind of "roll" or "wobble" in images that should actually be still. In a film camera, this is real motion blur. In a digital camera it's just rolling shutter effect that looks hideous.

Right. Even Sony, by then, had a rep for making video cameras & they got themselves some more cred by using Zeiss-branded lenses. Panasonic, likewise, released Leica-branded digicams.

One spin-off was PhotoCD for which they had great plans - but in practice I think it just got used by semi-pros who wanted a cheap way of digitising their slides.

    . ...Unless it's 80 square inches and no camera... and no Light...
    We, (I had a little help...), actually developed the Tech. Not puny Photons, but Protons, and later right up to 209Bi Nuclei. Accelerate a Bunch of them, ("Bunching" has a particular and specific meaning here...), and expose a sheet of Kodak X-Ray Film for anywhere between several seconds and ~2 Nanoseconds, depending on Dosimetry, at the end of the Beamline, and then run the sheet through a unique, in the truest sense of the word, Kodak X-Ray Film Developer. Only one was ever made.
    Whether the Dosage was a few Nuclei a second, or a few Billion, we had it sussed out.
    But Why?
    To this day, there is no substitute for Film in this application. Nobody makes 8X10 inch Sensors, and if they did, those Sensors would soon be ruined.
    We would evaluate the Dosimetry under a Scanner, (A Scanner here means a device that a Scanner, a Person, uses.), for uniformity over a specified field, typically a six inch circle. Many Accelerator quirks can make uniformity, ununiform.
    For important Runs, we might go through a hundred exposures before The Experiment.

    It isn't enough that the chips in the Birds overhead are toughened against SEU; we could evaluate entire Boards, and how all those separate Chips interact when... attacked. Theoretically by Solar Storms.
    But by a curious Historical Accident, this wasn't any Star Wars scenario. It was started by John Lawrence, the brother of Ernest O. There are decades-long experiments ongoing in Evolutionary Biology. When DNA gets zapped, which happens all the time, how many Generations does it take to diverge into a producing a new Species? Current estimates are between a thousand and ten thousand Reproductive Cycles.

    In my waning years, I have kept a few mementos. I have kept a few exposures of Starbursts. This is when, under the Scanner, a Nuclear Reaction takes place in the Emulsion and is visible. These Nuclear processes continued until the Kodak Film Developer froze them.

  9. Tube amplifiers are PART of the instrument... by Ellis+D.+Tripp · · Score: 3, Informative

    Musicians using tube amps makes sense, as the particular distortion of a pair of overdriven 6L6s is a huge part of the characteristic rock/blues "sound". The amplifier and it's distortion characteristics are an inherent part of the sound the player is trying to create.

    For REPRODUCTION of recorded music, the ideal amplifier would be a "piece of wire with gain", adding or subtracting nothing from the original signal except to increase it in level to drive speakers or headphones. This is where the use of tube amplifiers (especially the ridiculous audiophool stuff using single ended triodes and no negative feedback) can only DETRACT from the signal as the musician intended it to be heard.

    Tube amps are cool in their own right, and many of them are physically beautiful pieces of "functional artwork", but they are not "magical" by any means. It just happens that the particular type of odd-order harmonic distortion created by tubes happens to sound OK to many people. But it IS distortion, and technically is unwanted in REPRODUCING recorded content.

  10. Re:Fujichrome and stock tip by Pax681 · · Score: 2

    Fuji's T-grain emulsion is superior to kodak.. as someone who has his City and Guilds(yeah.. that old) and who's first job was in photography... fuji t-grain FTW!

    But it's color was garish.

    one man's garish is another man's vivid.
    for work with long focal length and tele-convertors I'd take t-grain over kodak film any day of the week bud ;) Also if you used their 600 film and uprated it to 3200 , popped on a soft focus filter and processed it as 3200 you got pastel portraits the easy way.. they were quite popular in the 80's
