Used to love shooting with Agfachrome. Can you imagine shooting at ISO 50 today?

I could happily go back to shooting at ISO 64 again.

It takes slow film to shoot wide open apertures with fast lenses . . . unless one is okay being confined to shooting in the shade or indoors by window light. ISO 80 to 125 used to be considered "medium speed" for films. [ Yes, I'm old enough to remember that--ha, ha ]

Used Kodachrome 10 for a while, then moved up to the speedy 25! In the 2000's I was enamoured of Velvia (50). The greens, the greens ...

So riddle me this: Today's digital sensors are very good at what used to be fast film speeds (ISO 400+), are they just not good enough to produce a low-noise image at sub 100 ISO?
Apologies for taking the Takumar Club OT...

As far as my understanding of it goes, if a sensor has a base ISO of 100 then that means that it gives the best signal-to-noise ratio at that signal level. Using a higher ISO means applying hardware amplification up to a point, then digital signal processing for even higher ISO settings, and of course both those methods will inevitably amplify the noise too. Every DSLR I've ever used has fallen off a cliff for noise when it goes beyond the limit of its hardware amplification, although this is much more obvious in raw files than in jpegs.

Using digital processing to let the user select an ISO setting lower than the sensor's base ISO won't result in lower noise, as the hardware signal-to-noise ratio is what it is, so there's not much point in including that as an option (other than as a marketing gimmick).

No doubt someone with a PhD in Complicated Electronics will come along now and tell me that I've got it all wrong.

There's definitely a part of me that wishes digital cameras had never been invented. I kind of miss those days when the job was done at the moment we pressed the shutter and exposed our slides. But sadly the cost of film and the frustrations of trying to get decent scans means that I'm almost entirely digital nowadays.

In those everybody shot film days, I always envied the people who could shoot slides and know they would turn out! I have shot some batches of slides that were good, but some others that were terrible, for reasons I was never very sure of. It turned me into a print film guy, and one who usually shot at a third stop below box speed, just to insure the negatives wouldn't be too thin.

I'm still shooting some film though. I like being able to test an old--they call them "legacy"--lens on one of my Pentax dslrs, to learn some of its character and limitations, before shooting it on a film body, where it can show it's intended field of view. The film shooting is more expensive, but it has its own pleasures. It also makes me slow down, especially if the film body has no meter or no working meter, and I have to use my little handheld light meter. If need be, I can do some post-processing with the scan files from the processor, so the digital experience can actually enhance what I can get out of the film shooting.

I'm slowly getting more and more into film. I'm planning more of my shots with it than I am digital. Something about the process is more exciting to me. My trusty Spotmatic and 8 element 50mm f1.4 go almost everywhere with me nowadays.

But then again I'm in the demographic that has been bringing film back, so maybe it's just a fad

Whatever it is, it's intriguing!
