slow ASA / ISO Film

[TimeShot]

Hello,

While researching film a thought came to me, “what is the slowest Color Negative and Positive films sold today”? I would like to try some slow film.

Velvia (pos) is ISO 50.
Ektar (neg) is ISO 100.

There are more, but these are the only ones I've shot. I mostly shoot B&W though.

Ah, slow-speed films, a very unfortunately dying breed.

Why, only 15 years ago you could get Kodachrome 25, Ektar 25, Kodachrome 64, Ektachrome 64 (D and T), and a fair few others.

Nowadays you are mainly down to the aforementioned selection: Fujichrome Velvia 50 and Kodak EKTAR 100 or Fujicolour Superia Reala.

Of course if you know a handy ECN-2 lab then Kodak VISION2 50D is a very very nice colour negative film 😉

It looks as if the slowest color negative is 100 asa/iso. Efke and Adox make 25 asa b&w film. Vision 2 sounds like fun, but couldn't find a Co. for processing. I'll leave that fun experiment to you. I have shot Eastman 5222 it produces quality negatives processed in D76. I've never shot Velvia 50, it receives great reviews, just for the fun I'll probably give that a try.
Thanks

What effect are you trying to achieve?

Although I also mourn the emulsions that are no longer available, I think you could you achieve the majority of the effect with an ND filter on a modern film and an ND filter. If you really "liked the look" of kodachrome 25 for example your screwed, but that doesn't sound like what your asking.

If you just want to shoot in full daylight at a wide aperture for low DOF, slow shutter speed for motion blur, or fill-flash in daylight for awesomeness with an old-school camera (1/1000 sec shutter speed, 1/60sec flash sync) you can do it with ASA100film and an ND filter very easily.

You nailed it! I'm playing around and experimenting. Photography is a hobby and just trying to make it challenging.

Hello,

Slowest color positive: Velvia 50

Slowest color negative: Kodak Gold 100, Ektar 100, Fujicolor 100 (offered only in some markets), Fuji Reala 100 (120).
And then Kodak and Fuji offer ISO 100 emulsions specially designed for some tropical / developing countries (emulsions which are more tolerant to heat and humidity).

Velvia 50 can be pulled 2/3 - 1 stop to ISO 25-32 with very good results. Any good professional lab will do it for you (or you do it by yourselve with home processing).

All ISO 100 color negativ films can be exposed @ ISO 50 without problems (grain will be finer, colors a bit more saturated, sharpness is a bit less, shadow detail will increase). No pulling needed, regular development.
Some films even @ ISO 25 show very good results (Reala for example, Fuji 160 NS and Portra 160).

If you need longer shutter times, you can use either a polarization filter, or neutral grey / ND filters.
