Film Speeds. ASA 100, 200 & etc.

It's been many years since I owned a Film SLR.

But it seems to me that, in addition to the ASA 100, 200 & 400 films, that there was an ASA 24 film that produced wonderful prints.

Am I confused here? Or, was there an ASA24 film????

An old tired, forgetful mind would like to know.

Kodachrome was available in ASA 25, and there probably was a Kodacolor film with the same speed rating. The original Kodachrome was ASA 12, as I recall. Several films were available rated at ASA 50 and 64

The lowest speed film I could recall using in my dad's Olympus Trip (35mm p&s) was some B&W Kodak at ASA64. But I later learned that there was something capable of hitting the ASA 25 you talked of. I just didn't know what brands there were at that time and I don't recall if the Olympus could accept it.

Original Kodachrome was actually ASA 10. Can you imagine? That's 1/40 second at f/8 in bright sun!
Maybe Kodacolor was ASA 25 when it was introduced, but I have a Kodak Photoguide from 1959 that says ASA 32. They may have improved it, of course. It was replaced by Kodacolor-X (originally ASA 64, later 80) in the early 60's.
From the late 80's to the late 90's, Kodak made Ektar 25, which was a color print film with extremely fine grain. They also had Royal Gold 25 for a year or two (possibly the same film renamed). Maybe one of those is the one you remember.

Are you thinking of Ektar 25 from Kodak? It was released in the late 80's around the same time as Tmax 100, I think. The faster versions(400-800, 1600?, I can't remember exactly) were called Ektapress.

Kodak's Technical Pan film (ASA 25) was a wonderful film to use, but they stopped making it some years ago. I recently found some sitting at the back of a closet -- it's still sitting in my refrigerator, because I'm afraid to use my last roll!

Here are a couple of links, based on a quick search on "the google":

Kodachrome II was also available in ASA 25. I had brought a Kodak Pony 135 from a co-worker and it still had a roll (non-DX coded) of it inside.

I have a boxed roll of Kodachrome 25 that expired in 1990

It's pretty much useless now though It would have been fun to shoot.
Don't know that I've heard of a ASA 24 film though.

Is it possible you remembered the number 24 from film boxes made in Europe or made for European customers? In many European countries a logarithmic counting was used. Till end of the sixties most films showed only DIN (Deutsche-Industrie-Norm), later they had both values, and only end of the eighties/beginning of the nineties there were ASA values only printed on the boxes.

Before WWII, the units were "Grad Scheiner" (Scheiner Degrees), after WWII they became an industrial standard and were renamed in DIN, and the neighbouring countries followed suit.

ASA25 = DIN15
ASA50 = DIN18
ASA100 = DIN21
ASA200 = DIN24
ASA400 = DIN27

The picture is the case of a consumer grade Kodacolor VR200 from 1999. It still shows the 24.

Per "The New Leica Manual" hardcover by Morgan and Lester, 1951: Kodak Panatomic-X in 1951 was ASA 24. The highest speed films listed were ASA 100 (Kodak Super-XX),
Most of the available light photography examples were shot at 1/4 to 1/10 second hand-held. Technique was very important back then.

The German Company Adox has a Film that is ASA 20 and needs it's own developer for best results.
I have a roll in my fridge, but as I am a total beginner, I decided to wait using it till I have at least a little experience.
