Kodak film speed

[greg_nixon2]

<p>I'm messing about with a Kodak Tourist II. I would like to run some FomaPan 100 through. Just for information's sake, what would the film speeds have been? On the back there is a selection of film types to set the reminder dial to. They are:<br>

plus X<br>

super XX<br>

Infra Red<br>

Daylight Type A<br>

Kodachrome<br>

Kodacolor<br>

Ektachrome<br>

Verichrome<br>

They may/would have changed, but its film speed cc 1952 that I'm after.<br>

Cheers<br>

<p> Just a few years ago! My recollection of the ones I am familiar with -- none of my reference books go back quite that far. All -- ASA.<br>

Others jump in if / as my memory is most likely fallible.<br>

Plus x was 125<br>

You didn't ask, but I think Panatomic X was 50<br>

Kodachrome was 25 then later 64 as KodachromeII<br>

Ektachrome was 64 then later 160<br>

Kodacolor was 80 (not at all sure since I didn't use that film)<br>

Verichrome Pan either 100 or 125?</p>

<p>Depends on year to some extent since changes were made and different systems employed.<br /> see Wikipedia for history (<a href="https://en.wikipedia.org/wiki/Film_speed">link</a>.)<br /> As noted there, Kodak ASA no.s were altered to eliminate a safety factor in 1960. The Tourist II, I think, was sometime in 1951.</p>

<p>Super XX was IIRC ASA 200, so this setting would be fine for ISO 100 after allowance for the safety factor which JDM mentions.</p>

<p>As well as I know, the early Kodachrome was about ASA 6, but that is older than I am.</p>

<p>Kodachrome II at the end was 25, and Kodachrome-X 64. </p>

<p>Ektachrome X was 64, and High Speed Ektachrome 160. </p>

<p>Kodacolor X was 80 when I knew it. </p>

<p>Mostly, I knew those in the 1960's and 1970's.</p>

Here - http://en.wikipedia.org/wiki/List_of_discontinued_photographic_films - is a Wikipedia listing of old

Kodak films.

<p>While the Wikipedia link does have some useful info, a few omissions, mainly older. Plus-X in the early to mid 1940's was ASA 50. Later in the decade it was improved and speed went to 80. These values could effectively be doubled because of the generous safety factor. Super XX in that day was Kodak's speed champ at ASA 100. Panatomic-X clocked in at ASA 25. Daylight Kodachrome was ASA 10 but became 25 when Kodachrome II replaced it. Verichrome was ASA 50 at the time. By the time Kodacolor became available in all sizes I believe it was ASA 32. Possibly in the early 60's might be when it was ASA 80. At least by the time the Kodapak cartridge was available.<br>

Kodak does have a time line somewhere but I don't think it lists ASA/ISO numbers. </p>

<p>you have a similar problem to the person wanting 620<br>

spools.<br>

I will give similar advice.<br>

see if a 120 spool will fit in the supply side<br>

develop it yourself.<br>

and look on the massive developing chart to find a way to develop<br>

to reduce speed.<br>

I think they Kodachome was not available at least for a long time<br>

in roll film sizes.<br>

if you have a tourist with an adjustable lens ans sgutter<br>

life will be eassier.</p>

<p>Most of the films have enough latitude to take the overexposure with current films, except in the brightest conditions. </p>

<p>I prefer cameras with a few choices for shutter speed or aperture, there are some with only I (instantaneous) and B (bulb). With older films, and all but the best lighting, you were supposed to use B, setting the camera on something solid, and somewhere between 1/10 and 1/2 second. </p>

<p>(The manuals are online for many of the old cameras.) </p>

<p>With today's films, we can do much better. </p>

<p>Most often, I use VP with my older cameras, but for ones using 120 film, I have used TMX or TMY, usually developed in HC-110 (B), though sometimes Diafine. </p>

<p>Excessive overexposure is still rarely a problem, underexposure more often.</p>
