Plus x asa?

Just received it. What asa should I shoot it at? 200?
Using hc110 dilution B, so 5mins

I always shot it at box speed where I could ... it has unique tones but I would imagine 200 would be ok, maybe more contrast I would think.

Plus-X was an ISO-125 film, at least during the time I have known of the film (30 yrs!). I would not shoot it at 200, that's a 2/3 stop underexposure, and your film looks old, so it'll have lost some speed from aging. I'd start at ISO-80.

 

[jusxusfanatic]

Oh wow, even lower! Alright the I'll just shoot it at 125. Thanks guys!

Plus-X was ASA 64 film until 1960 when the standard was reviewed. Overnight its speed doubled to 125.

Between 1939 when it was introduced and 2011 when it was discontinued Plus-X was reformulated by Kodak more than 5 times. This makes it hard to advise speed or developing conditions - the last reformulation modified the development times substantially but did nothing to the speed, for instance.

Never knew that, that's interesting

So still 5mins for developing?

 

[Freakscene]

I have no idea without knowing the vintage of your Plus-X. Do you know its expiry date?

Plus-X of any vintage will certainly *work* in HC-110 Dil. B but so will just about everything in HC-110. Start there if you need a working starting point. Rodinal and good old D-76 at 1:1 were also standards back in the day. I'd hunt some real Microdol-X at 1:0 at 64 if I had a few rolls

 

[jusxusfanatic]

I think 197x. Yea for now I can only use hc110

 

[znapper]

I develop my plus-x in HC110 B between 5 and 6 minutes, depending on the light.

I normally shoot mine at EI 100.

 

[jusxusfanatic]

Sounds good. Gonna shoot it at 100 as you guys told me to shoot it at a slower speed

 

[jusxusfanatic]

I'll develop it for roughly 4mins and 45secs

Around 5 minutes at 20 degrees C sounds right according to half-way down this page:

On a semi-related note, I bought some old Plus-X online to shoot with, but when I developed it, it had already been used. There were a bunch of pictures of kids playing baseball in what looked like the 1970s!

Rate it at box speed and use some med-low contrast developer to get most out of it. Microdol and D-23 work wonderfully with it.

With X-tol 1+3:

Resting and venting...

With home brew D-76:


Of old doors again...

With Microdol:


It's a door thing again...
