Ilford Mark V Development

[Mani_Reshad]

Hey everyone!
I was looking forward to shooting some Ilford Mark V and to my knowledge it was tested and it is supposed to be shooted at ASA 100. I know that there’s remjet that needs to be removed prior to development but I was wondering what are the development times; I was also wondering if the development stages were the same as normal B&W films since I saw someone stating that it has a bleaching stage(as it is with ECN-2). I’m going to develop it in PCTEA and so I‘m looking for the D-76 1+1 development times(or honestly any other dilution as a starting point).
Thanks for the replies in advance.

Moved to the B&W film sub-forum.
I'm guessing you are referring to this film: https://filmphotographystore.com/pr...-mark-v-expired-1-roll?variant=44795562885294
Take a look at the Blog listed in that link - found here: https://photo-analogue.blogspot.com/2013/04/ilford-mk-v-motion-picture-film.html
I'd be surprised if it has remjet.

I had not heard of it until I read your post. I found out that it's a very old Ilford cine film but no mention was made of it being remjet It appears to have been the equivalent of HP5 in terms of speed but from what I found it needs to be exposed at 80 or 50 If you do an internet search you will find that reference to it and shots produced see to be mainly 50 speed

I only found times for Rodinal at about 8 mins and ID 11 stock at 11 mins If you have not yet exposed it then if it were me I'd cut it into at least three sections after exposure and process the first section in D76 stock at 11 mins then examine it and from that decide whether to increase or decrease the development time

Be prepared to get results that are reflect the age of the film

Best of luck

I know that there’s remjet that needs to be removed prior to development

Is there? That's unusual for a B&W film. I don't see any mention of it on the pages that discuss Ilford Mark V film. I'm sure people would have noticed it.

I saw someone stating that it has a bleaching stage

Can you provide a reference, please? If this is to be developed as a B&W negative, there will not be any bleaching required. A reversal bleach will be necessary if the goal is to create B&W transparencies. Maybe that's what the person meant.

I always figure that 35mm Movie film is generaly developed as a negative, only some 16mm and smaller B&W film is done as reeversal, and that term will apper on the Label in that case.

Mark V is quite old by now, so who knows what speed is a good starting point. I am not sure where I put my old Ilford data sheets.

My 1979 Compact Photo Lab gives a description of this film but no processing information. Rated 250 in daylight, negative pan motion picture film coated on 0.005 inch gray anti-halation base. So water rinse before development. "Speed can be doubled and users report good results with speeds as high as ASA 1300 using Microphen". I'd try D76 1+1 at 14 minutes as a starting point.

why a water rinse, Unless that is your normal procedure for films like HP5+ which is also on a grey base?

Indeed, there's no point to this. There's no way the antihalation measures will 'wash out' of a 35mm film base.

So water rinse before development.

Keep in mind that the anti-halation dye that washes out of esp. 120 roll film and sheet film (Fomapan is a prominent example) is totally harmless to processing solutions. No pre-rinse is needed on this account (it can be a good idea to fix development evenness problems, which is an unrelated issue).

A pre-wash does no harm and ensures that any bubbles from the developer are not attached to the film. And keeps your developer, stop bath, and fixer from turning green. Feel free to skip it.

I have always avoided the pre rinse as it is likly to dilute the developer in My furry little mind.

BTW, I did dig out my copy of the Photo lab index and at the time Ilford Had 3 35mm movie negatives listed. at 50, 80 and 250 ASA. All Just said to develop to a Gamma of 0.65 to 0.70

It would be very interesting to find a definitive source of information about Ilford cine film. Recently a large stash of 'Type 517' (aka FP4) was discovered and as speculation suggests it does not have a Remjet coating. An enterprising company is selling this as rolls of FP4 very cheaply and it's excellent stuff. Being FP4 and not FP4+ about two minutes extra in your normal developer is all that's needed.

you may be able to find the old Blue Ilford Tecnical information Binder which had a sheet on each of the films.


the few example I have used over the years were "normal film" no makers B&W movie film did use an remjet coatings as far as I can determine. the standard B&W process sequence for B&W does not have a Rem-Jet removal step.

The Ilford movie film before KeyKode has Ilford Safety Film every 18 inches but exposed to read corectly from the emulsion side. it has a number every foot for editing purposes and the letter at the start of that number depends on what film type you have.

Ilford DID set up to produce KeyKode edge printing, But I am not sure how long that was before they decided that seling Movie film was basicaly going to canabalise their still film market.

I THINK I recall Simon Galley as saying the movie film was indentical to the still film except for the Finishing. (but that may be a confused Memory)

I did manage to dig out the Mark V data sheet from Ilford!

(sheet a50.7 Dated L68)

Meter setting is given as 250 Daylight and 200 Tungsten, BUT minimum exposure is 500ASA Daylight and 400 Tungsten, :but only where Processing Conditions are Strictly related to exposure conditions.

Further speeds of up to 1300 asa have been realized with Microphen Fine Grain developer.

The recommended Control Gamma is 0.6 to 0.7 and the recommended Gradient is control is 0.55 to 0.65 Some curves of Gamma are given using ID-11 Developer.


the footage numbers every foot start with the Letter "S" or "T" for mark V

No developing times or Temperatures are referenced.other than the curves are based on a development temperature of 20C

of course 57 years later.....

There's a site called Labeauratoire (here: https://www.labeauratoire.com/film/IlfordMarkV/IMV.html) has a dev time for it in Caffenol for 17 min at 20ºc
