Evening all. Anyone out there with their chemistry hat on care to surmise what is actually/possibly inside a bottle of Jessops Econodev? Bought a bottle yesterday to try out. Be nice if it was Rodinal; no, I'm not that lucky 😉

Take care everyone.

If I remember correctly, the econodev was used for development of exposed paper but I have not used this for film development. I have used Jessops Econotol with film with very good success in the past definitely with Ilford Delta 400.

Your dev should still work with film but this depends on the film that you have used along with the film speed.

In a nut shell the stuff you have is not Rodinal for good reason. Rodinal works really well with some films at high dilution but produces high sharpness at the expense of bigger grain but can produce some nasty size grain with othe film types. The jessops stuff is a good all rounder.

Hope this helps.

Hi Fred: the gumph on the bottle reads "Photochem Econodev Universal 2 for all monochrome film and paper" Sounds more like PQ universal as in Ilford only I don't recall the dilution being so high? Didn't think it was Rodinal, shame, thought I found another stealth R09 copy. Wiltshire......lucky man.

All the best

Many many years ago, the British photographic technical writer A.M. Carlsson reported that the then-available Ilford Ilfospeed (not the Multigrade version, later just known as Multigrade) print developed could work as a very fine grain film developer, when used under high dilutions: in the order of 1:60 to 1:100. I tried it and the results were most satisfactory; normal print developers simply do not behave that way, even PQU is not recommended as a general-purpose film developer. Perhaps Jessops found some way to make it work?

Hi Seele.....I really hope so! Find out latter tonight? If it don't you'll hear the scream, even down there.

Take care
