I'm not a big fan of HC-110, but I do admit that it does have advantages. Have you tried using it at higher dilutions? That would surely give you longer development times you want. I realize that documentation for higher dilutions may be a bit scarce, but you can get some reasonable starting times by extrapolating from what is available.

Have you tried a more dilute solution of LC29? More dilute
devs usually require a longer dev time...LC29 is great stuff,
I think I'd find a way to make it work or, accept (rejoice in)
the very short dev times.

More dilute? First to try although solution volume may be
a limiting factor. Another option would add a deactivator.
I'd consider adding some small amount of bicarbonate of
soda, baking powder. Trial and error. Dan

After switching to Jobo drums I diluted my my HC110 to 1:70 giving me development times between 10-12 minutes.

I think LC29 1+29 is the equivalent of HC110 dilution B. Maybe it is possible to experiment with increasing dilution.

Mark,

what film format are you using? Results will vary in graininess considering the size of the film towards enlargements.

Kind regards,
Geert

I'm using 35mm and 120 (occasionally 4x5). It is not grain that is the problem. It is the fact that I sometimes get short times for N development so contracting development for high contrast scenes sometimes becomes a bit precarious.

I started the thread by just speculating as to whether there was another economical long lasting developer that can be used in Jobos that has longer development tme than LC29. I can get along with LC29 for most things, but it would be nice to have an equivalent fine grain developer that would extend the times a bit.

Searches came up with two cheap alternatives: FD10 and Aculux; but most people seem to recommend DDX and no-one seems to have any experience of Aculux or FD10. I think DDX is expensive, but as Pentaxuser says it is not THAT expensive all things considered. So I am now thinking I may give it a try again (I have used it before and liked the results).

Cheers.

Just a follow up to this.

I was ordering some stuff online and the place sold Aculux 3. I thought what the heck and bought a bottle just to try. It is fine and I can get much longer times if I need to. It has 2 regular dilutions: 1+9 and 1+14. With 1+14 I get times over 10 minutes for HP5 in the Jobo. The negatives are great. I'm going to try 1+9 next. It's also very cheap.

Thanks for this. Is this book worth getting? I have not come across it before.

Sorry Mark I somehow missed this post although I have replied to a later post. You must have wondered why this odd behaviour on my part.

The book is very good on Jobo equipment and both C41, E6 and the RA4 print process and Cibachrome. It even covers the R3 process for reversal materials. The fact that it covers a process which to all intents and purposes is now defunct is also its drawback. Namely it was published in 1992 and some of the kits have been superceded and in that sense is becoming out of date. Essentially he covers Pan F, FP4+ and D400 only and 3 Ilford devs, ID11 Perceptol and Microphen but comments on others. You could work out times for others from his fairly comprehensive outline for what works and what doesn't.

As far as B&W is concerned, the same comment applies i.e. it covers only a small range of B&W films and developers but the instructions and conclusions still hold good, I'd say.

Overall I'd say it is worth looking for and buying. I'd try Amazon first. If you ever get the chance try Hay-on Wye. The bookshop capitol of the world! There must have been about 6 shops there at least all catering for photography with massive secondhand stocks.

Good as the book is, I was amazed to see it on e-bay recently and fetch £33! I think this was way over the odds but it may be very scarce now. E-bay occasionally amazes me in terms of prices.

I want to keep mine but if you need the highlights of the B&W section and especially the dev times let me know via pm.

Thanks, Pentaxuser. I'll keep an eye out for a used copy.
