Thanks for all replies. Matt; I had thought that as the original jpg was only 600k it would upload. Resizing worked so I'll remember that in future. Koraks: as ever comprehensive. I looked at the Ian Leake site but that kit costs more than my entire (self-built) set-up. As for building my...

More info: I did look at enlarger timers but these were either analogue (wary of S.H. analogue timers), needed special plugs and/or wiring, limited to 99secs or far too expensive - or a combination of those . All I really want is something simple like the timers I've been using (attempt at...

OK try pic again

Not sure if this is the right place to post this but nothing more obvious so..... I bought this timer (pic attached) with a view to controlling my UK mains powered UV light box, but it arrived without any instructions. Can anyone provide really, really simple step-by-step instructions on: a)...

Does anyone have information about this holder for the Coolscan 8000 / 9000? I have one that has the anti-Newton glass in the 'lid' but missing from the main body. Was the glass missing also anti-Newton or plain glass? And any idea of thickness? Any information very appreciated. Barry

Thanks again to both. Drew Wiley wrote "Red, green, and blue are primaries. Cyan, magenta, and yellow are their respective complements." That explains a lot - no art background explains the rest. I've printed out the sites referred to - I'm still happier sitting reading paper, and I can add...

Koraks, Thanks for your usual comprehensive reply. I do appreciate that printing is based on subtractive colour and light is additive colour and that the filters RGB produced negatives which were printed in complementary colours and therefore the red filter is printed to green, the green to red...

In my dilettante way I've been looking into gum printing in 3 or 4 colours. I've produced CMYK seps using digital means but it occurred to me that the original gummists were more likely to have used RGB filters in camera to produce their negatives as I guess colour photography and electronic...

The reason for wanting a new thread was that after all this time I doubt anyone will see the post and if I was to write a description of my attempts I suspect not many will bother to scroll down to the end of such a log-dead thread

Almost 8 years ago a contributor calling themselves Nomad posted a series on this subject and briefly got a number of replies. Since then there doesn't appear to have been any follow-up. I've recently started to experiment with this process myself and searched all the obvious keywords with no...

Can you given an example? Err - no. not offhand! Probably misremembered that. Yes, I do realise that sulphite and (meta)bisulphite are different. Thanks for that comprehensive answer - I really wanted to confirm I could substitute metabisulphite for bisulphite - just found it a bit confusing.

About to demonstrate my lack of chemical knowledge here but.... According to Wikipedia "Sodium bisulfite is not a real compound,[2] but a mixture of salts that dissolve in water to give solutions composed of sodium and bisulfite ions." and: "Sodium metabisulfite.........an inorganic compound of...

Thanks for the replies chaps. I'll try bleach first and then carbonate - leaving the lye till last. Thanks again

I have a number of old glass plates (half-plate size) with old emulsion (used and developed) that have been failures at the time. I'd like to re-use them for re-coating but what's the best way of stripping off the old emulsion? Hot water alone isn't always successful - presumably because of...

Thanks for that Lachlan - very helpful. The 507 is indeed running 24v lamps so couldn't use that Transtab in any way but I will try the timer. Tried that - no light, so went back to basics; took all the lamps out and replaced them with new ones and 2 of the 4 came on! So it looks like I might...
