I didn't think it could be done.

    I exhausted my working LPD.

    First time in 4 years. Normally do something goofy to ruin it but I actually wore it out, I must be getting better at this.

    Norman I think this is Ethol LPD. Matt at Agphotographic sells it but is waiting for fresh stock. It is a powder in a tin with legendary keeping properties. Have a look at Ag's write up

    Others in the U.K. such as Silverprint might also stock it

    You were replenishing it per instructions? You can certainly exhaust a single bath by printing but it takes a lot of printing. I normally discard it from time and don't print enough to wear it out from use. I've kept a working strength bottle mixed in September and made prints in January that were _almost_ indistinguishable from prints made with fresh working strength mix, though it took it about .25 grades more contrast IIRC (required splitting exposure between filters for closest match.)

    Not per instructions. I may have to get more scientific going forward.

    I've been mixing a liter of 1:3 and just topping up the working solution with that. Normally I'd contaminate it or spill some or whatnot. This is the first time I've exhausted it.

    Mark, did it abruptly stop or slowly stop working? It sounds like you were surprised, when did you know? LPD is a terrific developer. Been printing 5x7's?

    Hi Curt,

    No not terribly abrupt, but it should be noted that my working solution volume is only 160ml for the JOBO. It's also not a complaint, I love LPD.

    I had switched to a different roll of film and was trying to nail the exposure and contrast and was starting to get prints that weren't matching what the enlarger meter was telling me but I was liking the warmth of the prints. It became clear about 3 runs later when the prints came out very underdeveloped and overly warm in color.

    Now that I've seen how this happens I can catch it with more aggressive replenishment next time.

    I had this happen to me with a three year old batch of replenished LPD. I had been sloppy with replenishing after not using it for a while. Otherwise, it never runs out of steam.
    Bromides and such do build up, and eventually it's a good idea to mix a new batch, where the new working solution is 1 part fresh stock, and 2 parts old developer. That seems to properly revitalize the activity of the developer.

    I have of couple cans on hand all the time. It's in a category by itself. I'm glad to see it continue to be used.

    I love LPD. I use it as my standard paper developer. The only other one I use is Ilford WT with their WT paper. For neutral tones it's LPD. I could try diluting it for warm tones and compare that to the Ilford developer, but I like the warm results with Ilford and I have to mix two batches either way.

    Speaking of that I need to reorder.
