Darkroom: Lith printing study from Prague

Praha Nový Svět, Reference PrintPraha Nový SvětReference Print Lith printing takes the darkroom magic to the next level. It's based on overexposing the paper under the enlarger and then developing it in a special diluted high contrast developer. It's called infectious development. The initial phase, incubation period, where nothing seems to be happening, is several minutes long, depending on the temperature of the developer. The development time is not constant. Rather, one has to carefully watch as the shadows start to quickly build up. When the print reaches a so called "snatch point", the print needs to be quickly pulled from the developer and submerged is stop bath. The infectious development is so fast at that point that it's best to skip the dripping off and move to the stop quickly, otherwise, the photo may go too dark.

It takes practice to pull the print at the right time as the darkroom conditions are not the best for evaluating the tones. It's a darkroom to begin with faintly illuminated by red (or green) light. Often, the practitioners also add a little bit of "old brown" developer to the mix making it even harder to see through. However, when it's just right, it's very exciting. The technique introduces colors to a black and white process without toning, and yes, toning is further also possible.

Unfortunately, the technique only works well with a limited pool of photographic papers and that pool seems to be shrinking as manufacturers change their formulas and governments introduce further chemical regulations. Who knows how much time this technique has left. I should make sure to enjoy it more while it's possible.

A good starting point for exposure is 2 - 3 stops overexposed. But how does one know what the right exposure would be? There are several methods but I choose a 2-step process. I first make a standard black and white print in a standard developer. This reference print provides me with the base exposure. It also gives me another version of the print to enjoy, put side by side, compare.

And now for the study sequence, technical information is under each print. Admittedly, the digital representations are approximations. I photographed the prints with a digital camera and processed them to look as the printed originals. But of course, a reflective surface of the paper is not the same as a monitor. And my monitor will be very different from yours, brightness, contrast, and color balance. Either way, hopefully the below will show you how the look of a lith print can change making small tweaks to the process.
