HSToric FOCUS FLUX

A new variant/component addition to our HSToric Color LoRA/Model Series.

Trained on HD scans of early color photos (circa 1900s-1910s) by Sergey Prokudin-Gorsky, who traveled and photographed widely in those years whilst perfecting implementations of a pioneering 3-color-composite photography technique.

This LoRA is aimed at being useful for:

  • Invoking the visual character of vivid antique color photographs.
  • Improving the general quality of realistic/photo-emulating inference, esp. in FLUX.1-schnell and Schnell-based models.
  • Adding uncanny luminous & chromatic effects/dynamics to outputs.
  • Producing satisfactory outputs at low step-count/resource expenditure.
  • Extending realism options under an unrevokable commercial license.
  • Raising overall crispness & exposure levels, with potential parallel improvements to textural quality/detailing.

Those interested in fast, quality, & open-license realistic inference are advised to combine this LoRA with our Historic Color Soon® models, already fine-tuned (in some large part) on different sub-sections/selections/fidelity-refinements of the same Prokudin-Gorsky dataset.

Historic Color Soon® V.1 was fine-tuned by us from HumbleMikey's Pixelwave Schnell V.1 model which, in its turn, is a generalized base checkpoint trained from FLUX.1-schnell by Black Forest Labs, consolidating (in comparison w/vanilla-base-Schnell) further inference speed improvements (more reliable results at 2-3 steps), whilst raising the overall quality and consistency standards across most aesthetic categories and at every step.

Historic Color Soon® V.2 was created through merging into V.1 a handful of LoRAs trained by us over a (fairly narrow) range of available realistic checkpoint models that are specifically Schnell-derived, so as to stay within the fairly open Apache 2.0 licensing domain (which was among our reasons to do all this in the first place).

Historic Color Soon® V.1 is available here in both Safetensors (fp8) & Diffusers formats.
Historic Color Soon® V.2 is, likewise, found here in both formats.
Both Historic Color Soon® checkpoints enable reliable generation at low step-counts (2 steps or more), with 3-4-step inference at 768x768 often producing photorealistic outputs at a quality comparable to Flux Dev, in as quickly as 20-30 seconds (with nothing else running) even on low-VRAM-GPU budget-level machines (including all M-series Macbooks).

You may try out the V2 checkpoint at one of our LoRA gallery spaces, along with this LoRA (and many others)!

This LoRA was trained by A.C.T. Soon® via the dedicated Flux Training Notebook by Ostris.

We urge you to explore the works of Prokudin-Gorsky for yourself, at the wonderfully organized online archive at this link, featuring many hundreds of high quality downloadable scans of composite color photo prints from the photographer's original glass plate negatives, available at this site alongside relatively recent restorations of a substantial portion of the images. The original glass-plate negatives are currently held at and administrated by the Library of Congress in Washington, DC, USA.

Trigger words

Pre-phrase prompts with HST or 'HST style photo' or 'HST style autochrome photograph' or 'HST style analog film photo' (or variations thereon) to reinforce the fine-tuning influnce/LoRA impact on image inference.

Historical Note:

Prokudin-Gorsky's color photography technique would involve three photo-exposures, either simultaneous or sequential, using specialized color-spectrum filters (basically R.B.G.: red, blue, and green), rendering a subject/shot onto glass plates covered with light-emulsive mixture.
The photographer's focus on refining the developer and filter quality, in tandem with his incessant and wide-ranging experimentation, and his artful optimizations of glass plates (generally unwieldly, esp. for color, and by the 1910's already becoming outmoded for B&W on-location shoots, though elsewise extra reliable) ultimately led him to produce a color photography oeuvre of much greater fidelity and vividness than achieved by most of his contemporaries.

At the same time, the peculiarities of the photographer's method, coupled with his exceptionally hands-on execution thereof, would manifest in a range of idyosyncratic color, light, and motion artifacts common across the resulting prints.

Seldom marring the image as a whole, and less grave than the weaknesses of some cp-emerging autochrome techniques, the warm color hazes & flares framing many of Prokudin-Gorsky's prints constitute a kind of ephemeral signature.
Alongside some of the more subtle chromatic, textural, and (in some measure) figural characteristics of his work, these auras have reliably imprinted themselves into this and other LoRAs and Models within our gallery of fine-tunes for Flux and StableDiffusion3.5, fine-tuned exclusively on non-synthetic (human-made and pre-curated) open-access data from iconic, influential, and/or otherwise compelling historical sources.
