The effect is sometimes subtle, sometimes stark. Trained on a bunch of high-grain photos with a reduced dynamic range (particularly with crushed blacks/shadows) and warm color cast, this model brings an aesthetic that may feel pointless to some, and quite charming or romantic to others. Consider myself in the second camp (why I took the time to train it) but no hard feelings if it's not your thing. There are plenty of other styles on this site for you.

In my setup, no special prompt needed. But you may want to reinforce the prompt with "grainy analog photo". Avoid negative prompts that counter 'noise'. I run with Z-Image Turbo and just keep the LoRA strength at 1.0

In CIVITAI Generations: Testing this model in CivitAI's generator, I find I need to bump the strength of the LoRA up over 1.0 to see its effect. 1.2-1.3 maybe.
