<h2 id="afterdark-for-z-image-turbo-and-flux.2-klein">AfterDark for Z-Image Turbo &amp; Flux.2 Klein</h2>This LoRA enhances your images with more punch, contrast, depth of field, and lighting. It's been trained on a mixture of photographic content with a focus on low-key, film noir, and fashion photography. It makes things pop without destroying image quality (in fact, it often enhances quality). Suggested Z-Image Turbo Settings Model strength: 0.3-0.8 Samplers/schedulers:<ul><li>seeds_3 / beta</li><li>ddim / kl_optimal (or beta)</li><li>dpm_2_ancestral / sgm_uniform (or ddim_uniform)</li></ul>Suggested Flux.2 Klein 9b Settings Model strength: 0.3-1.2 Samplers:<ul><li>res_multistep</li><li>sa_solver</li><li>seeds_3</li><li>er_sde</li><li>ddim</li><li>...and so many more</li></ul>Distilled Cfg Scale: 1-1.5 Steps: 8-10 Base Cfg scale: 2.5-4 Steps: 40-55This LoRA works with both Flux.2 Klein 9b base and distilled. I often use the distilled version because it generates images much faster and the quality is still really good.v2 LoRA Technical DetailsThe Z-Image Turbo LoRA ended up with a loss value around 0.336 (this compares to v1 at around 0.71).The Flux.2 Klein 9B LoRA ended up with a loss value of 0.5129 (5.129e-01). It was a "low and slow" train with a low learning rate (5.0e-05) over 6,000 steps. This was much longer than the Z-Image Turbo LoRA's training, but I think it was worthwhile. I might use a more powerful GPU next time (I used an A40 for this one). A lot of training time went into these models followed by a lot of testing. I decided to keep the same model listing on Civitai simply because they were both trained from the exact same dataset (same images and captions). The training for the Klein version in ai-toolkit started off the same as the Z-Image one. I soon learned that wasn't going to work for Flux.2 Klein 9b so I adjusted the settings.Version 2 is very stable for both base models. In fact I find that I don't often like the distilled version of Klein 9b without this LoRA. Images are generally too bright for my taste and while you could apply a LUT or do post processing work on the images, I simply prefer to use this LoRA because it does more than just lighting.

AfterDark

Experimental Z-Image Base LoKR. I wasn't successful with LoRA yet, but this LoKR seemed to work pretty well. I may create another version after more testing. Please help me test! Note this is a large file so I also hope to make another version that's smaller in the future.
