    Lumen & Somni

    A dreamy semi-realistic look with focus on lighting.

    • Sampler: DPM++ 2M Karras / Euler a / DPM++ SDE Karras

    • Recommended CFG: 4-6, I usually use 5

    • Steps: 30-40, 35 is a good baseline

    Put these tags before the main prompt:

    masterpiece, best quality.
    Your prompt

    For more lifelike results add after your main prompt:

    Realistic, fine details, incredibly lifelike

    For example:

    masterpiece, best quality.
    1girl, red dress, long blonde hair, wavy hair, sunglasses, sitting on a bench in a park, crossed legs, upper body focus, light rays, morning, depth of field.
    Realistic, fine details, incredibly lifelike

    You can use period sign to break up your prompt, in my experience it produces marginally better results.

    Negative tags:

    worst quality, bad quality

    use deformed, bad anatomy, bad hands sparingly if you're getting bad results with anatomy and hands, especially if you're having trouble with multiple people in the scene.

    In general avoid using too many quality tags, it may affect your main prompt negatively.

    Glint

    Shiny, sparkly, detailed eyes, expressive lighting

    Atmos

    Semi-realistic atmospheric look with bold colors

    Glint and Atmos quality tags

    • Sampler: DPM++ 2M / Eulaer a / DPM++ SDE Karras / Experiment

    • CFG 4-7

    • Steps: 30-40

    • VAE baked in for all models

    1. Semi-realistic soft look

    Positive

    masterpiece, best quality, highres, high quality.

    Negative

    worst quality, bad_quality, 

    2. Higher detail and contrast

    masterpiece, best quality, absurdres, high quality, aesthetic, 8k,

    Negative

    worst quality, bad quality, poorly detailed, bad anatomy, bad hands, ugly, sloppy, sketch

    3. Lazy negative

    It's simple, tends to go towards cleaner anime look.

    Many thanks❤️ to @reijlita, @Jedas and @freckledvixon for supporting this little endeavour. This merge would not exist without their amazing models.


    This model was made with artistic expression in mind. It can produce NSFW content, but that has never been my focus. Each version is it's own thing, not just an upgrade.

    Isn't there already a different Chroma? Why muddy the waters by taking a pre-existing name?

    Aside from that -- The example images look great. How is this model for male focus content? SFW / NSFW?

    1. You're right, I did check for the same name but only between IL models. Still considering if I should change it.
    2. Base models I used had a strong female-bias, I assume it's far from perfect for male generation. I plan to test and add more SFW male examples at least, when I have some time this weekend.

    1) All good. I just remember Chroma because the stablediffusion subreddit loves Chroma and talks it up a ton haha.

    2) I'm a bit limited on my remaining storage currently, so until the model is a bit more friendly toward male-focus content I'll have to pass on downloading it.

    For the quality of your presentation and what I've seen from your example images, though, I've given the model a big ol' thumbs up.

    Looks really nice! If time allows for it I would definitely appreciate training more male focus data :)

    MysticFrostwind Thank you for the thumbs up, I realize there are fewer male-centric models, and will keep that in mind for the future. Also, almost all of images I generate/post are in PG-R range. (I think I have maybe a couple that are rated X) so I am often clueless what these merges are capable of.

    Yes, I recieved their permission, and replaced one model in the mix (author didn't reply to me). Thanks for pointing this out.

    Uh, yeah he can.

    if your model is derived from Illustrious v0.1, you cannot legally add a “no merging/no reupload” clause that curtails those rights. Any derivative must keep FAIPL-compatible terms and provide corresponding source/weights per the license.

    Just because someone makes a custom version of illustrious' original model that doesn't give them leave to restrict the actions of others.

    Civitai might have their own TOS and that can be enforced, sure, but if foton wanted to post their original merge to a place that allows it then there is nothing anyone can do about it.
