My usual visual tags are volumetric lighting, depth of field, cinematic, vibrant, shadows, detailed but these may force realistic images even if you are trying to do a different style.

Use source_photo and Realistic tags to help get realistic images.

Make sure to keep CFG around 7 and Sampling Steps around 30.

Always use score_9, score_8_up, score_7_up, score_6_up, score_5_up, score_4_up you can remove the 4,5 and 6 one and you likely wont have any issues.

score_9, score_8_up, score_7_up, score_6_up, score_5_up, score_4_up, just describe what you want, tag1, tag2

Recommended Negatives: artist name, signature, only add more if you want to avoid things appearing in your generation like styles or objects/people. You don't need to use tons of random negatives like deformed fingers I highly doubt they work.

Use source_anime, source_photo, source_3d, etc.. to force or avoid certain styles. You won't see the style change that much but it can help.

If you really want styles other than photorealism, you can try, but its not guaranteed. Try using words like style of "stylehere", while putting source_photo, realistic in the negative prompt as well as describing elements of that style. Certain visual positive prompts can also force a realistic style as well, so try experimenting.

    If you go through the gallery below and look at badassdragoon2's images, you may find some examples of different styles you can use. Set 1, Set 2, Set 3, Set 4, Set 5, Set 6, Set 7, Set 8, and Set 9.
