style of the photographer Haris Nukem
Go follow him !
You can use ADdetailer for upgrade your image !
Train with something like 190 photography
Try to prompt like this: "harisnukemXL, photography of [your subject], [subjet description], [background], [style description like type of photo etc], <lora:Haris_Nukem_Style_XL:1>"
All images on exemple using DPM++ 2M Karras, 35 sampling steps, 6 GFC scale, 1024x1365.
No negatif, no ADdetail, just Juggernaut XL and the lora.
Have fun with it !
