This model was trained on the style of Antonio Mora who was known for his merging of images to create a emotional response. Most of his work was done with head shots and that is represented in the LoRA.
This LoRA will combine images to create a new way of seeing things. If you use the prompt double exposure it will enhance the LoRA strength but you don't need to. Just add the keyword amora-style and your image prompts to generate the overlay effect.
It can be used with any SDXL checkpoint. You can use the keywords amora-style, double exposure style, and double exposure
I recommend DPM++2M Karras with 30 Steps
I look forward to seeing your images
