I tried to create a High Key Lora, but it morphed a bit. It should add a High Key Element to your images. A style of lighting that is bright and even with lower contrast.
On lower LoRA weight it will behave as you would expect. Increase it and it will transfer your images in an unexpected but fascinating way.
I've included sample pictures that show examples with the different LoRA weight applied.
Go and experiment and share you images!
