I built a series of ComfyUI custom nodes that apply a few tricks from a Flux sampling and post processing (the post processing nodes can be used with any image generation or editing model) perspective that pushes photo realism and camera behaviour a bit further, since AI renders can sometimes look too clean and just slapping on some film grain and playing with exposure settings blindly isn't necessarily the best way to do it. So far, I'm quite happy with the results I'm getting. I'll probably share some more as I continue to work on it and more likely that not at some point share the custom nodes for download.
