Thank you Omar. This is an excellent article, but it stops just short of what I am hoping for. It says "Click 'show more' to display all of the available sltyles you can apply to your photo." What I really want to do is find a way to utilize my own reference images for styles rather than be limited by the ones provided in the filter, as nice as they are. Perhaps that is something that may be part of future releases. Unless it is an option now and I just can't seem to locate it.
I would like to know the ending of this story, too! While everyone loves and utilizes the preset images, I have utilized another program in the past where I could AI blend with my own images to create something unique that no one else has. So, looking for the answer: Can you upload your own image for style reference to utilize in "Style Transfer" with Photoshop CC 2021?
