I recently did a live stream on the simple compositing method I used to create my Solar Eclipse image in Photoshop. In the video, I show my method of creating dark image composites using Photoshop CC and layer modes. It’s one of the easiest methods of compositing an image and doesn’t require complex masking (in most cases).
I forgot to share it here when I streamed it. I apologize for that and I hope you find it useful now!
