I'm a professional real estate photographer who recently switched from Photoshop. I'm a light processor, but will occasionally replace a sky, ad a fire to a fireplace or put an image onto a tv or movie screen. In Photoshop it involves taking a jpeg of said fill content and dragging it to it's location, sizing it and adding perspective tweaks to fill the space. Could someone describe how to do that in Affinity please? I've attached an example. I'd like to put the football game onto the theater screen.
Thank you!
