Day-to-night conversions is something I learned from a British Gentleman, a Photographer, who owns his own YouTUbe channel for his business, Jamie Mathlin Photography. I give him credit for the first eight images on this page because they are his images and he owns the copyright on them. He graciously allows us to post them as long as he recieves credit where credit is due.
The process of converting images from day-to-night requires a lengthy workflow and lots of patience. The process involves using Lightroom and Photoshop's AI and Generative Fill tools to convert, replace, and enhance with the additional use of masking and other AI tools integrated into the two platforms.
Everything I've done to these images, I learned from Jamie's instructional videos on his channel. If you would like to follow his process, please visit his channel at: https://www.youtube.com/@jamiermathlin
