I was recently hired to photograph this restaurant for an architecture firm. They wanted a dark and moody look however, the only time available to photography it was 12-5, in the middle of the day.
I used generative fill in Photoshop to change the view out of the window to look like night or an early blue hour. I was surprised at by how well it worked. It's not perfect but it's pretty darn good. Other than that, I lit the bar with several flash shots with my Godox Ad300 pro and blended them together with a brush on a low opacity and masking in photoshop. I then did some other basic adjustments in Lightroom along with some selective warming.
nice
