I've another Train Simulator Classic Gemini-enhanced screenshot to show off.
<link>
Here's the original, undoctored screenshot <link>
Here's what I told Gemini to do:
"Transform this Train Simulator Classic screenshot of a steam-locomotive-headed passenger train stopped at a station into a photorealistic image. Create images of the train driver and fireman in mid-1950s British Railways attire, seen standing on the platform just outside the locomotive cab door, as if in the process of friendly chatter. Create around 15 passengers, in 1950s British attire, on the station platform in the process of boarding the train. None of the 15ish passengers should be trying to board the black locomotive, just the passenger coaches."<link>
Here's what Gemini gave me <link>
Though it didn't follow my instruction to the letter, I'm as pleased as punch with the result. The one issue that I have is that Gemini, without my consent, changed the locomotive's destination-code disks into a single lantern above the smokebox door. A lantern in that position indeed designated a "stopping passenger service," which is what our train is. But a train of that era, on that particular railway, would use disk codes, as seen in the original screenshot.
