This was so much fun.
I found this example on the web, I’m not creative enough to come up with so much detail… A towering medieval castle perched on the edge of a cliff, surrounded by swirling mist and illuminated by the full moon. A dragon flies overhead while knights on horseback ride through the castle gates below, ultra-detailed, high fantasy, cinematic lighting

Pretty cool, but in the example shown, the windows had light coming out of them
So I merely added… lights illuminating out of the windows. And…

Wow!
But the results sometime were nowhere near what I expected. For example…
I prompted: create an image of a IBM 1401 mainframe

I tried again and got

I then tried: Realistic IBM 1401 mainframe

Not so great! Looks nothing like a IBM 1401. But I just started playing with this.
I also tried a much more recognized and iconic mainframe, the IBM 360…generate a realistic image of a IBM 360 console

On the other hand… generate a image of mickey mouse

Don’t like him standing on the right. So I added… in the center

Impressive… to little ol’ me!
