Playing with AI to Create a Backdrop (first tries)

My back still isn't, um, "back" to 100% so I can't get to the layout. But I can play around with Google Gemini (an AI program) to try and create some more backdrop images to fill in behind the foreground buildings at the north end of Middletown . . .

I started by asking Gemini for "fronts of factory and mill buildings, viewed straight on" and got this image that included 4 images.



I then used the MS snipping tool to crop & save each of these images as a separate image. The one at the top left ("Riverfront Textiles") is fine to use as-is, but the others need to be rotated. So, I started with the image in the lower right ("Pinewood Paper"). Here are the screenshots of exactly what I did . . .



Not fantastic (when I rotated it, I lost a bit of the character of the varied roofline), but pretty darn good for less than 5 minutes' work.


I'll do the same thing with the other images and then see how they look. But HOLY COW! For someone like me that enjoys creating photo backdrops, Google Gemini is an amazing tool!

Just check out this before-and-after . . .

Here's the image I started with:

Point A

And here's what I ended up with:

Point B

Still a bit too "peak autumn" looking for my layout (which is set more in early Autumn), so I'll be doing some PhotoShop work to get it into final form, but from the B&W image to the image above took me no more than 7-10 minutes, if that.

Truly amazing!

I can't even imagine how long it would have taken me to get this result by regular PhotoShopping - even if I had all the skills needed. And this is certainly a long way from "just" colorizing a B&W photo (which I've been doing for over 5 years now - here's my original post on that, and the RMC article).

I actually screenshotted the nine separate instructions I used to get from Point A to Point B. So if anyone's interested in seeing those, let me know in the comments or contact me directly. It really is shockingly easy.

I'm not a huge fan of AI in most other contexts, but for making backdrops for your model railroad? I'm finding it pretty hard to beat. It's definitely a remarkable time to be in the hobby.

So give it a try - and if you do, I hope you'll let us know!
