Steam hovertrain departing from the station
This an experiment, where I did the same promt + same seed BUT each run tried different variables.
Each run been doing just 400 iterations, around 10 minutes. Not super-detailed, not blurry mess, possible to see the difference.
Lets begin from the initial image.
At this point I had all the parameters set to default.
And then, changes began to happen.
MSE Epoches: 5 -> 30
MSE Epoches: 30 -> 128
MSE Epoches: 48
At this point felt like this parameter should not be adjusted anymore.
Next thing to adjust - Cutout Value. Default value is 64, but I was running with 48 all these samples.
Cutout: 48 -> 10
Cutout: 10 -> 90
I like this result the most. The top left corner seems the only thing I'd fix in photoshop, but the rest looks almost like a complete image. People are gathering at the station where the levitating train is about to depart, they walk at the sandy road along the fences in fields; at the left it is possible even to recognize the sheep, at the background right area - some kind of buildings or city structures. You could even see the outfit of people who walk on the train: rich people in dark blue suits with etches of orange, some rich madame in fluff red dress and large hat. Amazing one.
Cutout: 90 -> 150
Image became very readable, yet it began to feel like ugly photo-bash without having solid structure.
Cutout: 76
MSE Epoches: 25
Time to play with image modifiers.
Flip Horizontal: 0.4 -> 0.1
Padding: 0.8 -> 0.5;
Affine random degrees: 30 -> 45;
Affine translate: 0.1 -> 0.4
Flip horizontal: 0.1 -> 0.95
Affine random degrees: 45 -> 75
Affine translate: 0.1 -> 0.55
Okay, it already looks the best for now. Consistent structure and composition, proper foreground and background, clear and readable details, I could even tell there's a horse-drawn carriage at the left area. Buildings doesn't look like a mess anymore, no flying islands of image in the sky. Yet, this steampunk shoe doesn't look like a train haha!
Affine random perspective: 0.2 -> 0.5
