Every year in early October, the Great Stone Wall Pumpkin Festival is held on the grounds of a museum in southeastern Michigan. It actually supports charity and is much more benign than this image might suggest. Flames are restricted to the candles inside the carved pumpkins.
The Jack o' lanterns are from a photo taken last year. What you see is on the order of 5% of the original image.
ISO 100, 30 seconds, f/8, 17mm
The sky was taken almost exactly 10 years before at a different location.
ISO 200, 0.8 second, f/5.3, 230mm
Alien Skin Eye Candy for the flames (5 layers so the flames could be adjusted for each pumpkin -- needed to mask all layers so the others could still be seen)
Nik Color Efex 4 -- Reflector Efex / Glamour Glow / Dark Contrasts all as one layer
Then, the sky was added.
Uniform gradient vignette all the way around plus some additional darkening of the sky in the upper right corner
