If you do a bit of research, you will find lots of finger pointing regarding all the fires we have in the Western United States. I will place my own hypothesis here… if you have oxygen, heat, and fuel you will have a fire. These images are from the L Road fire (State Rte. 24) and the Vantage fire (I-90).
The color images were shot on Velvia 50 with the Voigtlander R3M and 7artisans 50mm 1.1 lens and developed at The Darkroom. The black and white images were shot on the Voigtlander R4M and 25F4 Lens. The film was Kodak Tmax P3200 shot at 800 and developed in HC-110(1:31) for 8 minutes 30 seconds.
