He uses the Hasselblad X1D, specifically on a shoot from the 2017 Nebraska State Llama and Alpaca Show. He likes using this because you work at a slower pace. He also does a lot of street photography, and has said with the work he didn't want to use flash to spook or disturb the animals.
Ruben Terlou
He uses a Phase One IQ3 100MP back. He got into documentary photography because he can tell important stories in different ways, and slows him down. He used the Phase One as he wanted sharpness, the best colour and best contrast.
Dan Westergren
He used the Fujifilm GFX 50S. He used 32-64mm f4 lens and a 110mm f2 for portraits in this series. He says he worked a lot more consciously when shooting with a digital medium format camera. He doesn't like perfection, he likes when things accidentally happen in photographs.
