Hi Francisco
Thanks for the kind words. Chicago is a great place to shoot, there is so much diversity in the architature here.
The fisheye effect is achived by using a fisheye lens and a custom mount for the RED ONE, and a standard f-mount for the Nikon. I create content for planetariums and digital domes, thus the fisheye look. Trust me, once you see a fulldome show, no other type of film will ever be able to give you the immersive feeling of the dome.
For SecondCity, the exposure time varried depending on the shot, but around 1-2 seconds per frame.
