I had just shot 2 rolls of Portra 400, pushing it one-stop, and now it was time to shoot a roll of 400TX. It was getting darker, I was manual focusing, so I needed at least an aperture of 2.8 to have a chance of correctly focusing so I pushed the roll by 2 stops. I developed the film in HC-110(1:31) for 6 minutes @20C. I had the Nikon 50mm 1.8 Series E on the camera.
