Photo 1. Focus on Red and Blue. All four shots were taken in very low indirect indoor lighting with the XT2 and 56mm 1.2. I kept the aperture wide open at f1.2. I also kept the ISO relatively low at 500 and 200. Because of the slow shutter speed — 1/2 to 1 second — at this setting, I used a tripod. All four were converted from Raw. Cropped but no editing. Specs: ISO 200, f1.2, 1/0.
Photo 2. Focus on license plate. XT2: ISO 200, 1.2, 1/0.
Photo 3. Focus on Red. XT2: ISO 500, f1.2, 1/2.
Photo 4. Focus on Blue. XT2: ISO 500, f1.2, 1/2.
