I want to see the process of taking real pictures together. It would be nice to see the first and second steps of the sequence, such as setting the angle and setting the aperture. And one question is, I want to open the aperture and do out-focusing, but when I adjust the speed with the lever, I can't help but close the aperture a little bit, and I wonder if there's any other way. I'm worried when I want to get out of focus and get the right exposure.
