Try shooting in the range of 24-80MM, and the lens K beyond this focal length becomes more obvious. There is no specific light and scene in the data setting. It can only be said that if the background is clear, the aperture is around F5.6, usually F4. Outdoor ISO200-400 plus 1 exposure. Exposure to ISO400-800 and 1-2 files on cloudy days or indoors, full-scale metering under forward light and single-point metering under reverse light. I would rather have a smaller role and go back to the later stage than unreasonable photo composition. Take more photos for post-production and synthesis.
