Some questions about night and indoor photography! ! !

The D80 is fully qualified to be equipped with an external flash. In this case, you can easily use the "reflective flash" to turn the lamp holder to the ceiling or wall, so that the tough light will be scattered into soft surface light. The CCD area of D80 is only a little more than half of the full width of 35 mm, and the depth of field is relatively large. Can tolerate short focal length and large aperture depth of field. For the time being, the settings for not using external lights can be as follows: ISO400-800 (no higher, the noise will rise sharply), the aperture should be as large as possible, one gear (aperture priority is automatic), the camera end should be stable, and the elbow should be clamped with double ribs (anti-shake lens is the best). It is best to change the fixed focus of a large aperture, such as 28mm2.8 and 24mm2.8, and try to borrow camera light. I often do this when I take wedding photos in hotels. Noise, depth of field and dynamic clarity are acceptable, but if I often work in such an environment, it is convenient and professional to buy an external light.
