How to choose av file or tv file for SLR photography?
AV file: aperture priority. Generally speaking, the aperture is first suitable for shooting still life and people's stillness. Controlling the aperture size changes the depth of field (that is, the background blur).
Other gears:
M: Full manual mode means that the aperture size and shutter speed should be set manually, which is usually used by experienced photographers or people holding photometers.
P: The aperture and shutter are automatically measured by the camera, so manual setting is not required. They belong to the legendary fool mode and are more suitable for novices.

Take close-ups of things that are still small, such as flowers, birds and insects: use AV files, the aperture should be f5.6 or below, the focal length should be above 50, and try to shoot within 1m to blur the background. Iso100 if the light is good; If the light is not good, iso is better within 400.
Shooting people: basically, we use a relatively large aperture (within f5.6) and a focal length of more than 50 mm. The shooting distance depends on the whole body, chest circumference and head shot, so the background is blurred, and AV files are used. Good light, iso 100, poor light, within iso400.
Night shooting: put tripod and AV file, customize white balance or incandescent lamp, the aperture above f8 and small aperture can make the light show starlight effect, and use the pre-lifting function of reflector to reduce the machine vibration caused by the lifting of reflector after pressing the shutter; Cover the viewfinder with a square cover on the strap to prevent stray light from entering from behind and affecting the image quality; Within iso200, making the exposure time as long as possible can make some people who have no intention of walking disappear from the picture, leaving no trace and purifying the scene.
