Several problems in photography

How's the weather? Under normal circumstances, only the clouds in the DC layer can produce the effect of blue sky and white clouds. There are too many stratospheric clouds, and it will be white on a sunny day. Even if it looks like blue sky and white clouds, the effect of blue sky and white clouds is not obvious if the polarized light in the sky is not filtered out. What you need at this time is a polarizer. When it makes an angle of 90 with the direction of sunlight, turn the polarizer until a satisfactory result appears, and other settings are useless.

2. Turn the camera to the M position, and focus manually until a blur appears. This method is suitable for any scene, including the "nobody cares" shooting scene, that is, the background without foreground or the foreground without background. You only need to defocus the scene that is almost in the same plane at any aperture setting.

3. Use a soft mask, or adjust the flash angle to produce diffused light, and adjust the sensitivity to ISO 100 or even lower. If it still doesn't work, simply give up the flash and increase the sensitivity. Many cameras have anti-noise function, and use good sensitivity to shoot.
