How to deal with the ISO contradiction of aperture shutter?

But I don't know if LZ has practiced ~ ~ When shooting scenery outdoors, we usually choose sunny days ~ ~ At this time, the illumination of natural light is very high ~ ~

Basically, when the aperture is 16, the shutter of1125 can be guaranteed ~ ~ when ISO100 ~ ~

Generally, digital cameras will not blur the image when the shutter is 1/30 ~ ~

ISO generally does not recommend manual operation, unless special effects are needed ~ ~ Otherwise, 100 is very good ~ ~ The photo quality of many cameras is seriously reduced after ISO is improved ~ ~

But if you use automatic gear, the camera is likely to get a higher shutter at the expense of automatically improving ISO ~ ~

In addition, what LZ ignores is that the optical anti-shake function of digital camera can also reduce the influence of hand shake on photos to a certain extent ~ ~

If you really need to shoot with a slow shutter, you need a large depth of field ~ ~ and don't improve the ISO tripod ~ ~ This contradiction can't be solved by setting parameters ~ ~ This is determined by the camera structure ~ ~

But many old photographers have mastered a pair of iron hands ~ ~ when holding a camera, they are as steady as Mount Tai ~ ~ For example, our photography teacher can take clear photos in a dark museum ~ ~ Very powerful ~ ~ And the battlefield cameraman you mentioned must have this ability ~ ~
