The most common misconceptions of novice photographers: large aperture and flash

Posted by Adminluckinartist on

In the case of insufficient light or backlighting scenes, should we open a large lens aperture to shoot, or start a flash to compensate for the light, in order to achieve the desired effect? Professor Herman, a veteran photographer, came back here to explain what places are suitable for large aperture, what occasions are suitable for flash, and what subjects are suitable for large aperture plus flash, and understand all the correct concepts in one breath.

The so-called large aperture lens, Herman's definition is that the aperture can reach more than F4 (including) lens. And flash, of course, refers to external flash. These two are often recognized by novices as sharp tools to speed up the shutter speed of the camera and improve the success rate of photography, but is this really the case?

Large aperture lenses can easily take shallow depth-of-field photographs using their large aperture. Of course, in the same environment, a larger aperture can increase the shutter speed of the camera, and naturally reduce the hand vibration problems that may arise.

So what about the flash? First answer: Flash is not helpful to increase shutter speed, but it can provide the light source we carry with us. It's up to you to decide whether to fight or not. Herman couldn't understand why people on the Internet overwhelmingly denied the flash, saying that playing in restaurants would affect others and so on. To be honest, with flashes, how to use them? Photographers should have a certain understanding. You can decide not to interfere with others. If Herman knows martial arts, doesn't it mean that Herman uses martial arts to solve all problems?
