Aperture priority shooting technology

Aperture priority automatic exposure (ISO automatic exposure) As long as the aperture value is set, the camera will automatically set the appropriate combination of shutter speed and ISO sensitivity, so it is not difficult to use this mode. Then let me introduce you to the technique of aperture priority shooting. Let's go and find out!

Aperture Priority Shooting Technology-Moderately Exposing Backlight Portrait

At the seaside, due to the noisy environment and strong light, we think the better time to shoot portraits is in the early morning or evening. At this time, the light is soft, and the warm sunshine will render the whole work into gorgeous warm orange. Backlight shooting can also solve the problem that models can't open their eyes and dare not look directly at the camera. We let the model stand in front of the light, and then the photographer moved to find the right shooting position. In order not to be overexposed to the sun, we can let the model's head block part of the sun, and the sunlight behind can give the model a charming "silhouette light". We choose "spot metering" mode to measure the model's face, and appropriately increase the exposure from 1/3 to 1, so that we can shoot a successful high-profile backlit portrait.

Using the "aperture priority" mode, the shutter speed can be automatically adjusted according to the aperture size, and the sensitivity can be improved if the shutter is too slow.

Aperture priority shooting skills-make your beach clean later

Aperture Priority Shooting Technology-Pre-processing

There may be many factors that affect the picture on the beach. It doesn't matter, we can easily make your beach clean by using the "imitation stamp" tool in PS. We can see that there are too many interference elements on the background beach in the original picture, which need to be adjusted.

Post-processing technology of aperture priority shooting

Pay attention to the flow and hardness of the brush when using "imitation printing". If it is too hard, the picture may become unreal. The irregular distribution of sand on the beach can actually cover up the use of our stamps.

Extended content: shooting skills of large aperture fixed focus lens

What is a large aperture fixed focus lens?

A large aperture lens is a lens with a maximum aperture of f/2.8, f/ 1.8, f/ 1.4 or even f/ 1.2; Fixed focus lens refers to a lens that can't zoom and has only one focal length. Large aperture fixed-focus lenses are also produced by Canon, Nikon, Sony and other factories such as Sigma and Tokyo. Commonly used focal lengths are 22mm, 35mm, 50mm, etc. It is recommended to buy 35mm APS-C camera and 50mm full-frame camera, and the shooting angle is closest to what human eyes can see.

What are the characteristics of large aperture fixed focus lens?

Large aperture (such as f/ 1.4, f/2.8, etc.). ) Let you absorb more light in the dark. Even if you hold it, you don't need to improve ISO to keep the shutter speed, so the photo quality is better and there is more room to play.

Fixed focus means that you cannot zoom in/out. If you want to shoot a wide angle or telephoto, you have to move by your body! However, due to the simple structure of fixed-focus lens, the imaging quality is often better than that of zoom lens.

Cheap, although it is a large aperture lens, the manufacturing process of fixed-focus lens is relatively simple, so the price is not high. For example, a Nikon 50mm f/ 1.8 G only costs 1000 Hong Kong dollars, and it is small and light.

Application example of large aperture fixed focus lens;

(a) Shooting fascinating shallow depth of field

How to use a large aperture lens without taking pictures of the depth of the scene? In addition to being generally used for portrait shooting, you can also use shallow depth of field effect for landscape shooting-adjust the aperture to f/ 1.8 and f/ 1.4, and you will find that the background of the subject becomes blurred, making the subject of the photo more prominent!

(2) Portable party/travel/activity mirror

When going to a party or traveling, it is very important to shoot easily. In many cases, you can only bring one camera and one mirror, so a large aperture fixed-focus lens with small size, light weight and deep scenery is the best choice without pushing ISO in low light! Although it is fixed focus, it is often not a wide-angle lens (50mm for APS-C format cameras should be multiplied by 1.5x! ), which makes it difficult to take a selfie manually, but I think it is very suitable to have a large aperture fixed-focus lens under the premise of "thin and good imaging".

(3) Hand-held shooting in low light

In some low-light environments, such as museums and night shooting, it may not be possible to shoot with a tripod. At this time, if the aperture is not large enough, it is often necessary to upgrade ISO to keep the safety shutter, but high ISO means high noise and degraded imaging quality. Therefore, using large apertures such as f/ 1.2 and f/ 1.4 can absorb more light and help to keep the ISO low. However, it should be noted that a large aperture will make the depth of field shallow and easy to lose focus. When shooting, keep the distance between the camera and the subject unchanged and don't move back and forth.

Postscript:

The 50mm f/ 1.8 large aperture fixed-focus lens has always been an important member of the "three treasures of the poor" because of its low price and good quality. If you are a player who has just bought a DSLR and is worried about what lens to buy, consider starting with a "large aperture fixed focus lens"!
