Principles of portrait photography

Principles of Portrait Photography. Friends who are interested in photography know that in traditional photography, there are many techniques for photographing portraits, but the best is to focus on the eyes. If the eyes are not in focus, then the photo will be out.

The photos are very soft and the portraits are lifeless, so let’s talk about the principles of portrait photography.

Principle of Portrait Photography 1 The principle of portrait photography is to focus on the eyes. It is very important to accurately focus on the eyes when shooting portraits.

If the eyes are not in focus, the entire photo will be soft and lose the key point.

No matter what pose the subject poses, no matter what angle the shot is taken from, the eyes must be accurately focused.

Especially when shooting at a wide aperture, the depth of field becomes smaller, and a slight shift in the focus position will cause the eyes to be out of focus. Photographers should pay attention to this.

The eyes are in focus. The eyes are not in focus. Magnified images of the eyes. Magnified images of the eyes. Take portraits from any angle and in any posture. Basically, the eyes are in focus. When shooting with a small digital camera, generally as long as you can focus on a certain part of the face.

If the position is in focus, you don’t have to worry too much about the focus position.

However, when using a high-pixel digital SLR camera, because the resolution of the image is very high, the out-of-focus phenomenon will be particularly obvious when zooming in.

In addition, because the image sensor of a digital SLR camera is large, it is prone to blurring.

When shooting with a 35mm full-frame camera, the blur is larger, so the focus requirements are more stringent, and you even have to pay attention to which part of the eye should be in focus.

Prevent shake, which is a taboo in portrait photography. Accurate focus. Details are also captured very sharply.

The eye is precisely focused, and you can even count the number of eyelashes when the image is enlarged and displayed. It is a photo that is pleasing to the eye.

Out of focus: The photo lacks sharpness. It should have been in focus on the eyes, but the focus point has shifted.

It is possible that the person being photographed or the photographer himself moved when the shutter button was about to be pressed.

The subject is shaking. Although the subject’s headgear seems to be in focus, the face appears to be double-imaged as if multiple exposures were used.

This is because the shutter speed is too slow and the character's movements are not frozen.

Many photos that are considered out of focus are actually failures caused by shake. If you carefully observe those photos that are considered out of focus, you will find that many of the images are not sharp enough because of shake.

Defocus and shake are basically unrelated, but they will affect the sharpness of the photo.

Pay special attention to this when taking portrait photos.

In addition, you should also pay attention to the subject shake that may occur at the same time as hand shake.

As a benchmark for shutter speed that does not cause hand shake, it is generally believed that 1/focal length = safe shutter speed, but this statement does not take into account the impact of subject shake.

When taking portrait photos, you should consider that the person being photographed is also moving, and you should decide on an appropriate shutter speed based on this.

Principle 2 of portrait photography. Telephoto shooting shows the unique charm of portrait photography. 1. The benefits of taking portraits with long focal length. Today I will introduce to you the advantages of shooting portraits with medium and long focal lengths.

The choice of focal length directly affects the proportion of the subject in the picture, thus determining the visual effect of the photo.

The reason is that it is easy to use. The zoom lens can zoom in or zoom out the scene being photographed. This is of course a simple composition, but it is by no means the best way to take portraits.

The advantage of using a medium telephoto lens is that the photos taken have less distortion, normal perspective, and are easy to operate.

Because its shooting angle is small, the depth of field is shallow, and it has a significant compression effect on the scene, it can blur the messy scene, make the characters more prominent, and the picture more stable.

2. Experience on using telephoto lenses Telephoto lenses can bring people and scenery in the distance closer, strongly compress the space, making the picture quite concise, compact and full, blurring the foreground and background, highlighting the subject, and significantly weakening the perspective effect.

On the basis of obtaining the beauty of the superimposed scenery.
