50 Fixed-focus Lens Tutorial and Experience in Use

50 fixed focus lens is very suitable for taking portraits. Generally speaking, 18-55mm is the standard lens. Usually those who study photography should be suitable for 18-55mm standard lens, but for amateurs and friends who have no foundation at all, choosing 50 fixed-focus lens can shoot the most delicate face and hair of the characters.

step

You can choose a large aperture to shoot close to the subject, and increase F 18 to indicate that it belongs to the aperture. It can blur the background, and the portrait taken by people at close range will be clearer. When shooting portraits, you can choose the sun at 4 pm to shoot, especially in summer, soft light will illuminate people's faces and make them look softer.

Fixed-focus lens shooting usually doesn't take photos by adjusting the lens back and forth like zoom lens. It only needs a focal length lens to blur the background of the photo. Moreover, with the digital SLR camera, it can avoid the jitter of the photo and make the clarity of the photo appear again. Adjust the aperture to 4.0 and the camera mode to P mode, and the most suitable shutter speed will be automatically selected according to the aperture. Through the exposure compensation mode, you can take more layered portrait photos.

The distance between the SLR camera with 50 fixed-focus lens and the portrait should be taken within 2 meters. At the same time, you can choose a fixed-focus lens to take still life photos at night, and light small desk lamps on the left and right sides to shoot colored fluorescent paper, so you can choose perfume bottles to shoot still life, and put some suitable green leaves on them to make the perfume bottles look more transparent and beautiful.

When you choose a 50 fixed-focus lens to shoot with a SLR camera, you can also shoot at close range. Its stability is relatively stable compared with telephoto lens. When shooting, you can capture objects that are afraid of moving, change the camera mode to motion mode, and capture at close range. The effect of photos will be very clear and dynamic. However, when choosing a zoom lens, the stability is not high and you need to shoot with a tripod.

Choose 50 fixed-focus lenses and SLR cameras to shoot portraits. You can turn on the flash in the dark. The built-in flash will flash automatically when shooting indoors. Usually, when the sun just rises at 9: 00 in the morning, you choose to shoot a portrait obliquely against the light, and the face of the portrait will be illuminated. Then, let an assistant cooperate with the reflector and hit the back of the character or the side of the clothes worn by the upper body of the character, so that the face of the character can be photographed more clearly.

When choosing a 50-focus lens to shoot with a SLR camera, the color of the person's clothes should be reasonably matched with the color of the selected background. When shooting a person, a certain distance should be kept between the person and the background, which will make the contrast between the person and the background more prominent. Generally speaking, the background of shooting characters should be concise, and it is also good to choose the lawn as the shooting background.

When you choose a 50-fixed-focus lens to shoot with a SLR camera, you can use a 55-mm fixed-focus lens, set the aperture to 4.0, choose the focus position according to the expression of the character, choose the zoom point, then press the shutter to shoot, fix the focal length, and then adjust the aperture and shutter speed when the character has a big movement. At the same time, if you want to be thinner when shooting portraits, you can shoot portraits through the oblique side.

Experience in using equipment:

1, commonly used fuselage and lens combinations.

I just bought 5D2 in February this year, but I used 600D before. Compared with the two machines, 5D2 is professional and Quan Huafu. Haha, sharpness is also what I want. The picture quality is good. But I always use Sigma's 50, 1.4 lens. I don't know much about the equipment now, mainly because this lens is more affordable. Then, the 50mm angle of view is good and the workmanship is good. I'm used to it, but I think it's enough for now.

There is also a film machine X700 Minolta, 50 1.4 lens.

2, the use of fixed-focus lens experience.

1, mainly cheaper than other fixed-focus lenses. Suitable for beginners. It's also faster to get started.

2. The field of vision is very close to the human eye. Will not deform.

3, 50. 1.4 people, still life is enough, the aperture is generally large enough, and then there are more occasions to use it.

The focus of this Hummer I used is a little poor, but it is easy to get out of focus if the aperture is too large. General 1.8 will do. Then this may be the only deficiency I can feel in this shot.

This lens is used to shoot models. I am used to counting light and then focusing on people's eyes. Then, because it is fixed focus, you have to move your body to find the right angle of view. Maybe this zoom lens will be more worry-free.

This shot should not be suitable for rushing to shoot weddings and major events, because it is a bit too hard to keep you running with the bride all the time.

3. The composition of the fixed-focus lens and the visual effect created.

All my photos were taken at 50 fixed focus. Fixed focus is especially suitable for portraits and still life. Moreover, using fixed focus will remind you to think carefully about the composition method and find the most suitable angle and distance for shooting. 50 1.4 besides taking portraits, you can also take still life and small scenery.

4. How to fix the focus and shoot the backlight in early winter?

When shooting backlight, we must pay attention to the time, place and people. The best time is one hour before sunrise and sunset. Don't try to shoot the backlight when the sun is shining directly at noon. For example, around 4 o'clock in winter is the best shooting time, the sun begins to turn yellow, and then the light spreads softly. If you choose a place, you should choose a place where the site is bright and there is no building shelter. Harmony is to communicate with the model in advance about the feeling of shooting, because the sunset can't waste too much time soon. Then I am used to M-file shooting, spot metering, and the aperture is wide enough. Then you can try to adjust the shutter, and then remember the hood, because glare is easy to appear when backlighting. One more thing, if you want to make the light more yellow, you can set the color temperature of white balance through the camera.

I have often seen that it is better to have a reflector to fill the light and the effect is better. You can try, because I have photographed a person and a model, and I have never tried. If the face is not bright enough after natural exposure, it can be adjusted later.

5. How to shoot a good-looking Jiao Wai?

I usually shoot 50/1.4 shots with a film machine when shooting with a large aperture, because this lens of Sigma is easy to lose focus, and then it is also available in digital Jiao Wai, but it is not as obvious as film shooting.

But on the whole, there is a little trick to shoot beautiful Jiao Wai. Generally, outside the subject, there is light passing through the leaves, and it is easy to form Jiao Wai, even if the aperture is not large enough.

6. How to shoot in dark light?

The last time I took a photo was in a cafe. The room is a little dark, when it is dark. It's best to find a place with a light source, so we chose a window. Although it is dark at night, the light outside the window still shines on the model's face.

Then, with the help of the indoor desk lamp, the lighting is completed. You can light up your face. Like other rooms on the street, be sure to find the main light source, desk lamp, window lamp and street lamp of the environment you want to shoot.

This group is also because it is raining outside, and then there is no other light source indoors. Fortunately, there are two white walls. At this time, you must avoid facing the shadows when shooting. Camera parameters are adjusted. When shooting at ordinary times, I have an idea of the color tone in the later period. This set of iso has reached 1000, and I am very reluctant to do it. But the weather doesn't allow it. I can barely shoot, but fortunately the effect is ok.

7. What is the biggest difference between fixed focus and zoom?

Zoom lens also has its own advantages, but it is still biased towards 50mm fixed focus. There are three problems with zoom lenses.

1, the price is more expensive.

2, the volume is large. Girls use fixed focus more compactly.

3. When it is adjusted to a specific focal length, its imaging is often not as clear and sharp as the best fixed-focus lens.

4, and the fixed-focus aperture at the same price is also large enough.

Shooting skills:

1. How to create an atmosphere for models to enter the role?

Usually, the girls who ask me to take photos will spend an hour communicating when they meet, especially the girls who meet for the first time. If time is tight, I will also tell her roughly how I want to take pictures. Generally speaking, shooting is not in a hurry, and then I rarely ask models to pose, because I think they will be unnatural, so I usually talk about how to sit, how to stand and how to lie down, and then they will find their own feelings. I'm in charge of snapping pictures, and they relax. What I photographed here is their most natural appearance. Also, we should always encourage models to adjust their emotions and finish shooting happily. Why not? I like the present situation, and I can make many friends.

2. How to make better use of fixed focus composition?

A fixed-focus lens requires you to keep moving and thinking to complete the composition. For example, I usually use TIC-tac-toe composition, diagonal composition, vertical composition and curve composition, but I think more consideration is how to express the temperament, mood or best side of the characters when shooting. These composition methods are naturally used when you shoot too much.

3. How to get pregnant before shooting?

Before shooting, I always know the general feeling I want to shoot, and sometimes I improvise in small situations. I use very few props, mainly because there are more people who shoot by themselves, and there are props to better contrast the atmosphere. It is better to match with the clothing itself. There are many props used indoors. Therefore, it is recommended to go to a very literary cafe, because there are many props in it, and it is easy to bring a sense of literature. If the location generally makes good use of natural light, blue sky, white clouds, flowers, grass, trees and things that can be seen everywhere on the roadside, I often use colored balloons.

4. How to make good use of on-site lighting?

I have been shooting with natural light and spotlights. If I want to use light well, I must know the influence of color temperature direction and brightness, and when it is suitable for shooting. The golden stage of a day is one hour after sunrise and before sunset, during which the light diffuses gently. Low angle. Warm colors, although the sunset time is short, will also shoot a good backlight when used well, as well as natural glare. I usually shoot in the afternoon. Backlight shooting has been mentioned above, as well as positive light, 45? Metering 90? Photometry can be taken, and the light sense is also very good. Taking pictures of light, observation is much more important than skill.
