Basic knowledge of wedding photographers

Basic knowledge of wedding photographers

Wedding photography refers to the whole process of documentary shooting at the wedding scene, recording all the joys and moods of the whole day, from the bride's makeup in the morning to the groom's wedding banquet, ceremony and dinner. The following is the basic knowledge of wedding photographers, hoping to provide practical help to wedding photographers. Let's take a look at the knowledge theory with me!

Judgment and Selection of Light in Portrait Photography

Illumination field of view: 5 meters wide and 7 meters long, where a= the angle between light and the optical axis of the camera.

Front light: the light irradiated from 0 degree direction is called front light; Divergent light: the light that shines on people from the back of the camera at about 0 degrees; Front light: from camera side a

Triangular light: also known as Rembrandt light, a & gt60 degrees, A.

Also known as cloudy sunshine, the light that shines at a=90 degrees from one side of the camera; Side backlight: a & gt90 degrees, A

The camera and the subject are in line.

Light distribution and exposure in illumination field

Theoretically speaking, beauty comes before light, main light comes before auxiliary light, background light comes after effect light.

Illustration of bare lamp position: A is the angle between light and horizontal plane.

When a=60 degrees, it is called high light level, also called butterfly light; When a=90 degrees, the top light is stereoscopic; A=45 degrees is a common lamp position called portrait lamp; When a=30 degrees, it is called low light level; When α= 0 degree

It's called a foot lamp, which is used to eliminate laugh lines and nose shadows and illuminate the chest and chin.

Light quality composition

First, the main light (also known as shaping light, responsible for the main lighting tasks)

1) Other lights should match the main light, and the ratio of main light to auxiliary light should be between 1: 2 1: 4.

2) The main light can be one or several, depending on the characters.

3) Choose different lighting power intensity according to different scenes and different compositions.

Second, the auxiliary light.

1) auxiliary main lighting, showing the bright skin color of the characters.

2) Improve the brightness and control the light ratio and contrast.

3) The auxiliary light is soft and cannot be greater than the brightness of the main light.

4) There can be one or two auxiliary lights.

Third, side light.

1) Light with bright spots on the edge of the character.

2) The outline features that express the beauty of characters.

3) It is used to distinguish the subject from the background and enhance the artistic atmosphere and texture.

Fourth, the background light

1) The light shining on the background should show a sense of space.

2) The background light can be single light, multi-light and color.

Verb (abbreviation of verb) decorative lamp

1) The intensity of modified light cannot exceed the main light.

2) The direction is consistent with the main light.

3) The color temperature and light quality are the same as the main light.

Understanding of light effect

Step 1: Turn on the main light.

1. Is the modeling effect formed by light and shade distribution ideal? The beautiful part is in the bright part and the ugly part is in the dark part.

2. Whether the projection position and length are appropriate, including the projection of face, nose and body shape.

3. Is the position of the dividing line between light and shade appropriate?

4, nose, eye window performance is ideal.

Step 2: Auxiliary lights

1, which illuminates the dark part and shows the level of the dark part.

2. Control the light ratio, control the tone of the picture, enlarge the black and white, and reduce the color.

3, according to a low profile:? Precious as gold? , high profile:? Cherish black as gold?

Step 3: Side light

1, it's better to hit the noodles than to hit the line, and the strength depends on experience.

2, the light quality can be hard, such as beehives, pill lights, yellow hair and other characters are slightly weaker.

Step 4: Background light

1. Determine the light consumption of the background according to different colors and tones.

2. Draw at shoulder height, and play the gradient lamp holder upwards.

Step 5: Decorate the lamp with cloth (only use cloth if necessary).

Highlight brightness and space.

Light source, color temperature, index and comparison table

Color temperature of light source

The clear sky is blue at 10000k20000k and 20000k.

Blue sky 8000k 10000k

The average sky is 7000k K.

Sunlight 6500 penetrates through thin clouds (near the best light)

The average sunshine in summer show is 5500k5600k(9: 00, 10, 16, 18 is the best sunshine).

The sunshine is 4000k5000k in the morning and evening.

Sunrise and sunset 2000k3000k (orange)

The standard index of studio lights and electronic flashing lights is about 5500 K.

Quartz lamp and iodine tungsten lamp 3300k yellow orange.

Photographic tungsten lamp 3200k red orange

At 150w, the tungsten lamp 2800k 1800k is red and orange.

Candlelight 1930k

In the moonlight, it is blue before dawn, red and orange in the morning and yellow and orange at night.

Portrait photography composition

Composition is the position of management, the structure and combination of the picture, and composition is subtraction, which pays attention to the impact of the picture and makes the subject more.

Different, from rigor to adaptation, and finally to the realm of freedom.

Close-up: Above the chest, it shows the facial feeling of the characters, suitable for people with dignified faces.

Chest circumference: below the chest and above the waist, pay attention to the relationship between hands and feet and show the inner world of the characters.

Seven parts: between the knee joint and the calf, mainly showing body shape and hand shape, full of changes.

Whole body: all the characters are presented, the characters and backgrounds are reasonable, and the posture lines of the characters should be beautiful.

Triangular composition: gives people a sense of stability.

Radioactive composition: there is a sense of concentration and dispersion, but the lines all point to the visual center or theme.

S-shaped composition: artistic and mysterious, giving people a sense of secluded lines and winding paths.

Vertical composition: gives people a traditional and steady feeling.

Inverted triangle composition: unstable, but powerful.

L-shaped composition: this composition should leave visual space. When the space is non-visual space, appropriate props should be selected to make up for it.

For triangle composition: there is a sense of momentum.

Tick-tac-toe composition: also known as golden section composition, where is the visual center? Hmm? Box position of words

Circular composition: the main body is circular.

Arbitrary composition: comprehensive and changeable
