Photography is both an art and a technique . Why is it art , Because photography contains two elements of composition and light . Composition is how our subject and content are represented in the picture ; Light represents light and shade and different colors , The change of light can be used to express emotions , Set off a different atmosphere .Tomas The teacher's main topic in this class is the composition of art and light .
The basic principles of composition ：
- Determine the subject and theme before shooting （ A flower 、 A person 、 A mountain ; The grandeur of the scenery 、 Small bridge, flowing water, people's artistic conception 、 The atmosphere of loneliness ）
- Do well in addition and subtraction ： Add , It is to add the environmental objects to set off the subject ; reduce , It's subtracting the surrounding objects that affect the subject expression .
I know the basic principles of composition , Let's see how to use ：
The beauty of simplicity
For most people , The simplest and most effective way of composition is subtraction , Make an image as simple as possible , Let the subject fill the whole picture . therefore ,Tomas The teacher's advice ： Try to take a simple composition , Abstract an object , A line , A part of , The geometric beauty of a close-up , Let nature's wonderful design or artificial wonderful design naturally show .
The beauty of combination
The trick of putting multiple objects together is to show contrast and conflict , Without contrast, conflict has no characteristics . For example, shooting ten people , Ten people stand in a row , Everyone has no characteristics , This photo is a failure , and 9 A thin man and 1 A fat man , There are conflicts and contrasts ; We take pictures looking for antonyms to combine , The big sets off the small , The movement sets off the stillness , Cold colors set off warm colors , The classic sets off the modern , This will strengthen the contrast , Make great photos .
The beauty of layers
When we learned to photograph simple objects , And master the beauty of contrast and combination , We can put more objects into the picture layer by layer , Create the beauty of levels .
summary ： The core of composition is to discover the beauty of simple objects first , If simple objects can be combined together to form a contrast, the beauty of combination , Just put it together , If different objects can be divided into layers , Make it a grand scene .
Trisection 、 Diagonals 、 Golden ratio 、 Golden spiral
Guide line ： Use the natural lines in the photo as the guide line , Form a guide line and compose the picture , Common lines, such as a road . Except for the more obvious guiding lines like lines , There are also some obscure guides , For example, a person points to a certain direction or a person's line of sight .
We get the subject of the picture by composition , If we want to attach emotion or attitude , You need to make good use of the light . The light is different Texture , Divided into soft light 、 Hard light .
Hard light ： The light from the strong sun is hard , Hard light forms strong shadows , For tough photos , Like snow mountain and a male character .
Soft light ： Light without shadow on cloudy days is suitable for soft objects , So it's easier to shoot portraits and wedding photos on cloudy days .
The light is divided into different Direction ：
Shun Guang , The light shines on the object in the direction of shooting , Suitable for color expression , But because of the smooth light , Shadows are blocked by objects , No highlights, shadows and boundaries , The picture will be more flat , Lack of three-dimensional sense 、 Texture . And the best way to express the three-dimensional feeling and texture is to use the side light , Make the object in the picture highlight and shadow . It's easier to take photos of scenery with side light .
Backlight shooting is more challenging than downlight and side lighting ,Tomas The teacher shared three backlight shooting techniques .
① Use backlight to take a silhouette of the scene , Highlight the outline of the scene 、 Light and mood .
② When the subject is translucent , We can use backlight to shoot , Common translucent objects , For example, the character's hair 、 Green grass and trees 、 Reeds, etc .
③ At sunrise and sunset , The sun is mild , You can take the sun directly into the picture , It won't cause an explosion .
Deal with all kinds of weather easily
Use different weather to photograph different emotions and atmosphere .
Sunny days are good for high saturation 、 colorful 、 Happy and fairy tale scenes .
cloudy , Take it into the sky and use colorful clouds 、 The ever-changing light shows the magnificence and magic of nature .
Rainy days , Bring your own little freshness 、 Little melancholy 、 Deep feeling , Use freshness 、 Melancholy expression and so on highlights the weather characteristic .
Many people turn their saturation to the highest on cloudy or sunny days , Force out colorful colors （ EH , It's not about Ben Shuai ）, In fact, on cloudy days , We might as well remove the color , To show the unique light and shadow of cloudy day , Low saturation features .
Last Tomas The teacher also talked about the exposure triangle . Take a close shot of a character with a large aperture , Take pictures of the scenery with a small aperture . According to the aperture size , Adjust the shutter and ISO To achieve the final normal exposure , If there is pure white or pure black in the picture , There are over explosion and under explosion . The best way to determine whether the exposure is normal is to use histogram .
Question and answer after class
1、 Shooting people , It's easier to take a bust close-up than a full body
2、 Children who don't know the depth of field of aperture just started with the camera , The best way is to read the camera manual , It is suggested that the children read the camera instructions before reading all kinds of tutorials .
3、 About composition innovation , It seems that there is no difference between the paintings drawn by many children and those by others , But when children draw, they don't know what they are doing , And when we draw, every stroke has its own conception and meaning , Therefore, we suggest that we first follow the traditional composition method for composition , When you're familiar with it , Naturally, you can find the most suitable composition to innovate .
