How to use up the light when shooting?

Excellent photographic works need planning, and using light is the basis of planning. Therefore, the most important part of the perfect use of light occurs before turning on the first lamp. The planning of a photographic work may take many days, or it may happen a fraction of a second before pressing the shutter. It doesn't matter when and how long you plan it, as long as you plan it. If you do more with your brain, you will do less with your hands, and your thoughts will always be faster than your actions. It is very important to understand these principles of light use, so that we can know where the lights need to be placed and then arrange them. The rest is the fine-tuning of photography. Tool materials: SLR camera, flash, battery, memory card.

The best time for outdoor shooting: from sunrise to sunset, not only the position of light changes at all times, but also the intensity of light changes with time. Therefore, the light effect of natural light on the main body of the character will change with the change of the position and intensity of the sun. In view of the diversity of natural light, photographers need to choose the best outdoor shooting time when taking outdoor portrait photography to obtain the most satisfactory portrait effect. Generally speaking, the best shooting time in a day is before 10 am and after 3pm (provided that it is after sunrise and before sunset). At this time, the light of the sun is soft and moderate, which can make the characters present a natural state. Generally speaking, in a light source with high color temperature, there are more blue light components than red light; In a light source with low color temperature, there are more red light components than blue light. Also during the day, the color temperature of sunlight changes at different time periods. For example, the color temperature of sunlight at sunrise or sunset is relatively low, about 2000 ~ 3000 K, about 4000 ~ 5000 K in the morning or afternoon, and about 5500K around noon. Therefore, when choosing the best time for outdoor photography, the overall feeling of the portrait photos taken is easy to produce a warm orange-red tone (the effect is more obvious when shooting sunrise or sunset), thus giving people a warm feeling.
