What is the difference between led fill light and flash
A fill light is a luminaire used to compensate for certain lighting or equipment due to lack of illumination. At present, there are usually three kinds of fill light, one is the camera greenhouse fill light (also called plant fill light), the photography fill light (also called photography light or camera fill light), license plate fill light ( Also called white light).
supplement:
Camera fill light is also called camera light, headlights, news lights, and so on. Its main function is to provide auxiliary light when shooting in the absence of light conditions to get a reasonable picture material. The camera fill light has excellent control performance such as adjusting brightness, color temperature, and displaying remaining power.
The license plate fill light mainly cooperates with the camera to achieve the purpose of seeing the license plate. It is the auxiliary light source of the license plate, also called the white light fill light. It is mainly used for road monitoring fill light, parking lot entrance and exit license plate fill light, community entrance and exit license plate fill light, etc. The place where the license plate is filled with light.
It is one of the ways to increase the exposure, especially in dimly lit areas, and the flash can help make the scene brighter. Chinese is called "electronic flash", also known as high-speed flash. The electronic flash stores high voltage through a capacitor, and the pulse triggers to discharge the flash tube to complete the flash. The color temperature of a typical electronic flash is about 5500K, which is close to the color temperature of the daytime sunlight. The luminous properties are cold light type, suitable for shooting objects that are hot.
The flash light emits a strong light in a short period of time and is a photographic-sensitive photographic accessory. It is mostly used for instant illumination in dark lighting situations, and also used to partially fill the subject when the light is bright. The utility model has the advantages of small size, safe use, convenient carrying and stable performance.
The flash can be divided into three categories according to its type and its function and performance.
1. Built-in flash, using the built-in flash will cause a lot of power consumption of the camera, and the built-in flash does not support the various advanced functions of the flash.
2, external flash, external flash is generally located at the top of the camera body, some high-end external flash also provides a variety of advanced features.
3, handle flash, handle flash is often used in photo studios, photo studios, wedding photography studios and other professional places.
4, electronic police flash
The flash is a fill-in device that ensures clear and bright images in dim conditions. When shooting outdoors, the flash can also be used as an auxiliary light source to emphasize the tone of the skin. Special effects can also be arranged according to the photographer's requirements.
1: Change the color temperature.
2: Improve subject lighting conditions 3: Reflect light, do not destroy the scene environment 4: Add eye light 5: Multi-light combination, shape the image of the subject 6: Reduce or increase contrast 7: Instant solidification Camera 8: Fill light
Select LED according to the phone flash application
Although there are no packaging and electronic standards in the flash LED field, manufacturers have defined many LED components for camera flash applications. When designing an LED flash in a camera phone, the criteria to consider are:
Optical characteristics
2. Electronic design simplicity and flexibility;
3. Pulse modulation function;
4. Can be effectively cascaded to get higher light output;
5. Heat dissipation considerations;
6. Manufacturing and assembly considerations. Especially the compatibility of LED modules with the manufacturing process used by camera phones
1 from the naked eye, the LED is always bright, continuous uninterrupted light source, the flash is able to emit a strong light in a short time to instantly fill the light;
2 In terms of appearance, led is composed of a row of lamp beads, which is a large luminous matrix, and the flash bulb has only one lamp;
3 From the duration of the shooting, the led is always bright, it will always be on until the power is off, the flash is instantaneous, only the shooting moment will blingbling, flashing the dog's eyes.
4 From the illumination area, although the LED lamp has a relatively large light-emitting matrix, its LED lamp illumination area and brightness are limited, so the larger the plate with the led lamp, the more the lamp bead, the brighter it is. And the brightness of led is related to something called "lumen". This thing called "lumen" is actually a unit of luminous flux. The bigger the lumen, the brighter the light is and it is continuous.
The brightness of the flash, if it is calculated in a flash, is actually much brighter than the led, and the illumination area is much larger. This is because the two lamps are not constructed in the same way.
Therefore, the led illumination area is relatively small compared to the flash, and the brightness in a moment is also smaller than the flash.
Led is a continuous light source, the flash is not continuous.
What you see as a led light is what you get, and what the flash is like is not known until the shutter is pressed.
The led light can be used as an auxiliary light source, because it is WYSIWYG, but when shooting a large scene (such as multi-person or wide-angle shooting large scene), led light is not enough, it is recommended to use the flash.
Photographing is an instant art, which is why I would recommend a newcomer with insufficient budget to buy a flash instead of a led light. Because I want a better shot, the price of the led light is not very cheap.
If you like to play videos, it is recommended to buy led lights. If you don't like the budget, don't buy them.
Playing with lights is the art of light. It is to burn out the money, and the novices are careful to enter the pit.
