Novice photography terminology

1. Sensitivity

Sensitivity, also known as ISO, refers to the camera's sensitivity to light. The larger the number, the higher the sensitivity, and the more sensitive the camera is to light; The smaller the number, the lower the sensitivity, and the less sensitive the camera is to light. The more exposure, the brighter the picture and the higher the noise, which will affect the picture quality. On the contrary, the lower the ISO, the darker the picture, the less noise, the clearer and more textured it is.

2. Shutter

A device for controlling exposure time in a camera. Generally, the larger the shutter time range, the better. Low seconds is suitable for shooting moving objects and can easily capture fast moving targets. If you want to shoot the traffic at night, the shutter time will be longer, and the silky water flow effect in common photos will also be shot with a slow shutter.

Step 3: Aperture

The aperture is represented by an "f" on the camera, which is used to control the luminous flux of the lens. Every time you open a large aperture, the luminous flux entering the camera will double, and every time you open a small aperture, the luminous flux will be halved.

4. Overexposure

Overexposure refers to the phenomenon that the exposure time is too long due to inaccurate metering. This will distort the color of the picture, lose the details and layering of the highlight area, and make the picture look white. Overexposure will cause irreversible damage to the picture.

5. Eyes are red

When the camera shoots a portrait under the flash, the pupil of the human eye will appear red spots in the photo. Red-eye prevention can alleviate this situation. He will flash in front of the official light to narrow his pupils.

6. focal length

The focal length is expressed as "mm", which is usually marked on the lens, such as 50mm/24-70mm, etc. One number means fixed focus with only one focal length, and two numbers mean variable focal length zoom.

7. Color temperature

The color temperature is represented by k, and the photo color is adjusted by white balance. Because of the different light sources, the color temperature of photos is different. Generally, the color temperature of natural light is 4500 K. The higher the value, the colder and warmer the picture.

8. overexposure

Overexposure refers to the phenomenon that the exposure time is too long due to inaccurate metering. This will distort the color of the picture, lose the details and layering of the highlight area, and make the picture look white. Overexposure will cause irreversible damage to the picture.

9. Color difference

It appears in the area where the dark part and the bright part intersect in the image in the form of color stripes because the lens can't focus all the colors on the same point. It can be adjusted by PS or LR.

10. Out of focus

Out-of-focus refers to the moment when the camera focuses, the reflector turns up, and the camera has a small focusing action before the shutter is opened, so that the focus leaves the original position. It is a bad phenomenon that the camera and the lens chip contact and exchange information.

1 1. Depth of field

Depth of field refers to adjusting the distance between the object and the camera to make the image of the object from blurred to clear, and the aperture controls the depth of field. The smaller the aperture, the greater the depth of field, and the larger the aperture, the smaller the depth of field. And the focal length of the lens will also affect the depth of field of the photo. The longer the focal length of the lens, the smaller the depth of field, and the better the background blur effect.

Exposure rate

Exposure means "brightness of photos". We need to adjust the camera parameters to control the exposure of photos, mainly by adjusting the shutter, aperture, sensitivity and exposure compensation.
