How to learn photography systematically

Forcing yourself to recite your own photography is awesome! ! A complete collection of photographic terms—

Telephoto lens:

200mm and 300mm telephoto lenses can be used to shoot birds, lotus flowers and moving objects, and those not far away can also "hit". Therefore, this kind of focal length lens is also called telescopic lens or telephoto lens, which is mostly used to shoot distant scenes.

Ultra telephoto lens:

A lens with a focal length of more than 300mm is suitable for shooting wildlife and sports. It is also suitable for taking close-ups of sunrise, sunset, full moon and string moon.

Macro lens:

Macro lens is a kind of lens that can focus very close to the subject. The size of the image formed by macro lens on film or sensor is almost equal to the size of the object itself.

Standard wide angle

24~28mm is a relatively standard wide-angle focal length, which is mainly used to shoot scenery.

Small spittoon:

Canon EF50mmF/ 1.8 lens.

Dog head:

Finger-covering machine lens, entry-level lens, and canon 18-55mm is more representative.

Cookie head:

Refers to a SLR lens, which is very thin and similar to a biscuit head. The maximum aperture is generally only F2.4-2.8.

Zeiss lens:

At present, Zeiss SLR lenses mainly include Classic, Milvus and Otus, but they are all more expensive.

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.

Shutter:

Shutter is a device for controlling exposure time in 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.

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.

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.

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.

Red eye:

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.

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.

Focal length:

Focal length refers to the distance from the optical center of the lens to the imaging plane, and the unit is mm (millimeter), which is similar to the distance from the lens to the retina of human eyes and is one of the key parameters affecting imaging.
