Standard lens:

Usually the 50m lens (on a full-frame sensor camera) is considered the standard lens because it is closest to what the human eye sees. The 35m lens is the closest to what the human eye can see on a half-frame camera.

Telephoto lens:

To put it simply, a telephoto lens is longer than an ordinary lens, such as 70-300mm. A lens with a longer than standard focal length, giving a narrow field of view and a magnified image. Super telephotos are usually 300m and longer lenses.

Wide-angle lens:

Shows a wider field of view than a standard lens, allowing for a wider scene. Depending on the degree of wide angle, there may also be edge distortion (super wide angle), and if it becomes wide enough, the image will become rounded (fisheye).

Tilt-shift lens:

Try to recreate the available movement of the lens when using the view camera. Being able to tilt the front lens element allows the focal plane to be readjusted. Allows the subject's position within the frame to be adjusted without tilting the camera, thus keeping parallel lines from converging. This is a popular lens for architecture and landscape photographers, and is being widely used by portrait photographers to create unique stylized photos.

Noise:

When the ISO setting is too high, small grains will appear in the photos taken.

Contrast:

Contrast refers to the contrast between light and dark in a picture.

Lighting ratio:

The ratio between the intensity (brightness) of the key light and the fill light is the difference between the bright and shadow edges of the subject's face.

Flash:

A small, portable flash that can be attached to your camera's hot shoe or used independently when activated remotely.

Reflector:

A device used to reflect light, usually towards a subject. It can be a factory-made reflective panel for a specialized door (a 5-in-1 is recommended) or a piece of white cardboard.

[Lens focal length vocabulary (35mm full-frame system)]

Fixed focus lens = lens with fixed focal length

Zoom lens = lens with variable focal length value.

Header = fixed focal length head with standard focal length-50mm focal length value. On the 135mm system, the angle of view at this focal length is close to the angle of view of the human eye, so it is called a standard lens, or a header for short.

Standard zoom = standard zoom lens, covering zoom lenses with standard focal length (50nm), for example 24-70/24-120.80-90% of the photos were taken with this range of focal length.

Fisheye = 10~14mm focal length, extremely wide viewing angle, exaggerated deformation, and very exaggerated and exciting visual effects.

Ultra wide angle = 14mm23mm focal length, mostly used for landscape shooting of large scenes.

Wide angle=24mm~35mm focal length.

Medium focus = 35-70mm focal length, close to the human perspective.

Medium telephoto = 70mm~135mm focal length.

Exposure:

The total amount of light reaching the digital sensor. Controlled by setting aperture, shutter speed and IS0. The principles and usage of these three parameters have been explained in detail in my previous position.

ISO:

Represents the sensitivity of the camera's digital sensor to light. The lower the number (1S0100), the less sensitive it is, and the higher the number (IS03200), the more sensitive it is. A higher IS0 allows shooting in low light conditions.

Shutter speed:

How long the shutter is open during the exposure. Use fast speeds (such as 1/2000 second) to freeze motion, or slow speeds (1/4 second or longer) to blur moving objects.

Fixed focus lens:

Any lens that does not focus has a set focal length, such as a 50mm lens. A variable opening in the head through which light enters the film or digital sensor. Measured in value units. I like to compare it to your pupils, which open and close based on the brightness level of the room to allow more or less light into your eye.

Macro lens:

A lens taken very close to a subject, allowing a 1:1 reproduction of the object's size or larger.

Cable release or timer:

A device that triggers the camera's shutter door without pressing a button or touching the camera. Helps eliminate camera shake during long exposures.

Aperture:

The variable opening in a lens through which light enters the film or digital sensor. Measured in value units. I like to compare it to your pupils, which open and close based on the brightness level of the room to allow more or less light into your eye.

Exposure Bracketing:

Capture a series of images at different exposures or EVs. You may see a setting on your camera that is set to AEB (Automatic Exposure Bracketing). This is typically used when creating HDR images, or in difficult lighting situations where you may want to have a range of exposures from light to dark.

Bulb:

The "B" setting on your camera will keep the shutter open as long as the shutter button is pressed or pressed with a camera. On a Canon this may be on the mode dial on top of the camera, or at the low end of the shutter speed setting, similar on Nikon, refer to the manual for details.

EV:

Exposure value is a number that represents various combinations of aperture and speed that can produce the same exposure effect.

Exposure compensation:

Modify the speed or aperture according to the camera's recommended metering parameters to produce a specific effect (overexposure or underexposure), usually used in fast priority or aperture priority mode. Indicated by a small +/button on the camera. The camera reads the light reflected from the subject. When photographing subjects that are lighter or darker than 18% gray, you can use this setting to tell the camera the correct exposure value. The rule is white plus black minus.

Camera mode:

Manual: fully manual setting of SO, shutter speed and aperture. Fast priority (TV on Canon or S on Nikon) users can manually select S0 and shutter speed, and the camera automatically selects aperture for correct exposure. Aperture priority (AV for Canon users, A for Nikon) The photographer selects ISO and aperture, and the camera selects shutter speed.

F-stop:

is a measure of the opening of the aperture in a lens, defined by dividing the focal length of the lens by the aperture. The order of f-stops is a multiple of the square root of 2 (1.414...); 1.1.4, 2.2.8, 4.5.6, 8, 1116, 22, etc. Although these numbers are quite arcane, remember that each step is twice the amount of light.

Ambient light:

Also known as available light, is the light that occurs in the scene without adding any flash or light modifiers. This may be daylight, or artificial light such as tungsten or fluorescent light bulbs.

Key light:

Is the main light source of the photo. It could be the sun, a studio strobe, a speedlight, a reflector or something else. But it is the source of light.

Fill light:

It is the light source second only to the main light. It is mainly used to "fill in" the shadow. It can be done by using flash, reflector etc.

Lighting Pattern:

This is the way the light hits the subject’s face, creating a specific pattern of light and shadow.

Telephoto = 135~200mm focal length.

Portrait lens = lens with a focal length of 85mm~135mm. This type of lens is suitable for taking close-ups of portraits.

Baiwei = a macro head with a focal length of about 100mm. For example: Canon 100 mm Macro/Nikon AF-S105 mm VR Macro.

Super telephoto/telephoto = 200mm or above focal length.

Cannon = usually refers to a lens with a long focal length of more than 200mm, a large aperture, and a large volume.
