Movie shooting - Movie shooting

Movie recording options on digital cameras.

13. N

Neutral - Neutral

This option has a color saturation, image contrast and moderate image detail, giving more parts for post-editing.

Noise - Particle noise

Coarse grain conditions appear on low-quality images, often due to shooting in low-light situations and with too high ISO speeds.

Normal lens - Medium lens

With a full-frame digital SLR camera, the lens has a 50mm focal length called an average lens.

14. O

One - shot autofocus - Auto focus once

The autofocus mode fixes only one focus when lightly pressing the shutter button (half of the trigger), does not change the focus focus when the subject moves like a continuous focus.

Over - exposure - Du am bright

The image condition is brighter than the scene shot in actual view, which occurs when the amount of light entering the image sensor is more than the exposure required.

15. P

Panning - Lathe

A technique of capturing moving subjects while shooting and moving the camera to the subject with a slow shutter speed. Subjects in the image are still in the clear image area highlighted on the blurred background.

Partial metering mode - Partial metering mode

Perspective - Perspective

Textures of different distant objects in the frame. For example, when shooting with a wide-angle tube, the subjects near the eyes may feel larger and the distant object is very small.

Picture style - Picture style

In the camera there are image style options like this: Standard (standard), Portrait (Portrait), Landscape ( Landscape ), Neutral ( Neutral ), Faithful (Honest), Monochrome ( Monochrome ). These options are pre-designed to suit each type of image. Users can create their own image style by tweaking the color, contrast . inside or capturing RAW (raw) image and post-production as desired.

Pixel - Pixel

The camera's image sensor surface has small light points called pixels.

Pixel count - Number of pixels

The number of pixels that an image sensor has, such as a camera with an 18 MP image sensor (megapixel), will have 18 million pixels capable of capturing light when shooting.

Portrait - Portrait

Picture style in camera image style options. This style when taking portraits will have a lighter and lighter skin color than other styles.

Prime lens - Focus lens

Is the lens with a fixed focal length, does not change the focal length like a zoom lens (multi-focal length).

Program / Program AE - Auto exposure mode

It is an automatic exposure mode of P / AE, which means that the machine automatically selects the lens aperture, shutter speed based on metering information. Users can only set exposure compensation, ISO speed, white balance, flash.

Is the standard shooting option, not in favor of other shooting styles such as landscapes, portraits .

Subject - Subject

As the main subject of the image to highlight in the scene, is the person or thing that the photographer wants to capture.

Subject blur - Blurred subject

The situation often occurs because shooting with a slow shutter speed in low light, or a fast-moving subject whose shutter speed is not fast enough to catch focus.

18. T

Tele / Telephoto / Super telephoto lens - Super telephoto / super telephoto lens

Is a lens with focal length above 50mm. This type of lens is effective when shooting distant objects that are closer to see, with a depth of field, close to each other .

22. Z

Zoom lens - Zoom lens

As a lens can change the focal length to a certain extent. For example, an 18-55mm zoom lens, users can rotate the zoom ring on the lens to change the focus in the range of 18 - 55mm.

35mm format - 35mm format

Is the film sheet format in cameras using wide-width film of 24mm x 36mm.

35mm format equivalent - Equivalent to 35mm format

The viewing angle of the lens depends on the focal length and the image sensor size. The viewing angle of the lens changes when the sensor size changes so the 35mm format equivalent focal length is most familiar to users from the selected movie camera. For example, the APSC size sensor has a 1.5x crop, the 35mm-format equivalent lens length will be calculated by multiplying the focal length by 1.5.
