A method of photographing in which prints made on silver bromide paper are subjected to a chemical bleaching and hardening process before having an oil pigment put to them. From the time of its inception in 1907 until the 1930s, it was widely used by photographers who adhered to the Pictorialist movement.

The brightness of the darkest area of the subject is significantly lower than the brightness of the brightest part of the subject, and this is the difference between the two. Alternately referred to as the Subject Brightness Range (SBR).

A technique that takes a series of images, each of which has a slightly different exposure setting than the one that came before it. This increases the chances of getting the exposure right. See also "auto-bracketing"

Method of lighting a subject with a flashgun at an angle so that the light is reflected off of an object such as a wall, ceiling, or other reflector. This causes the illumination to be scattered, which results in a lighting effect that is softer.

This phrase is used to describe the aesthetic quality of the blur in out-of-focus parts of an image or the lens that creates them. It is derived from the Japanese word for blur. The term "excellent bokeh" refers to highlights that are out of focus yet have a circular shape.

The term "blown out" refers to parts of a photograph that have an excessive amount of exposure to light. They will be bleached to a white color and do not retain any of the detail.

Blending modes are what define how the pixels on one layer interact with the pixels on other layers that are underneath it, as opposed to simply covering them up. When it comes to editing photos, certain blending modes are far more helpful than others. Screen is used to lighten a picture, while Multiply is used to darken it. Overlay and Soft Light are used to improve contrast in an image.

The rate at which data is acquired when a video is being recorded, which can provide as a crude but still somewhat helpful indication to the quality of the film that is being recorded. High bitrates require more powerful cameras and additional storage capacity, but the end result is video of higher quality with fewer compression artifacts.

The amount of bits that are utilized while storing the color information for a single pixel. Digital cameras typically use a minimum of eight bits for each of the red, green, and blue channels, which results in a depth of 24 bits and a theoretical color space of 16,700,000 shades. When set to record in raw shooting mode, the majority of digital SLR cameras provide access to larger bit depths.

The fundamental building block of any and all digitally stored information, also known simply as a bit. Each bit can take on the value of either 0 or 1, depending on its position. Bytes, which are units of measurement for the size of digital files, are typically constructed out of eight bits each.

A light-proof and flexible tube that can be folded into a concertina shape that is used to separate a lens from the body of a camera. The use of bellows on cameras dates back to the middle of the 19th century, and this technology is still in use on large-format equipment today. They have a swing and tilt mechanism that enables the plane of focus to be adjusted to the desired position. In order to make more finely adjusted macro photographs, bellows are often employed instead of extension rings on single-lens reflex cameras.

A lighting gadget that is used in portrait and fashion photography to create an effect that is flattering to the subject. It is made up of a big reflector in the shape of a circular dish that is typically between 40 and 50 centimeters in diameter and has a light source situated in the middle of it. The lamp will typically have an opaque cover, which ensures that the subject will only be illuminated by the diffused light reflected from the dish.

When photographing with wide-angle lenses, you may notice a lens flaw or aberration known as barrel distortion. This aberration causes straight, parallel lines in a picture to bow outward, which can be seen in the image. The greater the lens's field of view, the more severe the distortion. The result is visually comparable to the impression that would be achieved by wrapping an image around a cylindrical object. It is possible to make the necessary adjustments in the post-capture editing software.

There are four doors on hinges that are attached to the front of the studio lights. The shape of the light can be altered, as well as its direction, by using the doors.

A particular variety of tripod head in which the head mount, which is responsible for holding the camera, is connected to a ball-and-socket joint. When the ball lock knob is turned clockwise, it tightens the socket, which in turn locks the head in place.

A backup is a copy of a digital file that is stored in case the original digital picture becomes corrupted or is lost.

When the light source is on the other side of the subject from the camera, the resulting image has what is known as backlighting. It indicates that the area behind the subject is receiving a greater amount of light than the area directly in front of the subject. In order to heighten the drama of a subject, to create a silhouette or rim-lighting effect, or to isolate the subject from the background, this technique is frequently utilized.

White balance adjustment on autopilot This is a system that can automatically alter the color balance of an image to make it look as realistic as possible to the human eye, taking into account the color temperature of the light source.

Some cameras have a feature that automatically takes a series of images at slightly varied shutter speeds (or aperture settings) from the 'proper exposure' If you doubt the meter reading for a particular subject, use this function. It can also photograph a high dynamic range sequence. HDR Some cameras have autoflash, ISO, and white balance bracketing.

Astrophotography is a type of photography that involves attaching a camera to a telescope in order to take pictures of astronomical objects in the night sky. Examples of these items include the moon, stars, planets, and comets. By employing exposure times that are very lengthy, astrophotography can also be utilized to record astronomical phenomena that are not visible to the naked eye.
