It is a process which allows a light to act on a photo sensitive material. The amount of exposure depends on both the intensity of light and the time is allowed to act on the sensitive material.
Extension Ring or Tubes:
It is a space ring which fits between the camera body and the lens, allowing the camera to focus on subjects close-up than the nearest marked focusing of the distance.

It is a point where maximum coverage is made through the lens.
The distance between the length and focal point is known as focal length.
The point either side where light rays entering parallel to axis coverage.
The film that is very sensitive to light that required only small exposure. These are ideal for photography in dim light condition in places where faster shutter speed is desired.
For taking photographs in poor lighting conditions flash unit is used. It is a unit having source of high intensity of light connected to the camera mechanism with a cord. The flash light goes off for short period when the shutter is released.

Floods the screen or areas with shadow less light is called key light.
One of the most important and yet undervalued accessory is the lens hood which could be attached in the front of the lens either by using the fitter thread or some form of bayonet mount. The primary function of a lens hood is to improve the picture contrast by shielding the front element from stray light and to prevent glare caused by this stray light around the lens.
Shooting pictures in poor light which needs an exposure lesser than 1/30 second, is called Low Light Photography.
Long Focus Lens:

Any lens which corporate mirrors instead of conventional glass or plastic lens elements. This type of lens designed and employed mainly for long focal length lenses.
In contact printing a mask is used in between the negative and the contact paper to produces white border in the print. This mask is nothing but the black paper with a neatly cut opening of the same is slightly smaller areas than the picture.
It is otherwise called standard lens. When you purchase a camera any lens permanently fixed to the camera body for the camera is known as normal lens.
Neutral Density Filter:
The filter placed in front of the camera which reduces the amount of light reaching the film without altering the light is called as neutral density filters.
Over exposure is exposing the film or paper beyond the normal or correct exposure which occurs because of lack of light which in turn reduces the image quality.

Single Lens Reflector camera views the subject through the lens via a mirror.
Sky Light Filter:
In daylight on overcast in open shade at high altitudes, there is a high proportion of ultra violet and blue light. So when pictures were captured the outcome might be with all bluish cast. Ultra violet or sky light filters which is slightly pink or neutral in appearance will restore the colour balance in such situations.
Slave unit is a small photo electric cell, mounted on the cordless additional flash unit kept in a usable position away from the camera. This flash with the slave unit is used in addition to the main unit mounted on the camera where the main flash fires. This light triggers the additional flash through the photo cell in the slave unit.
Soft Focal Lens:
A lens designed to give slightly sharp images. This type of lens was used primarily for Portrait and the results may not be as same conventional lens.
It is in powder form with white irregular crystals. This is a weak alkali soluble, which makes the developing agents more and more active and hence called as accelerator.
This is a white crystal water soluble substance used as a preservative.
When you are using flash unit, the flash light comes on and goes off for a very short period when the shutter is released. It is important that the firing of flash and the opening of the shutter happens at the same instance so that the subject is captured properly when the shutter opens and closes. This is called 'Flash Synchronization'.
Telephoto Lenses with focal length of 200mm or longer are bulky besides being slower in speed due to large aperture like f4 or f5.6 consequently, depth of field is shallow.

To avoid wastage of costly printing paper you should expose the given paper properly. Also you should select the grade of the paper correctly to suit the negative. This can be done by first taking the test print. The test print can be done only by a small bit of print paper placed over the negative. This is called test bit.
It is a control system which modern flash gun is having. It saves energy consumption and also automatically adjusts the output for special range of distance.
The visual impact of an image can be increased by a chemical process called toning. By chemical treatment the black and white image is replaced by coloured image.
This type of film directly produces colour slides positive figure in the film that can be looked through a viewer on to a screen using a slide projector.
This is an interesting photography. There are optical tricks, mechanical tricks given to the establishment process and special effects corrected this is known as trick shot.
Ultra Violet Filter:
Ultra Violet rays are not visible to our eyes but affect both colour and black & white film. Open seashore, sunrises, landscapes high altitude areas extensively reflect UV rays present in daylight, thereby reducing the quality of the images formed on the film resulting in poor contrast, haziness and excessive blue. The UV filter absorbs this radiation, improving the over all image quality and colour saturations.
In sufficient exposure of film or paper which reduces the contrast and density of the image.
A simple optical device usually indicates the edges of the image being formed on the film.
