An image with high contrast and harsh tones.
The part of the computer that stores all the programs and files. Additional hard drives can be added to increase storage space.
Used to describe the task of linking computer accessories such as hard disks and scanners to a connection such as a SCSI port on a computer.
Automatically joining segments of data that have been split when saved on the hard disk. Doing this tidies up the drive and creates more space.
A computer device that can use storage media like floppy disks, hard disks or optical disks.
A flexible magnetically-sensitive disc that's held inside a 3.5inch square hard plastic case. It has a storage capacity of 1.4Mb which is ideal for transporting text or low resolution or highly compressed digital images. The format is gradually becoming antiquated as advanced storage options such as removable media compete.
An attachment for studio flash that looks like a honeycomb mesh and is used to obtain a hard lighting effect with distinct shadows.
A portable hard drive such as a Zip drive or Magneto Optical that uses removable cartridges to hold data. Zip disks are either 100 or 250Mb while magneto optical are 230Mb, 640Mb or 1.3Gb. The disks can be reused and are ideal for backing up and transporting large digital images.
A universal type of connector, pronounced skuzzy that’s used to attach external peripherals, such as hard drives and scanners, to a computer. Most SCSI adaptors will allow up to seven items to be connected in a chain, providing they each have a different ID number which can be selected independently on each device. This method of connection can be troublesome and is slowly being superceded by USB and Firewire.
A computer with a huge hard drive that is used in offices to store large quantities of files that can be accessed by several computers joined in a network. Its also used by ISP companies to look after subscribers web sites.
This is how much data (usually indicated in megabytes [MB]) that can be stored on either a hard drive or a drive's removable media disks.
Used to balance the light of a scene with overly bright highlights. There are physical filters to use in front of a camera lens, and digital filters for use in imaging software. A physical graduated neutral density filter, for instance, has one clear edge and then gradually increases in density towards the other edge. A so-called "hard grad" has a graduated section that reaches the middle of the filter, whereas a "soft grad" has a graduation all from one side to the opposite side. Neutral density graduated filters are the most common types, but there are also coloured versions available - gradient sunset filters, for instance, or tobacco-coloured ones. Physical filters are usually square or rectangular, are used in a filter holder that attaches to an adapter ring, which screws into the front of the camera lens. Sizes depend on the diameter of the front of the lens. Gradient filters can also be applied digitally in photo editing programs. Even when this is not a standard option in the program, often a so-called "plug-in" can be used for use in the program.
