Suggest Term
A term used to describe sending a file via your modem to a Web site, or from the computer back to your digital camera.
A technique used to gain speed with a film. You manually override its ISO speed, using the film speed dial or exposure compensation dial, to make the film more sensitive. To film would then be given longer in the developer.
This is a string of letters and numbers that identify and connect you to a Web site or web page. If you type the wrong thing in by mistake, you may become connected to another site or receive an error message. The URL usually starts with http://www.
Peripheral connector that allows items such as printers, scanners and digital cameras to be connected and unconnected to the computer without turning it off. The computer detects when an item has been plugged in and asks you to install the necessary software if it isn’t already on board. Up to 127 items can be connected at once.
USB 2.0 works in the same way as the original USB standard, and even looks the same. However it uses a much higher bandwidth, up to 40 times faster than the original standard. USB 2.0 also has the advantage of being backwards compatible with existing USB technology, so all your old devices will still work from a USB 2.0-capable system.
A colourless filter thats used to absorb UV light and reduce haze when shooting with black & white film.
Part of the spectrum that has a wavelength below 390nm.
The "brown" in the name of this process gives you some idea of the colour of the finished print -although tones tend to be delicate rather than heavy - so clear, graphic images tend to work best.The process involves combining iron salts with silver nitrate and either oxalic acid for a warm-brown colour or tartaric acid for brown-black result. Tightly-woven fabrics can be a better base than paper, as the finished "print" must be washed in water. Exposure is by contact printing, but, because of the relatively high sensitivity of the medium to light, you should work in dim conditions, and give an exposure of around 1 minute in sunlight.Develop the image in a 1% borax solution, fix it in traditional hypo, and give a final wash of at least 30 minutes.
A lighting control that lets you fine tune the output of flash. This comes in useful when space is limited and you can't move lights back and forth or you want to adjust the exposure of one units when used in a set to balance the exposure.
Black & white printing paper that changes contrast when exposed to different coloured light. A yellow filtered light produces lower contrast, while magenta increases contrast.
The resolution of a monitor or camera CCD that displays or records images with 640x480 pixels.
Some digital cameras have a sequence mode that takes moving images. The length of movie sequence depends on the camera and results can be played back using a movie player like QuickTime and edited using software such as MGIs Video Wave.
Indicates whether the camera can be connected to a TV to view the results. If it has PAL it can be played on UK-televisions or NTSC for US. Image quality looks as good as it would on a computer screen and if the camera has a slide show mode it can be left to run through all the pictures stored in the camera's memory or card.
A medium or large format camera that uses a ground glass screen positioned at the film plane to view the image. Theyre also known as field cameras.
This is what you look through to help point the camera in the right direction when taking a photo. SLR cameras have accurate through the lens viewing so what you see is what the lens sees. Compact, rangefinder and digital cameras have a separate viewfinder that is often less accurate at close range. Some cameras have an adjustment to change the eyepiece to suit your vision. Some have an accessory slot where a small correction lens can be attached.
The position where you take the photograph from.
An image with an edge that gradually fades to black or white. Used mainly by wedding and portrait photographers either created by on-camera filters, using masks in the darkroom or digitally using software.
A graphics card thats built into a computer to control how many colours are seen on the monitor.
A type of finder found on old collectable cameras and most medium format models. The finder has a hood to prevent light reducing contrast as you view directly from the focusing screen. It's called a waist level finder because to use it comfortably you'd hold the camera at waist level.
A black & white print with a brownish tone.
A design that has seals to prevent water finding its way through joins, external controls and screw points. This type of product often has a bulkier bodies but is perfect for water sports and use in bad weather.
Detergent type solution used after the film has had its final wash to lower the surface tension of water and prevent drying marks.
Artificial light appears in a variety of forms - tungsten and fluorescent being two of the most widely used. Each type of lighting produces a different colour temperature that our brain compensates for to make everything appear as though it's neutral light. Digital cameras and film are not so forgiving and record the colour as it really is, so in tungsten light the picture comes out orange/yellow and fluorescent goes green. These colour casts can be corrected using filters on a film based camera, and digital cameras have a white balance setting to make the pictures look like the view our eyes see. Some models have manual white balance control where you select the type of lighting from a list, but most take care of the colour automatically.
A light source that contains a mixture of all wavelengths of the visible spectrum.
A lens with a short focal length used to capture a wider angle of view.
