I notice that I didn't update anything on this blog for nearly 1 year. Wohohoho, that long. The last post was about our angka..sawan. Dr SMS landed back to earth already but no update on my photo blog. There are lots of thing happening surround me but I've been busy lah.
I got Streamyx (that's Malaysian Broadband ISP) connection at home now, but I'm starting to wonder if I had time to fully utilize it. Aihhh so little time spend for myself
Back to my so called photography hobby topic, what's new aah. Well I meet a new photography buddy, Mr Shazman, which happend to be my current boss. Syiok aaa ada budy, we can share knowledge on photography anytime. We've been experimenting alot especially on lighting. Shazman bought a Digicolor V-300x studio flash set for about RM1500.
Since then I can pinjam his light for experimenting purposes. He also ask me lot of question and somtimes I can't answer him straight away because I forgot some photography terms.
So below you can find all the term involve in photography. If you still can't understand, open up your browser and go to Google laa buddy. Lots of answer you can find there.
Accessory shoe/Hot shoe. Bracket to hold a flashgun on top of a camera. Most are hot shoes with contacts to fire the flash. Modern cameras may have several contacts for auto-zoom and auto exposure functions of the flash. (Note this is the worst place for a flashgun for lighting!).

Standard zoom. Commonly used to describe a zoom lens which covers the area of 28mm to 85mm focal lengths in 35mm photography.
Starburst filter. Starburst filters are etched to break up a point light source into a number of rays.
Stereo photography. Needs a camera with two lenses mounted next to each other. Resulting prints are viewed with a stereo viewer.
Still video. Uses two inch floppy disk or computer chip to store and electronic image.
Stop. In photography a colloquial used in reference with exposure. Opening up a shot means means you double the exposure; closing down a stop means halving the exposure.
Stop bath. Bath between developer and fixer. Stops development instantly.
Stop-down. Adjusts the lens aperture down, ie to a higher number and thus reducing the amount of light exiting the lens.
Stop-down metering. Metering technique which means the lens is stopped down to the required aperture. Not common nowadays. See Open aperture metering.
Strobe. Flash Americanism for flash. Here, it means flash which fires several times to record multiple images on film.
Studio flash. Mains flash designed for studio use. See Mono-blocs.
Subtractive printing. Colour printing technique using combinations of cyan, magenta and yellow light.
Superzoom. General term for 35mm format lenses with a focal length range of 28mm to 200mm or 80. SVC Still video camera.
Sync cable. Cable to link flash to camera.
T2 mounts. A lens mount system used to attach accessories such as slide copiers to cameras. Also used for some mirror lenses. Has no camera to lens linkage so operations such as aperture control are manual.
Teleconverter. A teleconverter is an optical accessory increases the local length of lens it’s attached to. The most common types are 1 .4x and 2x converters. A 1.4x will turn a 200mm Lens Into a 280mm and a 2x turns it into a 400mm.
Test strip. A strip of printing paper exposed in steps of Increasing time to assess the required exposure and filtration for your negative or slide.
Through-the-lens metering.Commonly known as TTL metering. A lightmeter is built into the camera body and takes the reading from the light passing through the lens.
Through the-lens viewing. What the lens fitted to your camera sees via a reflex mirror.
Thyristor. Power saving circuitry found in most auto flashguns.
Time exposures (T). A shutter speed similar to B. With ‘T’ first depression of the release opens the shutter. The second press shuts It.
Time lapse. A technique used to record a sequence of events over a period by taking pictures at regular. intervals. Some cameras have a built-In interval timer (called intervalometer).
Tonality. Relates to the strength of greys, whites and blacks in the print.
Toner A chemical solution used to change the colour of a print through bleaching and redevelopment.
Tone separation. A process sometimes referred to as posterisation.
Transformer. Two forms are available ~ either step up or step down. Some are stabilised for constant current flow.
Tricolour. A form of additive colour printing using three primary colours.
Tripod. A three-legged device for holding a camera steady.
Two-touch zoom. See Zoom types.
Tungsten balanced. A type of film balanced to record tungsten light as if It where natural light.
Tungsten lights. Several forms are available: photofloods, photopeals , tungsten halogen.
Umbrella. Used for bouncing light back from a flashgun. Available in white, silver or gold.
Universal developer. Developer for processing negatives and prints.
Upratlng. Underexpose a film and then over develop 10% compensate. See Push processing.
Vacuum pressure plate. Unique to the Contax RTS III. A system designed for the ultimate in film flatness.
Vanishing point. Point in perspective where receding lines appear to join. Distant railway lines, shot on a wide- angle show this effect.
Variable-contrast paper. Printing paper that features different grades which are accessed by coloured filters. Magenta filters give harder grades while yellow filters give softer grades. Combined the filters can maintain the exposure at different grades.
Vari-colour filters. Used in conjunction with a polarising filter. By rotating the polariser the colour of the image, created by the vari-colour filter, changes from one colour to another.
Viewing filter. Special filter that allows you to study the tonal relationships of a scene before making an exposure.
Vignetting. Technique to fade out towards the edges of a photograph. Soften the edges by using a soft spot filter. Alternatively hold back or burn in light from the edges of a photo, when printing. creates a white or black vignette. See Cut-off.
Voltage stabilisers Used in the enlarger’s mains transformer to stop fluctuation in electrical power,
Waist-level finder. Folding hood supplied as standard to many medium format cameras.
Wam-toned paper. Paper with silver chloride as well as silver bromide in emulsion to produce a warm tone. Agfa Record-Rapid is a popular example.
Water filter. Device that filters out grit and other nasties.
Wetting agent. Chemical used to reduce the surface tension of water. Added to the final wash, when processing films to improve draining and prevent drying marks.
Window mount. Bevelled aperture cut out of card. The card is then placed over a photograph.
X-rays. Invisible electromagnetic radiation beyond ultra violet on the spectrum.
Zone System. Made popular by Ansel Adams, it’s a method of visualising a scene in various shades of grey when shooting black & white and using the information to meter precisely. Used in conjunction with controlled development for accurate representation of the scene.
Zooming Effect. created by altering focal length of a zoom lens during a long exposure.
Zoom compact. Compact with a motorised zoom lens built-In. See Camera types.
Zoom slide copier. Simple accessory used to copy slides.
Zoom flashhead. Flashgun with adjustable head. Alters angle of beam to provide same coverage as the camera lens used.
Zoom lens. A lens with adjustable focal lengths within a set range.
Zoom type. Two types are available, one-touch and two-touch. One-touch lenses can be focused and zoomed using a single barrel twist to focus and push-pull to zoom. Two-touch lenses have separate rings to focus and to zoom, making them slower in operation but more precise.
Enough ka? I think I stop here la OK? Vrooom
JIJOI is my nickname during my childhood. But when I entered university, no one call me by that name anymore. Then Shazman suddenly called me that during our journey to MDeC mimicking a radio ads, "Dapatkan produk terbaru dari Jijoi JPEG". Sound catchy & funny at the same time.
You guys got nothing better to do ehhh.
