What is Photographic Paper?
Photographic paper for chemical printing is very similar to film, and totally dissimilar to photographic paper for inkjet printers. Paper for chemical printing is coated in a light-sensitive emulsion of silver halides, which convert to metallic silver when exposed to light. As with film, these tiny silver particles collect in clusters and appear black; thus forming the tonal range of your image. One side of the paper is slightly shinier than the other side; the shine is created by a layer of emulsion and this side of the paper will capture your image.
There is an enormous range of photographic paper on the market. Few of them below:
- Resin-coated paper (RC)
- Fibre-based paper (FB)
- Graded paper
- Multi-graded paper
What is Twin Lens Reflex (TLR)?
The Twin Lens Reflex (TLR) camera attempted to overcome limitations in the early SLR camera. With one lens and mirror (long before the introduction of the instant return mirror), the SLR camera blacked out as the picture was taken until the mirror was reset. Shown in cross-section, the TLR camera has two lenses and one mirror. The lower taking lens has a shutter and images through a darkened chamber on to the loaded film. Above, a second lens is backed by a fixed mirror, angled at 45°, letting the photographer look down on to a ground-glass viewfinder to focus and compose. The image is upright but left- to-right reversed. The advantage of the TLR is that the viewing lens does not black out when the picture is taken.
A classic Mamiya TLR roll-film camera,which offered interchangeable lens pairs unlike the more famous fixed lens Rollei TLRs.These cameras were popular with fashion and portrait photographers as they gave continuous sight of the subject.However,with separate viewing and taking lenses they suffer from parallax problems with close subjects.
What is Pinhole Photography?
Pinhole photography uses a pinhole instead of an image-forming lens capable of being focused. A tiny hole produces an image by restricting possible light paths from brightly lit points on the subject to just one. A coherent, upside-down image can be projected inside a camera by a pinhole and there is no concept of focusing; the further away the pinhole is from the film or sensor, the bigger and dimmer the image. The pinhole image is effectively made up of tiny overlapping circles. The images projected by pinholes are much dimmer than those focused by lenses and so pinhole cameras require much longer exposure times.
What is Photo-Journalism?
Photo-journalism is the act of gathering, evaluating and disseminating facts of current interest via photographic and literary media. A photo-journalist (or press photographer), while working in a similar style to that of a documentary photographer, may convey a particular point of view through an acute understanding of the power of a certain camera angle, point of interest, or cropping technique in order to produce a shot that will intensify the drama of the moment.
A successful photo-journalist will grab the attention of the viewer through his or her ability to express the drama of an event or extract the meaning of a situation within a single photograph. It’s a very tough and competitive job as you may be on call 24 hours a day, in all kinds of conditions, waiting for your moment, covering the action, or preparing to capture the shot.
What is Lens Extension Tubes?
The easiest way to increase image magnification in close-up or macro photography is to move the lens further away from the image plane. This is done by placing rings or tubes – often supplied in sets – between the camera body and lens. If the tube length is the same as the focal length, then the reproduction will be life-size.
