Use Filters. Graduated neutral density (AKA ND grad) and polarizing filters are purely as useful in monochrome photography as they are in colour. In fact, because they manipulate image contrast they are arguably more useful . An ND grad is helpful when you require to retain detail in a bright sky while a polarizing filter should be used to reduce reflections and boost contrast. Alternatively, see taking two or more shots with diverse exposures to create a high dynamic range (HDR) composite. Don’t be afraid to use a ND grad with a standard neural density filter if the sky is brighter than the foreground in a long exposure shot. Coloured filters, which are an essential tool for monochrome film photographers, should also be useful for manipulating contrast in digital images. They work by darkening objects of his opposite colour while lightening objects of his own. An orange filter, for example, will darken the blue of the sky while a green one will lighten foliage.
Try Long Exposure. Long exposure shots can work really well in monochrome photography, especially where there’s moving water or clouds. During the exposure the highlights of the water, for example, are recorded across a wider place than they would with a short exposure and this should help enhance tonal contrast. The blurring of the movement also adds textural contrast with any solid objects in the frame. If compulsory , use a neutral density filter such as Lee Filters’ Big Stopper or Little Stopper to decrease exposure and extend shutter speed (by 10 and 4 stops respectively). naturally , when exposures extend farther than in respect of 1/60 sec a tripod is wanted to keep the camera still and avoid blurring. It’s also advisable to use a remote release and mirror lock-up to minimise vibration and produce super-sharp images.
Dodge and Burn. Dodging and burning is a thoroughfare that comes from the traditional darkroom and is usually used to burn in or darken highlights and hold back (brighten) shadows. Photoshop’s Dodge and Burn tools allow a level of control that film photographers could only ambition of because you should target the highlights, shadows or mid-tones with both. This means that you could use the Burn tool to darken highlights when they are too bright, or the Dodge tool to perk up them to increase local contrast. It’s a good plan of sharing a sense of superior sharpness and enhancing texture. Plus, because you could set the opacity of the tools, you should build up her effect gradually so the impact is crafty and there are no hard edges.
Shoot RAW + JPEG. The greatest monochrome conversions are found by chance by editing raw files which have the full colour information, but if you shoot raw and JPEG files simultaneously and set the camera to its monochrome photograph Style/Picture Control/Film Simulation mode you get an indication of how the image will look in black and white. As most photographers struggle to visualise a scene in black and white, these monochrome modes are an invaluable tool that will help with composition and scene assessment. numerous cameras are also capable of producing decent in-camera monochrome images these days and it’s worth experimenting with image parameters (usually contrast, sharpness, filter effects and toning) to find a look that you like. Because compact mode cameras and compact cameras show the scene seen by the sensor with camera settings applied, users of these cameras are able to preview the monochrome image in the electronic viewfinder or on rear screen before taking the shot. DSLR users may also do this if they kick in his camera’s live mental picture wont , but the usually slower responses mean that numerous will find it preferable or check the image on the screen post-capture.
Look for Contrast, Shape and Texture. The complimentary and opposing colours that bring a colour image to life are all reduced to black and white or shades of grey in a monochrome image and you have to look for tonal contrast to make a shot stand out. In colour photography, for example, your eye would right away be drawn to a red object on a green background, but in monochrome photography these two areas are likely to have the same brightness, so the image looks flat and dull straight from the camera. happily , it’s possible to work adjust the brightness of these two colours separately to introduce some contrast. However, a good starting point is to look for scenes with tonal contrast. There are always exceptions, but as a general rule look for scenes that contain some forceful blacks and whites. This should be achieved by the light or by the brightness (or tone) of the objects in the scene as well as the exposure settings that you use. The brightness of the bark of a silver birch tree for example, may inject some contrast (and interest) in to a woodland scene. Setting the exposure for these brighter areas also makes the shadows darker, so the highlights stand out even more. Look for shapes, patterns and textures in a scene and move around to find the best composition.
Take Control. Although coloured filters may still be used to manipulate contrast when shooting digital black and white images, it’s more prominent to save this work until the processing stage. Until a some years ago Photoshop’s Channel Mixer was the preferred means of turning colour images monochrome, but now Adobe Camera Raw has more strong tools (in the HSL/Grayscale tab) that allow you to adjust the brightness of eight individual colours that make up the image. It’s possible to adjust one of these colours to make it anything from white to black with the sliding control. However, it’s important to keep an eye on the whole image when adjusting a particular colour as crafty gradations could become unnatural looking. And adjusting the brightness of a red or pink shirt with the red sliding control, for instance , will have an impact on the model’s skin, especially the lips. The Levels and Curves controls may also be used to manipulate tonal range and contrast, but the HSL/Grayscale controls allow you to create demarcation between objects of the same brightness but with unique colours.

Negatives were once commonly made on a thin sheet of glass rather than a plastic film, and some of the earliest negatives were made on paper.

It is incorrect to call an image a negative solely because it is on a transparent material. Transparent prints can be made by printing a negative onto special positive film, as is done to make traditional motion picture film prints for use in theaters. Some films used in cameras are designed to be developed by reversal processing, which produces the final positive, instead of a negative, on the original film. Positives on film or glass are known as transparencies or diapositives, and if mounted in small frames designed for use in a slide projector or magnifying viewer they are commonly called slides.
Many photographic processes create negative images: the chemicals involved react when exposed to light, so that during development they produce deposits of microscopic dark silver particles or colored dyes in proportion to the amount of exposure. However, when a negative image is created from a negative image (just like multiplying two negative numbers in mathematics) a positive image results. This makes most chemical-based photography a two-step process, which uses negative film and ordinary processing. Special films and development processes have been devised so that positive images can be created directly on the film; these are called positive, or slide, or (perhaps confusingly) reversal films and reversal processing.
Film for cameras that use the 35 mm still format is sold as a long strip of emulsion-coated and perforated plastic spooled in a light-tight cassette. Before each exposure, a mechanism inside the camera is used to pull an unexposed area of the strip out of the cassette and into position behind the camera lens. When all exposures have been made the strip is rewound into the cassette. After the film is chemically developed, the strip shows a series of small negative images. It is usually then cut into sections for easier handling. Medium format cameras use 120 film, which yields a strip of negatives 60 mm wide, and large format cameras capture each image on a single sheet of film which may be as large as 20 x 25 cm (8 x 10 inches) or even larger. Each of these photographed images may be referred to as a negative and an entire strip or set of images may be collectively referred to as “the negatives”. They are the master images, from which all positive prints will derive, so they are handled and stored with special care.

Film negatives usually have less contrast, but a wider dynamic range, than the final printed positive images. The contrast typically increases when they are printed onto photographic paper. When negative film images are brought into the digital realm, their contrast may be adjusted at the time of scanning or, more usually, during subsequent post-processing.
A positive image is a normal image. A negative image is a total inversion, in which light areas appear dark and vice versa. A negative color image is additionally color-reversed, with red areas appearing cyan, greens appearing magenta and blues appearing yellow, and vice versa.
In photography, a negative is an image, usually on a strip or sheet of transparent plastic film, in which the lightest areas of the photographed subject appear darkest and the darkest areas appear lightest. This reversed order occurs because the extremely light-sensitive chemicals a camera film must use to capture an image quickly enough for ordinary picture-taking are darkened, rather than bleached, by exposure to light and subsequent photographic processing.
Color positive picture (A) and negative (B), monochrome positive picture (C) and negative (D)
Despite the market’s evolution away from film, there is still a desire and market for products which allow fine art photographers to produce negatives from digital images for their use in alternative processes such as cyanotypes, gum bichromate, platinum prints, and many others.
Negatives are normally used to make positive prints on photographic paper by projecting the negative onto the paper with a photographic enlarger or making a contact print. The paper is also darkened in proportion to its exposure to light, so a second reversal results which restores light and dark to their normal order.
In the case of color negatives, the colors are also reversed into their respective complementary colors. Typical color negatives have an overall dull orange tint due to an automatic color-masking feature that ultimately results in improved color reproduction.
