Having shot a roll of black and white film it now needs to be processed to create the negatives. At this point your film is still light sensitive so should not be exposed to light. Processing your own film can be highly satisfying and cost effective. It is also easy to learn. The most common method for hand processing film is undertaken by using a Daylight Processing Tank. This piece of kit needs the film to be loaded on to a ‘spiral’ or ‘reel’, in the dark, and then enclosed in a light tight co...

When photographic material is exposed to light it begins to darken. The more light the material receives, the darker it becomes. This opens up a range of possibilities for making fun, creative and artistic images without a camera. Making a picture without a camera couldn’t be easier and is a fun activity to try with children. However, for many, exploring and experimenting with different effects of light on photographic /blog/the-luminogram-process/materials can become an art form by itself. Where to sta...

Silver halide has been used in photographic film and paper for over 150 years and remains a vital ingredient found in all high-quality products. Silver halide crystals in gelatin form part of an emulsion which is used to coat the paper or film. On exposure to light (i.e. in a camera or darkroom), the crystals react turning into silver and forming the image. Silver halide prints There are many ways to produce black & white prints with options varying in quality. Traditional black & white silver ha...

Filters have long been a popular accessory for photographers and offer a number of different functions or effects. In both analogue and digital photography it is possible to recreate some of these in the darkroom or digital darkroom. However there has always been a benefit to getting it right in camera. In black & white photography, colour filters in particular are useful as they can control how the colours in a scene are reproduced as greys. Normal black & white films are sensitive to all wavele...

Retouching is normally done to remove blemishes from the negative or the final print. It can also be used to change the tone or remove unwanted detail.  As retouching can be difficult, care is required. Advice for retouching The most risky retouching techniques involve removing parts of the image, by bleaching, cutting, or scraping with the edge of a sharp knife. The addition of density is generally less risky, and can be done using dye, paint etc, or a suitable soft pencil. When retouching prints from o...

Mounting your Prints Even the most stunning print can look better when it has been properly mounted. Mounted prints are also better protected as they are kept flat with the image separated from the immediate surroundings by unobtrusive margins. There are no hard and fast rules about mounting prints; the most suitable results will depend on individual preference, the nature of the image, the intended use and other circumstances. It is recommended that only boards and other materials intended for the p...

Testing your Safelights Safelights are an essential component in any darkroom set up. We recommend testing them annually, as ageing can change the transmission characteristics of the filters. This can cause visible fogging of the print or, more likely, a subtle but noticeable drop in contrast. When setting up your safelights always read the instructions and don't exceed the recommended bulb wattage. Fitting a brighter bulb or mounting your safelight too close to your developing dishes,  may cause degra...

Split grade printing The version of split grade printing described here is that taught to me by the ILFORD head printers, Mike Walden and Terry Offord, and is the simplest, fastest way to make good darkroom prints from pretty much any negative. (The exception is really underexposed negatives to print these you usually only need high contrast). This is a very powerful technique that can be used routinely with variable contrast (VC) papers, such as ILFORD MULTIGRADE. It makes use of the differing performa...
