The first stage of making a darkroom print is to determine the exposure time. If you have already created a contact sheet of your negatives, and they appear correctly exposed, then you should have a rough idea of the necessary exposure (provided you haven’t moved the enlarger head or aperture setting after exposing the contact sheet). Note: If you change the degree of enlargement you will also need to adjust the exposure. Some enlargers have scales printed on their columns to make this easier. Another...

What are film developers? Film developers are a photographic chemical that turns your exposed film into working negatives as part of a processing workflow. (You will also need a stop bath and fixer - for more information on how to process your film or which chemistry to choose read our guides). We offer a broad range of film developers that are designed to exploit the different characteristics of our films. Developers are available in either powder and liquid concentrate form and have a range of charact...

Although many film cameras have inbuilt light metering systems, a light meter instrument can also be used. Light Meters can measure the amount of light falling on a subject (incident light), or being reflected by a subject (reflective light). By converting these measurements, it defines what would be the most beneficial shutter speed and f/stop to use for that given subject. Light Meters are particularly helpful where subject matter / lighting conditions are difficult. Some light meters are also able to...

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...

Contact sheets are a great way to review and record your images. They allow you to view all the negatives on a roll of film before deciding which ones you want to print and how you may want to crop them. They also provide a permanent record of those negatives for filing purposes. How to make a contact sheet To make a contact sheet we recommend using ILFORD MULTIGRADE RC DELUXE Set the enlarger head to a height that gives a 40cm (16in) wide rectangle of light on the baseboard Put a MULTIGRADE fil...

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...

A black border often enhances a print and does not involve any sort of mounting or overlay. Ink or tape borders The easiest way to produce narrow black borders is to rule them with a pen directly onto your finished print: an India-ink pen gives the most solid line, but most permanent (all surface) spirit based markers are much less expensive and will do the job. For slightly wider black borders, narrow, self-adhesive strips are available from graphic arts suppliers. Supplied in dispensers, of various w...

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...
