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...

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...

What is the luminogram process? The Luminogram process is light, directed onto photo paper in the darkroom. About as basic as ‘photography’ can get. It has been with us for a long while. László Moholy-Nagy (1895-1946) started using it in 1922, while Gottfried Jäger described it as "the result of pure light design; the rudimentary expression of an interaction of light and photosensitive material… a kind of self-representation of light." And yet it has always seemed to sit on the sideline...

1992 - How I met Masterji Soon after leaving my staff photographer’s position on the local newspaper where I’d been employed for the previous 5 years and with the luxury of in-house film processing no longer a convenient option I began using my local city centre professional colour lab, in Coventry. During the accumulating hours I spent in that lab waiting for my 35mm films to process, watching small colour prints dropping from the conveyor belt from the end of the machine, I very watched a short In...

I always loved celluloid pictures. Maybe I was drawn in as a baby, while the 8mm camera whirred (and the handheld light blinded). Maybe it was being so thankful to my big brother for lending me a 35mm rangefinder and showing me how to use it at age 10. Might have been the Minolta-16 he gave me (as a graduation present?). What a sweet little 16 that is, and I’ve still got it. Can you get those cartridges now? I envied his Pentax Spotmatic as I shot 8mm motion pictures on the point and shoot family camera,...

 A lifelong hobby One of my lifelong hobbies is photography. I have been taking photographs since I was about 10 years old when I was given an old Kodak folding pocket camera that had belonged to an uncle, Bertrand Perrett, who was a professional photographer and painter in England. I learned to develop and print black-and-white film at school when I was a teenager back in the 1970s. The Slower Pace When digital photography came along I moved to that medium, but recently I’ve come back to film aga...
