What is the difference between analogue and digital?
Analogue and digital formats are, broadly speaking, both ways of storing information, but the information is contained in very different ways. In analogue technology, waves or signals are stored in their original form (such as vinyl where grooves are etched in order to create sound waves on the disk itself.)
However, in digital technology, waves or signals are converted into numbers and stored as code on a digital device such as a hard drive, memory card or computer. Examples of analogue formats include vinyl, cassettes, and of course film photos. Unlike digital formats they do not need to be translated from code by a computer in order to be understood.
Let’s take a closer look specifically at the differences in analogue and digital photography:
Film photography captures images by exposing individual frames on a roll of film to light. Film is made of plastic layers containing silver halide crystals that darken when exposed to light, capturing negatives of images. Film can be developed in a darkroom and using liquid chemicals to create the final print of the photo. This print is a piece of analogue media that can be touched and held in the hands.
Digital photography mimics the process of using light to capture images. But it uses an electronic sensor, rather than film. Digital photographs are stored on our devices, and their resolution is measured in megapixels. Each pixel is converted into a string of 1s and 0s that requires a computer to read them and present them to us as something we recognise as a photograph.
We encourage using analogue, for the character, the film grain, tangible quality and emotions it gives you!

From a SLR, to TLR, to rangefinder or point & shoot cameras – find out how these different types of cameras operate.
The Sunny 16 Rule is a way to meter for correct exposure during daylight without using the camera’s meter. It is great for photographers who don’t want to get slowed down by metering for every shot or rely too much on their camera’s in-built light meter.
Put simply, an overexposed image is one that is brighter than the reality of the scene you’re trying to photograph, while an underexposed image is darker than reality. Overexposure generally means you are giving your film too much light, and with underexposure you have the opposite problem of not enough light.
There’s no need to load film in the dark but going under the shade or subdued lighting are ideal conditions when loading film.
Full-frame film cameras create an image across the entire 36 mm by 24 mm frame. Whereas half-frame cameras can fit two images onto one frame and each image measures 18 mm by 24 mm.
A standard roll of 35 mm film allows you to take 36 photos. However certain film stocks only allow 24 photos to be taken. The number of exposures is indicated on the outside of the box of film.
Coming from the Japanese word “boke-aji” which means the quality of blur, bokeh describes the quality of a photo’s “blurry“ and out-of-focus portion.
Metering is the process of reading the lighting conditions before taking a photograph, to make sure you will get the right exposure for your images. This is where shutter speed, aperture, and ISO all come into play.
