Short for ‘in-body image stabilisation’ and a term used by Fujifilm for its X-H1 pro mirrorless camera. In-body image stabilisers shift the camera sensor to counteract any camera movement during the exposure. It’s the first time Fujifilm has used in-body stabilisation, but it’s already used by Pentax, Panasonic, Sony and Olympus.
All lenses produce a circular image on the camera sensor or film, and this ‘image circle’ must be at least large enough to cover the full film/sensor area. Different lenses designed for different sensor sizes and formats have different-sized image circles. Lenses designed for APS-C format cameras, for example, have a smaller image circle than […]
Any program which can edit, enhance or manipulate digital images is technically an image editor, though usually this term is reserved for more advanced, technical programs like Photoshop rather than simpler everyday photo management tools like Apple Photos or Google Photos.
Many cameras offer extended (expanded) ISO settings beyond the standard range. These can help you out in an emergency but they’re not designed for everyday use because the image quality is significantly reduced. Some cameras also offer expanded low settings such as ISO 50.
This setting increases the camera sensor’s sensitivity to light. Each ISO step doubles the sensitivity, so it’s easy to use ISO as another exposure control alongside shutter speed and lens aperture. The more you increase the ISO, though, the more the image quality degrades. Photo by ShareGrid on Unsplash
The iPhone comes in two sizes – standard and ‘Plus’ – and the iPhone 7 Plus has two cameras, one with a regular 28mm equivalent wideangle lens and the other with a 56mm equivalent lens. It uses both in combination with ‘computational imaging’ to offer a continuous zoom feature and a ‘portrait’ mode which adds […]
Apple’s digital tablet, which comes in different sizes and memory configurations. The smallest and lightest is the iPad Mini, while the largest and most powerful is the iPad Pro.
The name of the operating system for iPhones and iPads. It’s often used to distinguish apps for these devices from those for Android devices. Most apps are available in both iOS and Android versions.
A camera setting or remote controller which fires the camera’s shutter at set intervals, stopping when it’s taken a specified number of images. The pictures can then be used to analyse movement or change over time or, more likely, combined to make a time lapse movie.
Sometimes called an ‘intervalometer’, this is a feature on more advanced cameras that takes picture at fixed intervals automatically. It’s most often used for time lapse photography. You set the interval between pictures and the number of shots you want the camera to take.
Using mathematical analysis to fill in the gaps in data. The photosites on sensors only capture red, green or blue light, so interpolation is used to examine surrounding pixels and calculate full colour values from those. When you increase the size (in pixels) of a photo, the software interpolates new pixels from the existing ones.
Mac-only application which increases global and localised contrast effects to give images extra drama and ‘punch’. It works either as a standalone application or as a plug-in, and as usual with MacPhun software you can use one of many different presets or use your own manual settings.
This is a fully automatic mode on Panasonic digital cameras which analyses the scene in front of the camera and automatically selects an appropriate scene mode – normally you have to choose them manually – here, the camera is doing it for you, hence ‘intelligent auto’.
An automatic object removal tool in Serif Affinity Photo. You brush over the object or blemish that you want to remove and the Inpainting Brush automatically fills in the area with pixels and patterns from surrounding regions. It’s quick and often very effective and comparable to Adobe’s ‘content aware’ retouching tools.
A branch of photography that uses parts of the light spectrum not normally visible to the naked eye but which can still be captured on film or digitally using black and white or colour film made sensitive to infra red or a digital camera modified to remove the infra red filter that normally covers the […]
With some programs you can’t just open an image straight away, you have to import it into the software’s catalog first. This is how database-driven cataloguing programs like Lightroom, Capture One and Aperture work.
A mechanism that counteracts camera movement during the exposure. Lens-based stabilisers use a moving lens element, while sensor-based stabilisers move the sensor itself. Image stabilisers are used to get sharper telephoto shots and low-light shots without camera shake.
Digital cameras offer a choice of image sizes. Normally, you’d choose ‘Large’, which gives you the maximum resolution offered by the sensor. But most cameras also offer ‘Medium’ settings (around half the pixels) and ‘Small’ (around a quarter the pixels).
As well as saving JPEG photos at different sizes, cameras also offer different quality settings like ‘Fine’, ‘Normal’ and ‘Basic’. Fine produces the best picture quality and is the one to go for if you can. If your camera shoots RAW files, this is where you’ll find the RAW option.
