You will likely hear the following terms regularly mentioned in meetings and in club literature:
Clubs & Organisations
The Yorkshire Photographic Union. An organisation representing camera clubs across the Yorkshire region. We take part in their annual competition.
The Photographic Alliance of Great Britain is a membership organisation that co-ordinates, activities for photographic Clubs in England, Scotland, Wales & Northern Ireland.
A competition held between 10 clubs in West Yorkshire, comprising of four rounds where each club enters five images. Participating clubs take it in turn to host the competition. Of the five images entered by each club, one of the images must fit a rotating theme and another must fit a subject specified by the host club. There is no restriction on the remaining three images.
Projected Digital Image. An image captured with a digital camera (or scanned from film) and projected.
A file created by a digital camera that contains all the exposure information recorded by the camera at the time of capture. RAW images are akin to a negative and require processing to be “developed” into the end result. Many photographers favour shooting RAW images instead of JPEGs as they offer far greater scope for correction and manipulation.
The standard image file format used for sharing and storing photographs. All digital cameras can take images in this format. JPEG is a “lossy” format that uses compression that throws away some of the image data to make the file size smaller. JPEG files tend not to be very good for editing and offer limited scope for fixing exposure, recovering highlights and shadows etc.
Dots Per Inch. This measure is usually only important when printing. Choosing an appropriate DPI is important to make sure your picture looks sharp and crisp at normal viewing distances. Usually 200-300 DPI is fine for a competition print at around 16×12 inches. For example if your photo is 4000 x 3000 pixels (12 megapixels) you can print it at 16 x 12 inches at a resolution of 250 DPI (4000 / 16 = 250).
Digital cameras can capture only a subset of all the natural colours that the human eye can perceive and most computer monitors (especially on laptops) can display even fewer. When we talk about the colours a digital photo contains we refer to its “colour space”. Some colour spaces retain more of that information and some less. The sRGB standard is the lowest common denominator and is supported by nearly all cameras and computers by default. A good quality computer monitor will generally be able to display around 90 to 100% of the sRGB colour space. High end monitors aimed at professional photographers and designers can display significantly more, for example covering the AdobeRGB colour space as well as sRGB, but relatively few people have access to them. Images submitted to club and external competitions should be in the sRGB colour space.
Audio Visual. We use this term to refer to recorded sequences that contain some combination of photos and videos set to music and/or narration. Every year we hold an AV competition where we ask members to produce these sequences as a way to explore story telling. AVs are typically now recorded as video files but in the past people would create self playing slideshows with software like PicturesToExe.
Popular Software Packages
The industry standard photo editing tool used by amateurs and professionals alike. Allows complex retouching and modification of images.
The most popular photo cataloging and editing software. Doesn’t allow as much manipulation as Photoshop but makes many common edits far simpler to achieve.
A tool for creating audio visual slideshows that’s popular with some members.
