The Glasgow Gallery of Photography is running a month long exhibition in July called Environment. The theme of Environment for this exhibition is quite a wide covering theme, so if you have images that explore the different environmental impacts that the world is currently going through, this exhibition is for you. But it also covers the environment that surrounds us in our day to day lives, so if you have Street or Urban photography, this exhibition is for you. It is also for you if you have Landscape or Seascape images you want to share, or even Architecture or Nature. Environment covers a lot of areas of Photography, so whether you live in the city or the country side, take some interesting photographs of your environment and submit to this exhibition.

Story is an open call for photographers to submit up to 8 images that tells a story within a single image.

Shutter Speed is probably the easiest one to understand. As the name suggests shutter speed is a measurement of how long the camera’s shutter stays open for when you take a photo. A longer shutter speed lets more light in, a faster shutter speed lets in less. But, shutter speed also affects how much movement your camera captures. The longer the shutter is open the more movement it will capture. So, if you want to capture movement (which will appear as blur) use a longer shutter speed. If you want to freeze movement (for example if you’re capturing someone running and want a crisp image of them, with no blur), use a faster shutter speed. Shutter speed is measured in seconds and fractions of seconds. So a shutter speed of 1 second would be much slower than one of 1/500 of a second. Here are a couple of photos of my daughter on a slide that illustrate the difference shutter speed makes. The first photo was taken at a shutter speed of 1/100 – you can see that it’s blurry, as the shutter speed was too slow to ‘freeze’ her movement on the slide. The second photo was taken at 1/500 which is faster, and here you can see that the movement has been ‘frozen’ giving a crisp image.
