The Glasgow Gallery of Photography is running a month long exhibition in September called Nature. For this exhibition we are asking photographers to submit images that show the varying aspects of Nature. From the beauty of it, the cruelty of it or maybe the power of Nature. It could be the beauty you see when go outside or how the forces of Nature has impacted where you live and your day to day life. There are so many ways that photography can explore these and many more aspects of Nature, and we want to showcase them in this exhibition.

Nature is an open call for photographers to submit up to 8 images that meet the theme Nature. 

Exhibition Date: 5 – 30 Sept 2023

Submit up to 8 images of any genre of photography, as long as it showcases the theme. Online submission of digital images via the website.

Image requirements: JPEG format; 300ppi and 3000 Pixels minimum on the shortest side.

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.
