Bracketing is when you take the same shot multiple times at different exposure settings. The aim with this is to capture different scales of light and colour within one specific setting where taking one single image would not capture all of that. The darker shot saves highlight information like bright skies or windows to the outdoors and the lighter shot saves shadow information. Later you can then take the correctly exposed image, with the under & overexposed ones of the same setting and stack them together combining the best parts of each exposure into one image where both highlights and shadows look balanced in each area. This then becomes a HDR image, useful for shooting both interior & exterior lighting in the same image and also capturing a wider scale of colours and detail within the image.
For this shoot I found both an outside location with a variety of colours, textures, and patterns, and indoor one. Using the light meter on the camera, I started with shooting a perfectly exposed image with the light meter on 0, I then shot an image over exposed by 2 steps and then underexposed by 2 steps. To do this I kept the aperture and ISO the same and changed the shutter speed to allow more/less light in crating that over/underexposed finish. One part I found difficult was ensuring there was no movement of the camera and no camera shake. Despite using a tripod, to get a very overexposed image I had to use a slow shutter speed of 1/5 and 1/13. This meant that the shutter was open for a considerable amount of time and was more sensitive to any camera movement. If I were to do this again, I would experiment with more locations and include more interesting aspects in the chosen locations such as more colour and better compositions.
