3. ISO Sensitivity: ISO sensitivity determines the camera sensor’s level of light sensitivity. In long exposure photography, you’ll typically use a low ISO setting to minimize digital noise and maintain image quality. However, in low light conditions, you may need to increase the ISO to achieve proper exposure without compromising image sharpness.
4. Composition: Composition plays a crucial role in long exposure photography, just like in any other genre. Pay attention to elements such as leading lines, symmetry, patterns, and the rule of thirds to create visually engaging images. Experiment with different compositions to add interest and depth to your long exposure shots.
5. Movement and Motion Blur: Long exposure photography allows you to capture the passage of time and movement in a single frame. Experiment with different shutter speeds to achieve varying degrees of motion blur, whether you’re capturing flowing water, moving clouds, or light trails from vehicles or stars.
6. Exposure Control: Achieving the correct exposure is essential in long exposure photography. Use the camera’s light metering system to assess the scene’s brightness and adjust the exposure settings accordingly. Bracketing exposures can help ensure you capture the perfect shot, especially in challenging lighting conditions.

By mastering these basic principles of long exposure photography, you’ll be better equipped to create stunning images that showcase the beauty of time and motion.
