👉 Thru research, also known as through-the-lens or TTL (Through-The-Lens) photography, is a method where photographers use a camera’s built-in metering system to automatically adjust exposure settings based on the scene's light conditions. This process involves the camera measuring the light reflected from the subject and other elements within the frame, allowing it to determine the optimal aperture, shutter speed, and ISO combination for proper exposure. Thru research simplifies the photography process by reducing the need for manual adjustments, making it particularly useful in dynamic or challenging lighting environments. It enhances consistency and efficiency, enabling photographers to focus more on composition and creativity rather than technical settings.
