The art and science of producing permanent images of objects on light-sensitive surfaces is known as photography.
The art and science of producing permanent images of objects on light-sensitive surfaces is called photography. It involves capturing light or other electromagnetic radiation on a photosensitive medium, such as film or a digital sensor, to create a visual representation of the subject.
Photography can be broken down into several key steps:
1. Light Capture: Light from the subject enters the camera through a lens. The lens focuses the light onto a light-sensitive medium, which can be traditional film or a digital sensor.
2. Exposure: During the exposure, the camera's shutter opens to allow light to reach the photosensitive medium. The duration of exposure determines the amount of light that enters and affects the final image.
3. Image Formation: The light-sensitive medium, whether film or digital sensor, reacts to the light and records the image. In film photography, this reaction occurs due to the photosensitive chemicals on the film surface. In digital photography, the digital sensor converts the light into electrical signals that are processed to create a digital image.
4. Processing: In film photography, the image on the film is developed using chemicals to make it visible. In digital photography, the captured image data is processed within the camera or in post-production to enhance colors, contrast, and other aspects of the image.
5. Output: The final step involves the conversion of the image into a visible form. This can be done by printing the photograph on paper, displaying it electronically on a screen, or sharing it digitally on the internet.
Overall, photography combines technical knowledge and artistic skills to create visually appealing and meaningful images. It requires an understanding of light, composition, camera settings, and post-processing techniques.
