Definitions
- Referring to the process of engraving a metal plate with a photographic image using sunlight. - Describing the art or practice of producing images using the sun's rays. - Talking about the early photographic process invented by Joseph Nicéphore Niépce in the 1820s.
- Referring to a photographic image created without a camera, by placing objects on photosensitive paper and exposing it to light. - Describing a type of abstract photography that emphasizes shapes, textures, and shadows. - Talking about a technique used in fine art photography to create unique and experimental images.
List of Similarities
- 1Both involve the use of light to create images.
- 2Both are photographic processes.
- 3Both can be used to create unique and artistic images.
- 4Both were invented before the digital age of photography.
What is the difference?
- 1Process: Heliography involves engraving a metal plate with a photographic image using sunlight, while photogram is created by placing objects on photosensitive paper and exposing it to light.
- 2Equipment: Heliography requires a metal plate and specialized equipment, while photogram can be created with photosensitive paper and basic materials.
- 3Style: Heliography produces detailed and realistic images, while photogram emphasizes abstract shapes and textures.
- 4History: Heliography was invented in the 1820s, while photogram was developed in the early 20th century.
- 5Usage: Heliography is less commonly used today, while photogram is still used in fine art photography and experimental techniques.
Remember this!
Heliography and photogram are both photographic processes that use light to create images. However, the difference between the two lies in their process, equipment, style, history, and usage. Heliography involves engraving a metal plate with a photographic image using sunlight, while photogram is created by placing objects on photosensitive paper and exposing it to light. Heliography produces detailed and realistic images, while photogram emphasizes abstract shapes and textures. Heliography was invented in the 1820s, while photogram was developed in the early 20th century. Today, photogram is still used in fine art photography and experimental techniques, while heliography is less commonly used.
