The document discusses various photography techniques and terms including shallow and deep depth of field, fast and slow shutter speeds, film grain, and digital noise. Shallow depth of field focuses on a subject while blurring the background, while deep depth of field keeps more of the scene in focus. Fast shutter speeds freeze motion but provide less detail, while slow shutter speeds can capture motion but with blur. Film grain and digital noise refer to the texture and speckles that can degrade image quality in film and digital photos respectively.

- 1. PHOTOGRAPHY TECHNIQUES Elizabeth Rawding AND TERMS
- 2. SHALLOW DEPTH OF FIELD Depth of field is the distance between the nearest and farthest objects in a photo that will seem acceptably sharp in an image.
- 3. DEEP DEPTH OF FIELD You can use deep depth of field to make one object stand out from a large group of similar objects. Much like shallow DOF
- 4. FAST SHUTTER SPEED In photography shutter speed is used to help the exposure time. The faster you put the shutter speed on the more pictures will come out and much fewer details in the object moving.
- 5. SLOW SHUTTER SPEED Is much like fast shutter speed, but when you set the shutter speed slower you tend to get a somewhat moving picture. This is because as you take the picture objects around you may be moving.
- 6. FILM GRAIN Film grain or granularity is the random optical texture of processed film due to the presence of the tiny particles of metallic silver, or dye clouds, developed from silver halide.
- 7. DIGITAL NOISE "Image noise" is the film grain for cameras. For digital images, this noise appears as random speckles on an otherwise smooth surface and can significantly degrade image quality.
