The document provides an overview of the fundamentals of digital photography, emphasizing the three key aspects: aperture, shutter speed, and ISO. It explains how these elements control exposure and affect the sharpness and motion capture in images. Additionally, the guide covers the importance of white balance for accurate color representation in photographs.
Digital Photography Fundamentals
- 3. The art or process of producing Images on Photosensitive Surfaces (Camera Rolls, Sensors) using light.
- 4. Three fundamental aspects of Photography •Aperture •Shutter Speed •ISO
- 5. Aperture • Opening in the lens or diameter of the Lens. • Controls the amount of light falling on the Camera Sensor • Larger the diameter, more the amount of light • Smaller the diameter, less the amount of light • It is expressed as F Stop on the camera or the lens. • Controls the depth of field (DoF)
- 6. • Smaller the f number larger the opening • Larger the f number smaller the opening F- Stops
- 7. Depth of Field (DoF) Acronym for Depth of Field is DoF DoF is defined as the Portion of Image which is in Sharp Focus DoF is dependent to a large extent on the F number selected on the Came Smaller the F number Shallower the Depth of Field(DoF) Larger the F number higher the Depth of Field(DoF)
- 8. F 2.8 F 10 F 32 F 2.8 F 9 F 32
- 9. Shallow Depth of Field(DoF)
- 10. Shallow Depth of Field(DoF) Aperture of F 5.6
- 11. Shallow Depth of Field (DoF)
- 12. Shallow Depth of Field (DoF) Aperture of F 4
- 13. Shallow or Larger DoF ??
- 14. Shallow or Larger DoF ?? Aperture of F 10
- 15. Shutter Speed The Amount of time the Shutter of your camera is open. Measured in fractions of Second e.g. 1/30 Sec, 1/100 Sec, 1/250 Sec, 1/1000 Sec. In some cases measured in Seconds too e.g. 1 Sec , 2 Sec, 30 Seconds or more Slower Shutter speed (e.g. 1 Sec, 2 Sec) causes blur. Faster Shutter Speed e.g. 1/250 Sec, 1/500 Sec, 1/1000 Sec freezes Motion Use Fast Shutter Speed for fast moving subject. Can use Slow shutter speed for static subjects or when light is low
- 17. Slow Shutter Speeds Shutter Speed: 2hrs and 30 Mins!!!!
- 19. Slow Shutter Speeds Shutter Speed: 30 Seconds!!
- 21. Fast Shutter Speeds Shutter Speed: 1/800 Sec
- 23. Fast Shutter Speeds Shutter Speed:1/1250 Sec
- 24. ISO Defined as the Sensitivity of your Camera Sensor to Light Higher the ISO number, more the sensitivity of the Sensor Recommended to use the lowest ISO your camera can offer Increase the ISO , when there is no sufficient light Generally increases as 100, 200 , 400, 800, 1600 and so on Higher ISO will result in noise in the Images Image quality degrades Avoid Shooting at high ISO unless absolutely necessary
- 25. ISO 100
- 26. ISO 6400
- 27. ISO 12800
- 28. White Balance White Balance is the process of removing Unrealistic colour casts from Images, so that the object appears as the same colour in your Image, as you saw it in person. Setting the correct white Balance will help us get the colours in our images as accurate as possible
- 29. White Balance Settings Auto – Camera decides on the colour temperature. Works best for most situations. Tungsten- Used normally when shooting under Incandescent lighting. Fluorescent- Used when shooting under Fluorescent light. Daylight/Sunny- Normally used when shooting under the Sun. Cloudy- Warms up the colour Shade- Light in Shade is normally cooler, so this mode warms up the colour a bit more
- 34. Understanding Exposure Exposure determines how light or dark an Image will appear, once it has been captured by your camera. It’s dependent on three factors Aperture, Shutter Speed and ISO These three factors are interrelated and critical to get correct exposure for an Image
