1. Digital Photography Made Easy With Jim Battles Battles Photography

2. Digital Photography Made Easy …or so we think

3. Disclaimer: Although I use digital photography daily and am the one teaching this class…

4. Disclaimer: …I’m still learning too.

5. Digital vs. film lower costs after startup more efficient workflow no scan/sep costs instant gratification

6. Hardware Camera: professional vs. consumer controls MP rating

7. Hardware Camera: optical or digital zoom media

8. Hardware Computer: Lots of RAM Color calibration Data transfer interface

9. Software Image capture Image manipulation (Photoshop, etc.)

10. Image controls white balance color balance sharpen compression zoom (optical)

11. Image controls General rule of thumb: Don’t use most image control functions in-camera. Apply them afterward.

12. Remember: All rules of photography still apply!

13. Terms Capture: The act of taking a digital photograph

14. Terms CCD: Charge Couple Device, the image capture area in the camera

15. Terms Removable Media: Temporary storage of data in camera

16. Terms Formatting: The act of initializing or erasing images from removable media

17. Terms RGB: Red, Green, Blue The colors computers work with

18. Terms CMYK: Cyan, Magenta, Yellow, Black, The colors printers work with

19. Terms Pixel: The basic building block of digital (bitmap) images

20. Terms Mega Pixel: Millions of pixels; total number of pixels captured by a camera

21. Terms File format: “Container” into which digital data is stored

22. Terms File formats: TIFF JPEG RAW (NEF, etc.)

23. Terms Resolution: Number or size of pixels in an image

24. You say you want a Resolution…

25. Did you know…. All digital photographs are actually black and white images

26. Example: 2 bit color

27. Term Bit: Binary digit; 0 or 1, Black or white

28. Example: greyscale

29. Term Greyscale: An image rendered in black, white and shades of grey

30. Example full color

31. 2 bits, 4 bits, 8 bits, A dollar? No, a channel

32. Example another full color

33. Resolution Pixel depth/ bit depth: How many bits of information per pixel is captured

34. Resolution 2 bits x 2 bits x 2 bits = pixel depth of 8 bits

35. Greyscale An 8-bit greyscale image can render 256 different tones from black to white

36. Let’s do some math Red chanel=256 tones X Green chanel= 256 tones X Blue chanel= 256 tones =16,777,216 possible colors

37. Resolution Factors: pixel depth, image size and resolution (dpi) Affects file size

38. Resolution 8x10 image @ 600ppiimage @ 600ppi 1 bit (B&W)=3.6 MB 8 bits (greyscale)=28.8MB 24 bits (RGB)=86.4 MB 32 bits (CMYK)=115.2 MB

39. ATTENTION! The “powers that be” request that you pay specific attention to the following information

40. Resolution For commercial printing: dpi/lpi/ppi 300

41. Resolution @ 300dpi: 1 MP = 3”x 3” 2 MP= 3”x 6” 3 MP= 5.6” x 5.6” 4 MP= 6” x 6” 5 MP= 7” x 7” 6 MP = 6” x 20” 16 MP= 13”x13”

42. Resolution Please note that screen resolution is 72 dpi

43. Image controls Many found in-camera are also found in image manipulation software

44. Image controls Save images unchanged: treat like negatives backup in case of error

45. Image controls White Balance: Camera setting to match the lighting conditions

46. Image controls Color balance: Image settings between cyan/red, magenta/green, yellow/blue

47. Image controls Sharpen vs USM (UnSharpMask)

48. Terms Artifacts: Nasty, little globs of high contrast goo from oversharpening

49. Terms Noise: Specks in image due to long exposure time or high ISO

50. Example noise

51. Terms Interpolation: Creating pixels from existing pixels lowers image quality

52. Image controls Histogram: Chart of greyscale values in an image

53. OK, lets do the rest in Photoshop Shut down this foul Microsoft application!
