Camera Controls And Photoshop

  2. 2. Are you familiar with all of the buttons and what they can do for you?
  3. 10. <ul><li>PIXEL ミ Picture Element: digital photographs are comprised of thousands or millions of them; they are the building blocks of a digital photo. </li></ul>
  4. 12. <ul><li>uncompressed (an 8 megapixel camera will produce a 8 MB Raw file) </li></ul><ul><li>the complete (lossless ) data from the camera’s sensor </li></ul><ul><li>higher in dynamic range (ability to display highlights and shadows) </li></ul><ul><li>lower in contrast (flatter, washed out looking) </li></ul><ul><li>not as sharp </li></ul><ul><li>not suitable for printing directly from the camera or without post processing </li></ul><ul><li>waiting to be processed by your computer </li></ul>
  5. 13. <ul><li>compressed </li></ul><ul><li>fairly small in file size (an 8 megapixel camera will produce JPEG between 1 and 3 MB’s in size) </li></ul><ul><li>lower in dynamic range </li></ul><ul><li>higher in contrast and sharper </li></ul><ul><li>immediately suitable for printing, sharing, or posting on the web </li></ul><ul><li>processed by your camera </li></ul>
  6. 15. <ul><li>RAW files are bigger and take more space on your memory card </li></ul><ul><li>RAW files need post production </li></ul><ul><li>RAW files are better quality </li></ul><ul><li>RAW files give you much more control over how the image will look </li></ul><ul><li>Better for professional photographers </li></ul>
  7. 16. <ul><li>JPEG files are smaller in size and take less space to store </li></ul><ul><li>JPEG files do not need any post production </li></ul><ul><li>JPEG files loose richness , detail (sharpness), color range </li></ul><ul><li>JPEG files give you less ability to control the final image </li></ul><ul><li>Better for snapshots </li></ul>Take one photo in raw and one in jpeg. Can you see the difference?
  8. 19. <ul><li>EV means exposure value </li></ul><ul><li>The range over which you can manually over or underexpose to lighten or darken the image </li></ul><ul><li>Usually, the range of adjustment goes from +2 to -2 EV in 1/3 steps </li></ul>
  9. 23. <ul><li>The camera automatically takes three or more shots with a different exposure for each frame </li></ul><ul><li>One image at the camera measured exposure , a second at a negative exposure compensation (usually -1/3 EV , though some cameras allow you to specify the amount), and a third at a positive exposure compensation (usually +1/3 EV , though some cameras allow you to specify the amount) </li></ul><ul><li>Useful option for taking HDR scenes </li></ul>
  10. 24. Find the AEB on your camera
  11. 28. <ul><li>Simple graph that displays where all of the brightness levels contained in the scene are found, from the darkest to the brightest </li></ul><ul><li>Displays a photographs dynamic range </li></ul><ul><li>In camera light meter </li></ul>
  12. 33. <ul><li>THOUGHTFUL TIMING </li></ul><ul><li>COMPOSITION (RULE OF THIRDS) </li></ul><ul><li>PERSPECTIVE </li></ul>
  14. 41. <ul><li>Refers to the placement of the sub ject within the frame of your photograph </li></ul><ul><li>Places the main subject off center and away from the center of the frame. As a result, photos can look more dynamic and interesting </li></ul><ul><li>Place points of interest in the intersections or along the lines </li></ul>
  15. 45. <ul><li>Perspective is the way that an object appears to the eye </li></ul><ul><li>Dependent on focal length and picture angle </li></ul><ul><li>Creative way of looking at your photographic subject </li></ul><ul><li>Example ALEXANDER RODCHENKO , BILL BRANDT , HENRI CARTIER-BRESSON </li></ul>
  16. 46. Boring flowers become an amazing photo
  19. 57. BILL BRANDT
  20. 60. <ul><li>Practice photography on a regular basis </li></ul><ul><li>Avoid common photographic mistakes like over exposure, under exposure, or blur </li></ul><ul><li>Look at photographs of others to inspire </li></ul><ul><li>Read your manual and learn about your camera functions </li></ul><ul><li>Learn better compositional techniques </li></ul><ul><li>Don’t be afraid to experiment </li></ul>
  21. 61. PERSPECTIVE EXERCISE <ul><li>Find an object/subject </li></ul><ul><li>Shoot 15 different ways (using rules of perspective and composition) </li></ul><ul><li>Get creative with angles </li></ul><ul><li>30 minutes </li></ul>
  22. 62. ADOBE CAMERA RAW <ul><li>used primarily to read and process raw image files </li></ul><ul><li>resulting images can be processed by Photoshop </li></ul><ul><li>considered a plug-in but comes with the program Photoshop </li></ul><ul><li>opens automatically when adjusting a .raw file </li></ul><ul><li>reads your camera default settings (or custom) </li></ul><ul><li>allows control over white balance, histogram, crop, sharpness, contrast, saturation and more </li></ul>
  23. 64. WHITE BALANCE <ul><li>3 ways to adjust white balance </li></ul><ul><li>White balance eye dropper, settings, or temperature and tint </li></ul><ul><li>allows control over final color balance </li></ul>
  24. 65. <ul><li>controls brightness of an image </li></ul><ul><li>moves in F-stop values (f/22-f/1.8) </li></ul><ul><li>latitude based on quality of camera and lens used </li></ul><ul><li>Using the alt button you can find ‘clipped’ pixels of pure white if over exposing (means losing detail in highlights) </li></ul>
  25. 66. <ul><li>Much like using the black eye dropper in levels in Photoshop </li></ul><ul><li>Allows control over dark details in image </li></ul><ul><li>Holding down the alt button allows you to see if you have ‘clipped’ any shadow detail in the image </li></ul>
  26. 67. <ul><li>overall lightness adjustment </li></ul><ul><li>gamma adjustment </li></ul><ul><li>maintains all of the image details (shadows and highlights) </li></ul><ul><li>No clipping </li></ul><ul><li>Histogram not really affected </li></ul>
  27. 68. <ul><li>is created by the difference in luminance </li></ul><ul><li>measures difference between the colors (how stark or not) </li></ul><ul><li>think of a black silhouette on a bright white sky (high contrast) </li></ul>
  28. 69. <ul><li>changes intensity of a photographs colors </li></ul><ul><li>high saturation will result in special effects and brighter colors </li></ul><ul><li>low saturations will result in a black and white effect </li></ul><ul><li>increasing too high will result in color shifts when printing </li></ul>
  29. 70. <ul><li>best to zoom to 100% view of image </li></ul><ul><li>used to enhance &quot;sharpen&quot;, the detail of an image </li></ul><ul><li>sharpening isn't about making a blurred image sharp; it's about getting the optimum sharpness from a photo that was shot sharp </li></ul><ul><li>Smoothing also known as antialiasing, is the electronic process of eliminating or reducing noise in an image </li></ul><ul><li>or averaging pixels with their neighbors to reduces contrast and simulate an out-of-focus image </li></ul>
  30. 71. <ul><li>R-red channel </li></ul><ul><li>G-green channel </li></ul><ul><li>B-blue channel </li></ul><ul><li>measures color's intensity distributed throughout the image </li></ul><ul><li>an RGB histogram produces three independent histograms and then adds them together, irrespective of whether or not each color came from the same pixel </li></ul><ul><li>RGB histograms can show if an individual color channel clips </li></ul>
  31. 72. <ul><li>histogram is a graph counting how many pixels are at each level between black and white </li></ul><ul><li>black is on the left </li></ul><ul><li>white is on the right </li></ul><ul><li>the height of the graph at each point depends on how many pixels are that bright </li></ul><ul><li>lighter images move the graph to the right </li></ul><ul><li>darker ones move it to the left </li></ul><ul><li>can be used as in camera light meter for exposure </li></ul>
  32. 74. <ul><li>a little bit of clipping is OK on things like the highlights of sun dancing on water (specular highlights) </li></ul><ul><li>overexposed digital images are almost useless. Anything that washes out to white is gone forever </li></ul><ul><li>images that are too dark are easy to correct later; just drag the right slider in Photoshop's Levels command to the left to meet the edge of the histogram </li></ul>
  33. 75. In this histogram you'll see a peak on the left at 100% black, even when overexposed. This is the dark shadow on the left of the photo. This shows that the camera's contrast needs to be lowered, or better still, add fill light in the shadows.
  34. 76. Overexposed histogram means loss of detail in the highlights
  35. 79. <ul><li>taking your photograph to new creative heights </li></ul><ul><li>useful tips that will improve your Photoshop </li></ul><ul><li>skills such as editing, enhancing, practice, tutorials, subscribing to galleries and forums and reading magazines </li></ul>
  37. 81.
  38. 82. The Crop Tool allows users to redefine their active image area but not resize the ENTIRE image. It’s sort of like cutting out a smaller picture from a larger photo with a pair of scissors.
  39. 83. There are several healing tools in Photoshop which are used to repair imperfections in images, or handle blemishes and red-ey
  40. 84. With the Clone Stamp Tool, a user may select a source starting point somewhere on an image, and then paint elsewhere using that starting point as a reference, effectively cloning the source.
  41. 85. The Eraser Tool can be used to erase parts of an image, selection, or layer
  42. 86. The Sharpen Tool is used to sharpen edges in an image, while the Blur Tool burs edges. The Smudge Tool smudges an image, similar to using fingerpaint.
  43. 87. The Dodge Tool lightens parts of an image while the Burn Tool darkens. The Sponge Tool is used to saturate, or desaturate parts of an image.
  44. 91. <ul><li> </li></ul><ul><li> </li></ul><ul><li> </li></ul>
  45. 92. <ul><li>Photoshop functionality can be extended by add-on programs </li></ul><ul><li>most common type are filter plug-ins that provide various image effects </li></ul><ul><li>many free plug-ins online </li></ul><ul><li> </li></ul><ul><li> </li></ul>
  46. 93. The best way to learn anything new is to experience it for yourself
  47. 94. <ul><li> </li></ul><ul><li>subscribe to a few that you like the most so you don't miss out on new posts (you may also want to bookmark other tutorial sites in case you want to find them in the future) </li></ul>
