  11. 11. No. 3 Analysis <ul><li>Techniques Used </li></ul><ul><ul><li>Paint brush tool </li></ul></ul><ul><ul><li>Blur tool </li></ul></ul><ul><ul><li>Magic Wand </li></ul></ul><ul><ul><li>Fill (bucket) tool </li></ul></ul><ul><li>Summary </li></ul><ul><ul><li>Because of the bright hues and lighting in the environmental image, a color balance had to be established by modifying the columns of the canyon with dark shadows. </li></ul></ul><ul><ul><li>The theme (a burning hot hell with a beautiful angel) of the combined image represents a difficult collaboration between dark cold black shades, and hot bright yellow heat from the heavens above. </li></ul></ul><ul><li>Problems </li></ul><ul><ul><li>Because of low resolution of the originating images, there was little available room for changes to contrast or brightness overall. </li></ul></ul>

  14. 14. No. 4 Analysis <ul><li>Techniques Used </li></ul><ul><ul><li>Liquify (plus) </li></ul></ul><ul><ul><ul><li>Pucker </li></ul></ul></ul><ul><ul><ul><li>Bloat </li></ul></ul></ul><ul><ul><ul><li>Reconstruction </li></ul></ul></ul><ul><ul><li>Paint Tool </li></ul></ul><ul><li>Summary </li></ul><ul><ul><li>Because of the close proximity of the focal point to the camera lense, this subject was an excellent opportunity for modifications to skin tone areas of the image where modifications of a significant degree were possible. </li></ul></ul><ul><li>Problems </li></ul><ul><ul><li>As changes to the shape of the object were magnified around the eye sockets, the lense and iris became distorted in shape. </li></ul></ul><ul><ul><li>This uncovered the secrets of the modifications and decreases the life-like appearance of the final image. </li></ul></ul>

  17. 17. No. 5 Analysis (part 1) <ul><li>Techniques Used </li></ul><ul><ul><li>Lens Flare </li></ul></ul><ul><ul><li>Shape tools </li></ul></ul><ul><ul><li>Blur filter </li></ul></ul><ul><ul><li>Stylize filter </li></ul></ul><ul><ul><li>Blue tool </li></ul></ul><ul><ul><li>Smudge tool </li></ul></ul><ul><li>Summary </li></ul><ul><ul><li>These techniques would be more useful in non-professional uses, such as for organizational brochures and web graphics </li></ul></ul><ul><ul><li>Without finer tuned and less holistic automatic changes, the final effect is an obvious departure from realism. </li></ul></ul>
  18. 18. No. 5 Analysis (part 2) <ul><li>Lens Flare </li></ul><ul><ul><li>Creates a circular glow </li></ul></ul><ul><ul><li>Move cross-hair with mouse to desired centroid </li></ul></ul>

  20. 20. No. 6 After
  21. 21. No. 6 Analysis (part 1) <ul><li>Techniques Used </li></ul><ul><ul><li>Layer Mask Cutout w/Paint Brush </li></ul></ul><ul><ul><li>Layer Mask Light filter (exposure) </li></ul></ul><ul><li>Summary </li></ul><ul><ul><li>This was the most difficult and time consuming problem. </li></ul></ul><ul><ul><li>First, the entire scene, other than a few grassy areas in the background was underexposed </li></ul></ul><ul><ul><li>However, the grassy areas in the background were almost white </li></ul></ul><ul><ul><li>Part of the problem was the high ISO used </li></ul></ul><ul><li>Problem </li></ul><ul><ul><li>This is a classic problem in Photoshop. How can you increase the whole photo lightness just slightly, while simultaneously lowering the lightness in some areas, and GREATLY increasing the light exposure in others??? </li></ul></ul>
  22. 22. No. 6 Analysis (part 2) <ul><li>Exposure Histogram </li></ul><ul><li>Right side is bright </li></ul><ul><li>Left side is darks </li></ul><ul><li>Right end is dragged left </li></ul><ul><li>Convex curve dragged left </li></ul><ul><li>Results </li></ul><ul><li>Brightest areas are made lighter </li></ul><ul><li>Dark areas also made lighter </li></ul><ul><li>This is a filter layer </li></ul>
  23. 23. No. 6 Analysis (part 3) <ul><li>The background layer in this case was only preserved as a backup </li></ul><ul><li>Next, the layer 1 is being “masked” by a light contrast layer, by manipulating the curve over the histogram </li></ul><ul><li>Finally, the second copy of the background (“layer 1 copy”) was masked by a cutout layer </li></ul><ul><li>The paint brush (color: black) was used to ‘cut-out’ the parts of the top layer image copy with 50% opaqueness </li></ul>
