Why mess around with photos?

• Traditional photography is taking pictures of
  whats there it isnt right to add or change
  things
• Using filters, lenses and other tricks, you can
  get interesting pictures using 35mm film
• Your photos can be used in a range of ways, not
  just as snap-shots of events
• Special effects can make photos interesting,
  unique, dynamic and fun
• People pay large amounts for portrait photos that
  may be digitally altered to make them stand out
  (e.g. Venture)

How to get an effect whole picture

• You can change an entire photo very easily,
  simply by clicking on the effect you want
• In some cases, you will be asked to choose a
  colour
• Most effects ask you to choose widths, depths
  etc.
• You can use the preview to see how things will
  turn out (change the view from 100 to about 10
  for any chance of seeing it!)
• If you go wrong, simply click on Undo (although
  you may have to click Done first)

Applying an effect to part of a photo

• You can apply an effect to part of a photo by
  selecting it first (Rt ClickgtShow Selections)
• You can invert the selection so that you apply
  the effect to the rest of the photo
• The best way to work with parts of photos is to
  use layers
• Once you have made a selection, Copy (or Cut) and
  Paste it into the document this creates a layer
  (Rt ClickgtShow Layers for demonstration)
• If you use Copy rather than Cut, it pastes in the
  same location
• SAVE the document (rather than exporting it) as a
  .PDD file until you have finished working on it

Combining several photos

• You can work with several photos at a time
• You can cut something (or someone) out of one
  photo and put it into another
• If you want to apply an effect to all of the
  layers of a photo, you can merge the layers (by
  clicking on the arrow in the top right-hand
  corner of the layers box)
