Project 3 In Class Seashells

Remember, 

Image > Adjust > Hue Saturation or Levels!

To pin point differentiating color to select with Marching Ants use the regular Lasso Tool to draw AROUND the object loosely and wide. Then select the Magic Wand Tool after connecting the Lasso ends. Go into the light area (background color) outside of the image but inside the Lasso selection, press ALT. Should make Marching Ants group directly onto the edges of the main image (can change how Ants group by Tolerance on the top Toolbar).

To edit using Lasso
-Shift = adds pieces
-ALT = removes pieces 

To create a perfect shape around your image using the color variation differentiating from foreground and background, use Marquee Tool + Shift

To move Pixels in Marching Ants to another area, use the Move Tool 

Hand Tool + Spacebar = Zoom + ability to move, double click to Zoom out
Hand + ALT = Subtract View
Hand + CTRL = Zoom
CTRL + D = Deselect
To keep Marching Ants but resize something, use Spacebar in unison with Mouse
