TEXTBOOK REFERENCE: Photography, (Upton, London) Ch 7 - Adjusting / Compositing

LAYERS

- think of a clear page above your image, you can have as many as you want
- layers add file size, they use RAM, so more layers might slow your computer

ADJUSTMENT LAYERS

-the ultimate undo
-keeps your image adjustments separate from your image
-stores information as a mask
-click view button to see image with / without the adjustment
-ALWAYS KEEP A WORKING PS DOCUMENT WITH LAYERS INTACT
-save your flattened Tiff for printing under a different name

SELECTIONS

-use any of the painting and drawing tools to modify your selection
-use pre-set shapes in marquee tools or lasso tools
-use magic wand to select by color
-modify your selections by SIZE, FEATHER, EXPAND/CONTRACT..
-click mask icon at bottom of your tool bar to edit using quick mask – your selected areas will appear in 50% red, so you can see what you are selecting
-sometimes it is easier to select the area you DON’T want and then INVERSE SELECTION

COMPOSITING

-to make a believable composite, choose images that have the same light and color contrast
-or adjust your images separately until they match
-use images of the same size, if you change the size of one selection to fit into the background of another image, they may be different resolutions and one will look pixelated
-feather your selections before you combine, you will have to play around to find the right measure of feathering, it will soften the edges of your selection, to much is just as bad as too little
-since you are using random combinations (or somewhat random), play around with opacity before you start cutting, experiment with new spaces and new forms, don’t worry too much about it being logical
