Composition matters
- centered subject is not interesting
- use tight cropping to draw the eye
- natural lines also draw the eye
- use interesting light
Rule of thirds
Which one uses the rule of thirds?
F-stop or depth of field

Tonal range
- 0 is black and X is white (remember html black is #000000)
- In RGB spectrum, 255 is essentially white light while 0 is black
Vector vs. raster

File formats
- .psd (master photoshop file. Always keep this and save often!!!)
- .gif (supports animation and transparency, but not gradients)
- .png (supports transparency and gradients but not animation)
- .jpg (“lossy”)
Which is best for photos? Which is best for simple logos?
Redistributing pixels compresses or spreads out the pixels in the document. The file size will remain the same.
Resampling pixels down throws pixels away. Sampling up is a bad idea as software doesn’t know how to do it well – image gets fuzzy (White Space pg. 143)
Image size and resolution
300 dpi (dots per inch) for print — do NOT check “resample image” box
72 ppi (pixels per inch) for web — check “resample image” box
