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?

Try it with this photo.

F-stop or depth of field

low f stop

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
Bitmap-vs-Vector2

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

We don’t often see accidental pixels because screen quality is advancing.

Intentionally downgrading image quality can have a special effect.
