Actions
3 kinds of size!
- file size
- height and width
- dpi (pixel size)
print-outs have variable dpi. Depending on the capacity of the printer, the actual pixels change size
Scale images with photoshop to approximate print height/width and:
- ~100 dpi (web documents)
- ~300 dpi (home printers)
- >300 dpi (magazines)
More is not better! larger than necessary image file sizes used in a word document increases the word document's file size too.
internet images are always 72 dpi (height and dpi settings are ignored.)
Therefore optimized
-
thumbnails (~150px) and
-
enlargements (~800px)
are necessary.
More is not better! larger file sizes slow downloading time.
Always view images at "actual pixels" before sizing and optimizing.
- When increasing image size - use "bucubic smoother"
- When decreasing image size - use "bicubic sharpen"
