Presentation Transcript

  1. Nice Calm Scene. (You’ll need it.)

  2. Skills • Getting files off of the camera or scanner • Archiving • Choosing and adjusting image file type • Editing • Scaling size/resolution for web/e-mail • Scaling size/resolution for print

  3. Terms and Concepts • Pixels • Image Resolution • “Output” or “Physical” Image Size • Color Depth • File Formats

  4. To the drawing board…

  5. From the drawing board… File Formats

  6. “Web Friendly” File Formats • JPEG images (*.jpg, *.jpeg, *.jpe, *.jfif) - many compression levels (lossy) • CompuServe images (*.gif)- compression format: LZW (lossless) - special: interlaced, non-interlaced • Portable network graphic images (*.png)- compression format: LZ77

  7. JPEG/JPG “Photographical” • JPEG is designed for compressing either full-color or grey-scale digital images of "natural", real-world scenes. It does not work so well on non-realistic images, such as cartoons or line drawings. • Remember, the 'P' in JPEG stands for 'Photographic'. It was designed to be used to compress photographic image data. (Joint Photographic Experts Group)

  8. GIF “Solid colors and lines” • GIF images can contain a maximum of 256 colors (8 bits) or less… (Graphics Interchange Format) …if you create a GIF image of a red arrow, you can customize the file to have only two colors, red and white.

  9. PNG • PNG: Essentially ‘Extended’ GIF Images. Allows for up to 24-bit color including control of opacity. Saving, restoring and re-saving a PNG image will not degrade its quality. PNG does not support animation like GIF does. “Patent-Free”

  10. “Edit Friendly” • Uncompressed or lossless compression • Saved, edited, saved, edited without penalty • Good for archives… (Why?)

  11. “Edit Friendly” (web poor) file formats(Either uncompressed or lossless compression) • TIFF images (*.tif, *.tiff) - uncompressed (Compressed: packed bits, LZW*, CCITT T.4, Deflate, new style JPEG…) • Standard Windows bitmap images (*.bmp)- uncompressed • Photoshop images (*.psd, *.pdd)- uncompressed • RAW images (*.raw) - shockingly uncompressed

  12. Step A. • Archive your important photos in their BIRTHDAY SUITS. (native, un-edited, un-resaved, happy, naked state) • (Meaning, make a copy and DON’T work on the copy…)

  13. Step B • If you will be doing lots of saving, editing, saving, editing… FIRST, convert to a lossless or un-compressed form.

  14. Step C • Edit and Adjust • For appropriate pixel size • Cropping, color, orientation…

  15. Terms • Pixels • Image Resolution • Image Size • Color Depth • File Formats

  16. Step D. • Save in the desired production format… Done!

  17. On to software…
