1. Images and PowerPoint
Scanners usually try to save an image as a TIF or Bitmap
Don’t use .bmp, or .tif files in PowerPoint
They are too big
They will make your presentations unnecessarily large
Save as a .jpg
All photographs
Compression settings
Larger #’s = great quality and larger file sizes
Anything with more than 256 individual colors
Save as a .gif
Anything with less than 256 colors
Large blocks of color
Newspaper cartoons
Scanned paper documents
Black & white drawings

2. What is a pixel? The basis of all digital imaging
Small square block of color information
Does not have a set size
The more pixels – the higher the “resolution”

3. Your screen is a big piece of
Image Delivery
Your screen is a big piece of
graph paper
1024 pixels
768 pixels

4. Scan what you need… Don’t over-scan your image:
“Hoping they will look better”
For full screen images in PowerPoint
You don’t need more than 1024 x 768 pixels
The computer cannot display anymore than this!
This is a moving target as technology changes

5. Image Style Exercise care when making graphics
Don’t use two-color bitmaps for graphics
Don’t stretch or expand graphics
If an image looks jagged redo it
If you have problems ask someone for help

6. Anti-aliasing Appears smoother
Adds some “stepped” colors around the edge
Should always be used with on screen digital imaging and logos

7. No Anti-aliasing

8. Web Images Try to keep it the same size that it was on the web
Stretched images will always look worse
