Colorize
SEM images are all grayscale. It is possible to colrize these images for aesthetic - and sometimes - scientific reasons. This page has a collection of SEM - and some light microscope - images in their original format as well as colorized. In the original and a colorized example of each there is also a micron scale. All images are in a compressed (JPEG format) for easy downloading. These JPEG forms can be uncompressed into a TIFF format to use with the measuring tools described below.Imaging Tools to analyze images.
You will need a copy of NIH Image software for the Macintosh and Scion Image software for the Windows . Both software applications can be obtained at the Center for Image Processing for Educators : CIPE . It will be necessary to convert the images from their JPEG (compressed) format to a TIFF format to use in NIH Image or Scion Image. Graphics programs that can do this are probably already on your computer - or you can download a freeware example on the WEB. You can also obtain Image/J software from this same site. This Internet software allows you to use a number of image formats, including JPEG.Get those Images!
A collection of ideas on how to obtain - in an inexpensive manner - images that can be used in biology and general science. There are also links to other sites offering further suggestions.Your own SEM!
What are some of the considerations to keep in mind if you want to own your own scanning electron microscope. What the author has learned - easily, and not so easily - in the several years of operating such an instrument at the secondary school level.
