6-Images

(note: from Stefan Diller    www.stefan-diller.com)
to get colour in your SEM images:
- make good black and white images and add a lot of "Photoshop magic" to bring colour to the specimen
- use multiple detectors and perhaps also different kind of detectors (like SE or backscattered...) to get different signals back from the specimen and use these signals to attribute aesthetical colours to the image (and add some Photoshop magic...).
For example: I use the secondary electrons for getting a very fast separation of parts on specimen with a small interaction volume like hairs on insects or cells or substrate etc. The backscattered detectors (I have three) I use to get surfaces (topography) ad hoc separated in a different colour. You can also try to get more different images with different accelerating voltages and the best suited detectors for it... Also distance of the detectors to the specimen can make very different images...
There is a PDF from a MIKROKOSMOS article which describes my work, but only in German language:
www.elektronenmikroskopie.info/pdf/Mikrokosmos06-99.pdf (1 MB).  I am using a digital image acquisition system from point electronic, www.pointelectronic.de, which can handle up to 8 detectors and scan up to 4 detectors in a resolution of max. 16kx16k pixel. The scanning software has the ability to directly mix the signals 
from the SEM into a coloured image.

(note from Paul Calloman (callomon@ansp.org)
There is an important distinction between jpegs and tiffs, apart from the loss of data incurred via jpeg compression. A tiff file retains the information for each color (Red, Green and Blue for RGB; Cyan, Magenta, Yellow and blacK for CMYK) in a separate channel, allowing colors to be balanced and adjusted relative to each other. A jpeg mixes them into a single channel (which is why it's one third or one quarter the size of a tiff), which means they can no longer be treated individually.
Nowadays a good jpeg will be accepted by many publishers, particularly for online publication, but for color-critical work most still insist on tiffs.
