Hi all,

where can I find definitions of the terminology used for tiff, specifically, what is the difference between:

- multi-page
- multi-channel
- image bands
- image layers

regards
Murray

Look in the TIFF specifications.

Channels correspond to red, green, blue for example.
Bands are one form of specifying how r,g,b values should be formatted in a channel -- eg. all red, then all green then all blue, rather that line interleaved or pixel interleaved.
Pages correspond to different images in the same file
Layers show how different images are mixed together to form one image.
