Taxacom: digital camera question

[John Grehan]

Hope someone on Taxacome has microscope camera expertise that can help me
with a question concerning digital camera capability meeting publication
needs. I am looking at buying a 'cheap' (less than $1,000 US) dissecting
microscope and digital camera through Amscope. They have cameras ranging
from 1 to 20 megapixels, but I have no idea how that relates to dpi where
publications usually require at least 300 dpi. Can anyone clue me in on how
to know what megapixel size will likely work to give me a sharp enough
image for publication? Currently looking at a 5 megapixel camera which
brings the setup well within my limits whereas 10 megapixel goes just over.
Any enlightenment much appreciated. I am a total moron when it comes to
digital camera tech.

Thanks.

John Grehan
