Best scanner for morphometry

[Jon]

I place 18-20 wings on to a microscope slide then set another slide carefully on top before placing it in the scanner.
You have to be careful not to move the slides while setting them on the scanner as you will end up with wings touching which means they will not be scanned.
2400 dpi seems to be plenty.
With AMM a small change in the position of points 0, 1 and 3 can make quite a difference to the value obtained as the distance between point 1 and point 3 tends to be very short in AMM compared to races such as carnica.
Drawwing often places point zero too far to the right which gives an artificially high CI value.

Edit for clarity - CI is calculated by dividing the distance between point 1 and point 3 by the distance between point 0 and point 1 so moving zero nearer to 1 raises the CI
