I just found this thread this afternoon. Great idea! From now on I will post my plans here. Lets keep it going.
I will begin by posting a write-up I was asked to do for the International Free Flight Symposium that gives step-by-step instructions on how I prepare my plans using Photoshop. If you can scrounge a version of Photoshop you only need to know how to open a file in Photoshop to begin learning.
. . . Well, I tried to post the version of the instructions that has all of the color screen captures that illustrate the procedures but I find the file size is larger than is permitted for this website. I will post the stripped-down version with no color screen captures. Should anyone want the full version, just write me at firstname.lastname@example.org
and I will e-mail it to you.
Please post any questions you may have and I'll do my best to answer them here so we all can learn.
