Another storm with low temps, high winds, and 6 inches of snow closed schools all over West Virginia yesterday and gave me the time to experiment some more with animation.
I have Photoshop Elements but it's so complicated I haven't used it much and became frustrated trying to understand how to use it so I went back to the gifmaker website. [I need to study up in the couple of books I have on how to use PS Elements because it's probably the best way to go.]
The animation shows Io's shadow beginning a transit followed an hour later by Europa's shadow. Meanwhile the Great Red Spot rotates from the central meridian to the limb.
I wish I could dissolve from one frame to the next but gifmaker doesn't have that function. I'm hoping PS Elements does. I also wish I had more sketches to put in the sequence. Comments welcome.
