First space imaging class tomorrow, 10:30 a.m. Pacific / 18:30 UT

NOTE: Due to problems with my Internet service, I had to postpone the class, and don't know yet when I'll be able to reschedule it. Sorry!


If you have sent me an email asking to register for the first of my classes in amateur image processing tomorrow at 10:30 a.m., you should just have received an email from "Louis Friedman" (whose name is the one listed on our WebEx account) with the meeting details. The topic of the first class is: "Images Are Data." I'll go through how images actually represent scientific data, some very basic image processing stuff like histogram adjustment and what that does to the data, and what RGB color images are and how to compose them. After the class I'll have a Q and A where you can ask questions by chat and I'll answer on video.

I just noticed that the reminder email lists Lou's email address to contact if you have questions. You're free to email Lou all you want, but if you actually want an answer about this class, it'd be better to email me at blog at planetary dot org.

There are still spots available to participate live, so if you'd like to be added to the list, send me an email right away. I won't have time to add anybody tomorrow, since the LCROSS folks kindly scheduled a press briefing during the time I had planned to be preparing!

I received several emails asking me to cover both Photoshop and GIMP. After creating my slides, it seemed that I should be able to do the few demonstrations in GIMP first, then run through the same operations quickly in Photoshop. So if you are a Photoshop user, you do not have to install GIMP.

After I conduct the class, I'll post a link to where you can download and view it offline. But I may have to write an LCROSS story first, so it may not be available immediately.

To everyone who'll be participating tomorrow, I will need to ask for a little bit of patience, as this'll be the first time I've conducted a meeting using WebEx; there'll probably be a few "ummm--ahh--where's that tool now? Oh yes, there it is" punctuating my talk. Things should get smoother with time.

Here we go!
