How Do I Learn To Process Imagery? Options

[RGMars]

Does anyone have advice for someone who wants to edit their own photos? I want to look through the archives of missions like Voyager or Viking but I don't know where to start software wise (or how to use it). My operating system is MacOs, and I don't have Photoshop. All help is appreciated...

From the planetary society website, what is likely an excellent introduction:

A short series of classes by Emily Lakdawalla on how to process space images, conducted in 2009 and 2010. The classes require you to install either GIMP (free, open-source image manipulation software) or Photoshop. GIMP is used for most in-class demonstrations, but the two software packages are very similar. The classes were originally conducted via WebEx, so you may need to download the WebEx player in order to view them.

WebEx is a Cisco video conferencing platform for Windows, with some MacOS support. I've never used it myself, and the current WebEx MacOS player is not supported on my aging Snow Leopard system (10.6.8), but you might be able to run it on a more recent version of the MacOS.

Thanks! Yes, WebEx works on the newest version of MacOS! I realize that that you mention that these video tutorials are essentially an introduction. Could you point me in the right direction for some more advanced information that I can access in the future?
Thanks!
