Courses for learning Photoshop

I've been using Lightroom for about 18 months and I've recently purchased Photoshop CC. I'm looking for recommendations on courses for learning how to use PS effectively. Any suggestions would be greatly appreciate.

I am still learning new techniques from Seans videos

Thanks - I'll take a look at both.

Adobe has a series of free Youtube videos (The Photoshop Playbook) which touch on the basics: https://www.youtube.com/user/Photosh...dd&shelf_id=10.

Adobe also has some free instructional videos with their "evangelist" Julieanne Kost (she's an excellent teacher): http://tv.adobe.com/show/adobe-evang...ulieanne-kost/

And there are two superb books on Photoshop that I highly recommend:

(1) Martin Evening's "Adobe Photoshop for Photographers" (http://www.amazon.com/Adobe-Photosho...ning+photoshop

(2) Lesa Snider's "Photoshop the Missing Manual" (http://www.amazon.com/Photoshop-CS6-...missing+manual)

Evening's book is excellent. You might have a look at Tim Grey's video courses. I haven't looked at them but he has a good reputation. I subscribe to his daily newsletter (free) and his inexpensive monthly Pixology e-magazine.

+1 for Sean Bagshaw and Julieanne Kost. They are excellent instructors.

Thanks to everyone for your excellent recommendations.

Another program I found is Glenn Bartley's "Post Processing - A Guide for Nature Photographers". It's reasonably short and appears to cover all the basics. The main advantage is that his examples are all bird photos. I plan to start there and then dig into Sean Bagshaw's more comprehensive course, followed by Martin Evening's book.

Highly recommend Tim Grey, Arthur Morris's Digital Basics File, Robert Otool's APTATS, and Photoshop CS for Nature Photographers by Ellen Anon is an excellent resource that cover alot from basic to advanced.
Some of the others are good but alot of them are almost more graphic art stuff, and not as applied to bird photography. I'm sure Glenn's book was a great place to start too.
