You went an unusual way... Well done!
I consider the T90 anything but a beginners camera. Because a beginner has to read and understand a basics textbook, the same time read and understand the manual, or even better a dedicated book on this camera. I got the dedicated book at hand: 270 pages just on handling, no photography guide as some of such books in earlier times.
I'm interested in that book, got a picture of the cover or copyright page?
