I got a splendid Photoshop book called, The Abobe Photoshop CS4 book, for digital photographers by Scott Kelby. It is truly a well layed out book that covers some great subjects. I took a couple of my older shots and used some techniques in the book and it made a good shot a much better one. I just started too. I highly recommend this book.
Prevailing Conditions recommended it to me, I was picking his head on how he got such beautiful rich colors in his pictures.
