Wow. Well welcome first. You laid a lot on us for your first post. If my copying works here, we'll be in good shape.
THIS IS A COPY OF TOM STEELE'S POST: from another thread, I don't know how to quote from a different thread:
" I'll close with my favorite recommendation:
This is a very good book for starters... It is easy to understand, covers the basics very well, is up to date and will get you to the next step where you can say you know more than most people with a camera in their hand. From there, you can read plenty of others. But this is a good starting point: "
The Photography Bible
so you might want to start here with this book. I have looked through it at Barnes an Noble too, and it has great info in it.
Can I ask why you bought so much stuff before understanding some of the basics? Have you read through any of our past threads or checked out the search box at the top?
I don't even know where to begin! but welcome again... there's much to learn here.
