Reddit mentions of The Moment It Clicks: Photography Secrets from One of the World's Top Shooters

I like the hotshoe diaries and the moment it clicks, both by Joe McNally. Hot Shoe diaries is more lighting specific, and really focuses on using small flashes to get good results.

Learn to improvise. How cute does a home have to be for you to clean up one little corner to shoot? Only the part that's in-frame needs to be cute. You should read Joe McNally's book The Moment it Clicks for dozens of inspiring anecdotes about how he improvised under difficult or even impossible conditions.

Problem-solving is what it's all about.

What color did you get?

I know the feeling. When I bought my K200D it seemed like a ton of money and forever before it arrived.

As soon as you can start using the AF-200 and see what it does and doesnt do to images. Then get on the Strobist and learn what you can do with off camera flash. If you really want to get into that kind of photography it is extremely rewarding. You create light that doesnt exist. Read "The moment it clicks" and "Hot Shoe Diaries" and be prepared to be addicted. When you are ready to take the plunge, go to Gadget Infinity and check out the Cactus RF60 can do.

Not sure that qualifies for you, but McNally's The Moment It Clicks includes images (with explanations) from all the way back when he was shooting film... Tons of tricks, some of them from a time such that they may not all apply as much now.

That's some quality glass to start out with - I'm a bit jealous!

Based on your hardware I'll assume you're not entirely new to photography so, suggestions for next steps, aside from taking photos:

Books/Websites to read:

• The Moment it clicks - I got a big kick out of this book, but some didn't like it.
  
  
• Susan Sontag's On Photography is a thought-provoking look into the psychology and philosophy of photography. On some level it feels slightly dated, but it's still incredibly relevant - probably more relevant than when it was originally written.
  
  
• Digital Photography School is an extremely valuable online resource for people getting into photography.
  
  
• Strobist is almost required reading for people wanting to introduce artificial light into their photos.
  
  
• Flickr is a huge site, and a very useful place to find like-minded people. Search their groups for the kind of photography you're interested in and you're sure to find groups full of kindred spirits (and the occasional troll).
  
  Secondly, I'd suggest you pick some masters to emulate/study/admire. There are far too many to list so I'll just pop down a few that got my juices flowing when I first got into photography:
  
  
• Henri Cartier-Bresson
  
  
• Ansel Adams
  
  
• James Nachtwey
  
  
  Cartier-Bresson once said "your first 10,000 photos are always your worst", so get out there and take some! Then take some more :-)
  
  Edit: Fixed formatting.

Just a few of the lighter purchases I've made this year that I can recommend to anyone. Maybe these are more like stocking stuffers but they're definitely must-haves.

• Nikon Lens Pen
  
• Giottos Rocket Air Blaster
