I am planning a photography trip to Yosemite and one of the first and most valuable resources I have come across is Lewis Kemper’s Photographing Yosemite Digital Field Guide. The guide is available as a book and an iPhone app. I bought the iPhone app.
The guide includes a map that utilizes google earth to display landmarks in the park and directions to get there. If you are using the iPhone app, the GPS will give you directions and distance from your current location. The best part, in my opinion, is the planning section where Kemper displays his own gorgeous shots of the park, directions on how to get to those location, and details on how to get the shot including lenses, equipment and the exact settings he used. I am so excited that I will be able to take this very portable electronic guide with me so I can double check everything when I am on location.
There are also tools that display sunrise, sunset, moonrise, moonphase and the exact degrees of the location of the sun and moon. You can also calculate depth of field, HDR and exposure values. You can keep track of your shot list and upload your shots to facebook and twitter.
The iPhone app can be purchased on iTunes.
I am sure this guide will help me get the shots I want and come home with my own Ansel Adamsesque gallery. I can only hope!
