My favorite photography iPhone and iPad apps

My favorite and most-used photography apps for the iPhone and iPad are:

• FlickStackr - if you use Flickr this is a great mobile interface to it
• Camera+ - great for taking photos from the iPhone, then processing them
• Photogene for iPad - together with the camera connection kit, I can transfer photos (even RAW files) from my camera to the iPad, edit them on the iPad, and then upload them.
• The Photographer's Ephemeris - pick a place on earth and a date and calculate the time and angle of sunrise, sunset, moonrise, and moonset. Great for planning outdoor photos.
• iDoF Calc - calculates depth of field
• LightStudio - useful for pre-visualizing how different lighting schemes will look
• Strobox - only useful if you do complicated lighting with multiple lights, but great for easily creating diagrams of that to refer back to later
• Advanced Photoshop magazine for iPad - learn more about Photoshop
