photography calculator for android

just dis­covered pho­to­graphy cal­cu­lator which is an android applic­a­tion that helps cal­cu­late hyper­focal dis­tances for photography…mostly useful for land­scapes but it could be used for macro work too i suppose. you enter your camera type, effect­ive focal length, aper­ture and dis­tance to subject. it then gives you the hyper­focal dis­tance for focus­sing. it also includes a field of view calculator…which shows the number of images required for pan­or­amic work. it has details for my sony a200 and 1476 other cameras.
haven’t tried hyper­focal dis­tance tech­nique before so this tool should make things slightly simpler. $2.99 well spent i feel. see below for a couple of screen­shots…
