With LightMeter you can turn your iPhone 3G-S into a simple exposure meter. LightMeter makes use of the new auto focus camera built into the iPhone 3G-S to determine the exposure of any scene you capture. Simply start LightMeter, take a photo and read the exposure for that scene from the exposure dial. It really is as easy as that.
So far, I 'm very impressed!!! I've made comparison to my $100 Sekonic Twinmate L-208
analogue meter, my Canon 40D
, and my Olympus E-P2
's built in light meter. The result is consistant.. about 1/3 to 1 stop over everytime! (or about half a EV value)Well, you might say it's not accurate... but the thing is, every light meter is a bit different, and I haven't developed the roll I've taken with my Rollei 35
to compare..but I must say, @ $2.99, you really can't complain!!! AND WHEN it's C O N S I S T E N T like this, I can just use it's built in "filter" setting to minus 2/3 of a stop so it's "calibrated"
More details on the app here on their official website
If you're shooting analogy all the time, you should probably have a very good idea of exposure under most situations. But if you happen to be using a iPhone 3Gs already, a few bucks would allow you to have a meter with you ALL THE TIME!!! now who wouldn't want that!
