Native shutter speeds are off!

Response from developer

Version 2.0 now uses native shutter speeds, and also allows you to select between 1/2, 1/3, or both 1/2 and 1/3 stops.

great app

works well. Good for easy calculation of shutter speeds in different ISO ranges. That is really perfect for night shots. Like the shutter counter. An dddition of big stopper filter would be great. Thanks

Filter function not working

I just bought the Additional Features module for my iPhone 5, and the Filter function is not working. If I try to add a new filter (I need more EVs than the default filters provide), nothing happens -- a new filter is NOT added to the list. Scott, can you fix this?

I love cinematography, I hate math

It's always nice to have calculators like this on set. Without it, I'd imagine making a huge fool out of myself doing the math in head or by hand.. Greatly appreciated!

Great App

Works as you would think. I wish it would measure Ev, though I guess that would make it more of a meter.

It's good stuff!
