EV ALTERNATIVES gives you a dual combo alternatives of ISO, APERTURE and SHUTTER SPEED SWEET SPOTS is not always accurate, but in many cases lenses has its sweet spot at about 40% up on the aperture range. SETTINGS lets you choose which stops you want to see in the ND STOPS PAGE and at what EV (exposure value) interval in all pages. To see more apps like this, go to www.discobajas.com
