We are pleased to announce the release of Lens•Lab 1.0 for all iOS devices!
What is Lens•Lab? Here’s a short description:
Lens•Lab is a virtual lens simulation tool for photographers of all skill levels. It graphically illustrates how depth of field and field of view relate to your SLR camera and lenses.
Lens•Lab works with all iOS devices running firmware 3.0 or newer and works great with iPad and iPhone 4 retina displays!
