The power of iPhones for taking photos is quite good as it is, but there are always add-ons that can make the photo taking experience to the next level.
In addition to using tons of apps to make your photos look great in post, you can also use physical add-on features like lenses. Turata makes an HD lens for iPhones that can both take wide angle shots and close-up macro shots with great detail.
The lens just attaches to the phone with a rubber clip so it’s totally safe to use and it can even work on iPads and some other phones besides iPhones.
The wide angle lens is awesome for capturing group shots where everyone normally wouldn’t fit into the photo, and it’s also great for just getting wide shots of the scene at hand. The macro lens is perfect for taking photos of plant life or detail in any interior space you might be exploring.
