Flying into the Grand Canyon with Maverick Helicopters
It was populated more than 3000 years ago and is estimated to be more than 5.000.000 years old. It's a breathtaking natural monument. If you get the chance I recommend to book a helicopter flight. It's breathtaking. Here's a short video of the flight.
Whenever I need a stronger HDR effect, I use ProHDR app [iTunes App Store Link]. It let's you fine tune the HDR effect after you took the photo.
To bring out more details in the photo I used Intensify Pro App [Homepage Link] on my Mac. As the name suggests, Intensify Pro help you to intensify your photos in various aspects. The pro version even supports layers and brusher to apply effects only to a part of a photo.
