The Camera+ App.

I have this new favorite app called Camera+.  It does this:

These photos were taken on my first Colorado hike in the Chautauqua Trails in Boulder.  I never knew why everyone said the air was thin here in Colorado because I've lived here my whole life.  But after living at sea level for about 3 years, I finally understand.  I couldn't make it to the top of the trail because I was so out of breath.

(This one was in Lakeside, CA)

There is one downside to downloading this app though...  I keep getting disappointed by real life because it's not as beautiful as it is in my photos.
