The pilot announced Mt. Rainier on the left.I was seated by the left window.I immediately took my phone and captured 3 photos. The first photo was the closer of the two and is he default zoom for my smart phone camera. The second and third photos I took I zoomed out to get more of a wide, panoramic angle. The sun was so bright out of the window, I could not see the screen of my phone clearly and was narrowly focused on the screen just to try to get Mt. Rainier in the frame based on the dark silhouette of the mountain, which is all I could see from the phone screen. Once I captured the photos, I put away my phone. I did not see the object with my naked eye, as I was narrowly focused on the camera screen and straining to focus due to the bright sunlight.
