It is not easy to make unique and meaningful images at the GC. Sure, it is spectacular and everywhere you turn there appears to be a photo op, but most all of them look the same millions of other postcards. Because of the vast distances and typically limited spots to shoot from, many images look washed out or just common, and in trying to make a 'fine art' image we so often end up with a snapshot-like thing that was exciting to capture at the time, but is disappointing when you look at it on the computer a week later. This has been happening to me for ten years. This year, finally, I made an image there that I like, and still it is sort of common. Conditions are crucial there. I don't bother to take the camera bag outa the car if it's sunny and clear.
I'm sure there are many here who have had the opposite experience. Everyone has their own vision, desire, and standards that they want to hold.
I suggest getting up early every day and checking out all the viewpoints on whatever rim you are at. Come back again at sunset. Hike down the trails a bit for more special views and to avoid the crowds and screaming kids. Good luck during the day
