Dieter F. Uchtdorf, second counselor in the First Presidency, and M. Russell Ballard of the Quorum of the Twelve Apostles attended the presidential inauguration of Barack Obama January 20, 2009.1
During Obama's inaugural address, photographer David Bergman created a "Gigapan image" from the north press platform. It is composed of 220 images, the final image size being 1,474 megapixels.
So the challenge is to find the apostles. I'll provide one bit of advice. It may not do to rely on the Deseret News article which stated "They were seated front and center some four-dozen rows from the presidential stage for Tuesday's inauguration and then just a couple of yards away from Obama and his contingent for Wednesday's prayer service."2 I just wasted too much time down that strange road.
The full screen version of the image is here.

Scott Taylor, "LDS leaders feel deep emotion at inauguration," Deseret News, Jan. 22, 2009.
