Those are really good action shots. I still have a hard time capturing anyone/anything moving, even if the lighting is better than ideal. Always seems to turn out blurry. I often wonder what artists think as they roll into North Texas and realize how hot it can get here, especially if they're coming in from a tour stop that is in a cooler climate. I could think of worse places to perform outdoors: all of Florida, Phoenix, Houston. We're still hitting the 70's at night so that's something to be thankful for.
Thank you!
The lighting helped a lot. It's definitely hard to get good action shots, especially when you need slower shutter speeds at night, along with the concern that a fast shutter speed will be too fast for the frequency of the lighting. If the shutter speed is too slow, you can run into blurry action shots, not to mention stabilization issues (these are handheld shots taken on a body without IBIS, and a lens without IS). Also, I rely on autofocus, so I'm focusing on the performer's face and eyes most of the time; areas away from there usually tend to be blurry, especially as wider apertures narrow the depth of field... although I did get plenty of "lucky" shots.
On the note of the heat, I'm pretty sure it was in the 80s (if not 90s) during David Archuleta's performance; he took the stage at 9pm. You can definitely tell how much he (and the other performers) are sweating in some of these photos. In fact, I recall one of the audience members near me saying "Take it easy, David!"
And yes, David Archuleta had just come from a tour stop in a cooler climate; the day before his Trinity Pride performance, he performed in the rain in Providence, Rhode Island.
