I took this photo almost four years ago. This was before my tripod days.
Since then, I have worked with a D50, D7000 and the full-frame D800. However, I am not sure what I could do differently even with the latest gear. First, the inside of the UK Pavilion was crowded, as was the entire Expo. I could not have even set-up a tripod.
Next, the inside of the pavilion was dark. Despite the aperture, I was still at ISO 1600. You don’t want to see the photo at 100%.
The most challenging part would be the exhibit itself, where all the illuminated rods are situated at different depths. A depth of field nightmare.
Every factor conspiring against a sharp, noiseless photo.
