Thanks for the comments all. Regarding the black and white, this was a really challenging shot to convert. There's a real mix of artificial lighting under the canopy and natural light outside. When I decomposed to RGB channels to see which to mix in the channel mixer I found wildly different light and dark areas in each channel.
In the end I went for a mix of the lowest noise channels along with the one that had less highlight blowout in the artificial light globes.
