I think someone answered this far more eloquently already but it is stock and meant to be useful rather than a piece of art on it's own. However I will tell you that taking it was kind of unnerving and very very warm.
It's a resource, not under "photography" it's meant to be used as reference. It's actually quite difficult to understand light sources from behind / underneath like hot coals, so this is pretty useful for someone learning to draw or paint fire.
I think that's a personal opinion of yours. I admire photographers who aren't afraid to get dirty for their shots. But, like I said this is stock. If you want to see my art photography feel free to drop by my art account.
