I spotted this Snipe at the edge of a large pool, it's a busy image but this was the clearest shot I could get at the time. I used the 2x converter, I am not a fan I think I may have gotten a better result with the additional MC14 instead. I suspect you may think the image is too warm/yellow, this was the ambient lighting.
