Thanks guys, the last was my favourite too. Interesting the suggestions to trim the top, it's been an occasionally theme with people's comments on my shots over the years. Normally I ignore it (
) but I could actually see a pano crop (top and bottom trimmed into 16:9) working alright for this one after having a quick tinker. I had left this one framed more loosely to add that feeling of stillness or "quiet" to the image, but it still retains the majority of that when cropped.
I generally struggle with different crops as they often just looked unbalanced to me. I (and I suspect most of us) would semi-conciously compose for the camera's native format, and I know I personally struggle to un-see how I've already seen (or presented) an image. I'm not a huge fan of panoramic formats overall, so I guess I tend not to think about it as much as I should on such occasions. Cheers lads, something to ponder.
