I like the purple haze shot. How many exposures did you have to go through before you timed it right, Les? (I think I took a dozen or so) Or did you do the sensible thing - and time it?!
And (for Mike) I think the blacks that should be, are. Too much black can do the 'white sky' thing. But, that's only my opinion.
It was a difficult one (purple haze), took about the same amount expoures as yourself, but I noticed that the fountains changed regularly so I tried (and mostly failed) to time my shots to get both sets of fountains exposed, this was the only one I managed
