Alistair, thanks for the tip will try it
Yeocsa, 1. It also happened on the
Opera House picture at 5 sec though that may be due to other reasons. Will try a much shorter exposure as the 12-24 does not need too small an aperture for great depth of field
2. F18 was not much better. I am actually trying to avoid too bright highlights. 3. I agree with you, I think especially the
Opera House could be sharper. Even though I have a Gitzo, RRs have a delay on heads, so this was taken with a $60 Velbon not even extended at all. It felt loose. By comparison, at the long lens workshop, I felt I could have done chin ups from Birddog's Gitzo/RRS combo. Thanks for your suggestions.
Killa, spot on. I went down to take the coloured ball (it has been blue and red since my return) but alas it is no more
Oneputt, good idea, will try it
