Love all of them Frank, this is the kind of stuff I'm trying to develop and refine at the moment.
Ref:The Castle shot, I'm guessing it was shot with one portable flash (perhaps ProPhoto, Lumedyne, Quantum?) but I would love to know which modifier you used that was manageable in the Irish climate. I'd be amazed if you were able to use an Elinchrom Octa (unless it was a small one, do they make them small?). I am very keen to know what portable systems (and their modifiers, softboxes, octas etc) are actually manageable and practical in the situations we find ourselves in when on outdoor location in UK/Europe. I'm pretty sure you haven't just used the standard reflector on the light in that shot.
As I have said, this is something I'm extremely interested in at the moment and I have been using Quantum and lumedyne, this last six months or so and am keen to learn to get the most from them particularly in an outdoor location, situation (under the challengs we have with weather conditions in the UK and western (cold, windy and wet) Europe.
Again though Frank, beautiful work.
