I happen to think that what we did on Saturday was worth top dollars.
For everybody's edification, the room we used ws made available to us by a friend who runs a spiritual healing center, and this room was a paret of that facility. The room is normally rented out on a commercial basis, but because our event was free to our members, I was asked whether the participants were prepared to consider a donation to the centre.
I indicated my belief that this would not be an impediment from our perspective, and those who attended were most generous in their donations, which Christina has thanked me for.
Ok ... back on topic!
Vince, I would think that, if you believe that the work is typical of what you are able to produce, then I would have no issues with including it in my portfolio.
I think that may be the crux of this question: are you ordinarily capable of producing similar images? If the work is representative of what you produce, then I think that regardless of the source, it's ok to include it in your portfolio.
But if it is not representative of your work, then you will have an issue at some future point when it comes to you having to reproduce that style of work.
Let me try to put this in a different way. Clearly, some of who were there on Saturday have some lighting equipment that helps us to produce the sorts of outcomes that we're seeing from Saturday's shoot. Further, nothing that I showed was particularly complex or difficult. Anyone who was there should be able to easily produce similar results now that they have seen how this can be done.
And hiring the gear to help them achieve the outcome remains a valid option too, doesn't it?
Getting back to your question, if what you're doing at a major event demonstration is something you're able to easily replicate, then I don't think I'd have an issue with including this work within my portfolio.
