I find this thread to be charming, in a naive, extremely self-centered sort of way.
Why yes, you can take photographs if you want to, as long as you can "get away with it". Whoop-dee-doo.
All THAT shows is that you place your own selfish desires above your alleged respect for the creatives involved in the theater industry.
So, make your choice, - but at least be honest about it.
If you never post or sell your photos, I suppose there's no monetary damages done. However, if you believe you have principles, then I think you all need to rethink your case that:
"well, every-buh-dee else doz it! soze it must be Oh-KAY!"
Several years ago I had an online back and forth with an apparently young B'Way fan who was thrilled to brag that her dad had burned her copies of the CDs released by various B'way singers. Back then, burning CDs was not the easiest thing in the world to do, so I guess it gave her some sort of cachet.
Anyway, I pointed out to her that on this level, every CD sold makes a difference to the performer - not only in terms of direct money to the performer but also every unit sold gives the record company more incentive to release more CDs in the same genre - etc. etc.
She refused to acknowledge that by burning copies of her favorite CDs she was disrespecting the artists that she claimed to hold in such high esteem. I called her out on that and she literally said she would have her "producer daddy" (I hope literal father, not sexual weirdness) track me down and make sure I never worked in show biz again.
Well, so far, he hasn't found me...
Bottom line -
My opinion, as a Broadway and touring vet -
Yes, when you get a BS tour from a cast, management and/or crew member, that is a special treat. My opinion is that you should respect that artists who worked very hard to create everything that you see and avoid taking photos.
If you absolutely feel that your momentary desires are so much more important than the rights of the artists you pretend to respect, at least do NOT ever post our photos - If for no other reason than whomever gave you carte blanche to try on a costume can indeed be summarily fired. As they should be.
Seriously - who ever allowed somebody else to try on a costume should be canned. No questions. I know several B'way company managers, producers and stage managers who regularly read these boards.
Above all, use discretion. I know it's tough when you're trying to be an "insider", have super secret inside connections that make you feel special - but the fact is, everyone needs to actually THINK about the consequences of their actions, and act accordingly.
