I was at a friends wedding and I was taking pictures while a photographer was there. I uploaded my pictures and put my own edit on them. Now she is asking me for credit for the pose and styling. Do I have to? Or not?
I'm not a lawyer, but it seems unlikely that the photographer has a strong legal claim in the absence of special circumstances — just like the bride's hairdresser probably also can't demand credit. However, some of those circumstances may be part of the photographer's contract with your friend, and you may be placing your friend in awkward position by (even unknowingly) breaking them.
That said, this is a perfectly reasonable request as a matter of courtesy, never mind the law. Those things — posing and styling — do take skill, talent, effort. It doesn't take much to add credit to a caption, and maybe a link to the photographer's website.
So let's take a look at some stories from Uncle Bob and Susan, some totally unrelated fictional characters, to illustrate some common things, that also got mentioned in the comments.
Uncle Bob in Paris
Last year Uncle Bob visited Paris. He also climbed to the top of the Eiffel Tower (kind of mandatory if you are there) It's about 300m tall. He tried to save a few bucks by taking the stairs to the first platform. Uncle Bob isn't in his 20s anymore, but he made it. It was a relieve that the rest of the way up can only be made via escalator.
Later, back on the ground, after sunset the Tower was illuminated beautifully. Uncle Bob sure took a photo of that. Because he made the ascend himself, he realised that it was a bit of work to climb up there and install several hundred light bulbs, connected with cables and all. It was understandable that he had to give credit to the artist of the illumination if he wanted to share his image. You actually need permission to do so.
Susan's endeavour in wedding photography
Susan tries to make a living with photography. She started to work as a wedding photographer. To build her portfolio and win new clients she asks people to give credit to her and gives a little discount on her rates. She takes lessons in how to work with people, pose them in front of the camera and make them smile in the right moment. The psychological aspects of photography.
The aftermath of the wedding: Susan
Susan worked hard to get the pictures that the client wants. The stylist she hired did an awesome job and the lessons she took in how to pose people really paid of in some great image of the couple. There were a lot of people at the wedding. among them was Uncle Bob, who also took images with his camera. A few days after the wedding, Uncle Bob posts his images from the wedding. Everybody likes them. They do get a lot of exposure, but lack any credit to Susan. that's not what Susan had in mind when trying to make more people aware of her business. She writes an email to Uncle Bob...
The aftermath of the wedding: Uncle Bob
The wedding was great. Everybody had fun. The couple looked amazing. It was a bit hard for Uncle Bob to get some images, because there was this "professional" photographer bit.. lady. She made a big fuzz about how to pose the couple. But Uncle Bob managed to snap some nice moments, too. He edited them to his liking and shared them with the other guests. He opens his email program to find...
What the problem is
Uncle Bob does not want to give credit for his photo to somebody else. He would be photographing the couple no matter if they were styled or not. But he doesn't realise that styling and pose are part of the image. Back in Paris, he took that Image of the Eiffel Tower because of the lighting. It's not like he would call the officials (he has some relationships) to turn the lighting off, so he could take an image of the Tower that he could share without the permission. He was aware of that work, because he climbed the tower before. But he didn't do the styling or posing at the wedding, he merely pushed the button. Why should he give credit?
Susan didn't think this through entirely. She cannot force other guests of the wedding to give credit to her, but sure enough, they enjoy taking pictures of what partly is her work.
Switching back to regular answer mode, this is related to the question.
How to solve this
Do you know the implications of asking for your rights? Is this a legal matter already? Do you have to fend yourself? You only really need this juristic information for a fight, be it in court or outside of it. Is the photographer threatening you?
From your question, all I can see is that she is asking you. She's not suing you. She's not asking you to take the photos down. I don't really understand what the problem is. You could simply give her the credit that she is asking for. How about something like this as an image description?
Oh, look at those two! Are they looking happy together or what? Thanks to [link to photographer's website] for that funny pose as well. What a great wedding.
After all, it is called social media for a reason. Insisting on rights and legal aspects of something is not necessarily very social. I mean what do you do if somebody in the bus asks you for your seat? Do you think about if there's a way they could enforce it by law or if you have the constitutional right to stay on that seat? (I'm exaggerating to make the point clear)
I'm not saying either one of you is right or wrong. I just wonder if you can't figure out a solution by talking to each other.
Uncle Bob goes to a movie theater. And take a video footage of the movie...
The only diference of this situation and the one you are describing is that you did not took the pictures of the photographer's cameras screen.
Probably this is not a matter of legal jurisdiccion. It is a matter of ethics.
