Problem with my sister

[Eliane©]

Don't know where else to put this question, so off topic might not be the best way to go, but I think it's my safest option for not spamming this in a topic where it doesn't belong.

My sister and I went to a concert and we both used my camera to take pics, because she forgot to charge her battery and only uses the camera for recreational purposes. I do care more about photography and now there's a photo we are 'fighting' about, which I'm sure of that I took it. And I was very proud, because it was just with my little point & shoot.
But this thing disturbs the proudness a little, cause my sister claims she took it.
Is there a way to figure out who took it?
I was thinking of comparing the amount of zoom used to the angle in another pic we are sure of she took. To see in which one the singer is closer with the same amount of zoom, cause we were seated and in that part of the stage, the singer was in front of my sister.

What do you all think? Is this a way to figure it out? Or do you have other ideas?

I know this is a very weird question and I'm sure I'll never do this again. I'll just take my camera, take pics and if she didn't charge her battery or takes her camera, well that's her problem...

If you really take it to a high level, you could be dealing with forensics and post incident investigations. Studying the line of sight in relation to seating arrangements is a starting point. Make a diagram or plan of the seating arrangement and draw the line of site. The traverse angle should give you a rough indication of positions using the image as a reference. It would help also if you could post the image in question, but you don't have to.
Line of sight is the first step, if you could draw it up in a plan.

Wow, my first inclination is to say you both need to grow up a bit and stop worrying about who took a nice snapshot at a concert.


That said, if you both stayed in the same places you should be able to see the differences, but only slight from camera position.

If, by chance you know who shot during what time frame, you could match time stamps.

If you don't mind me saying, does it really matter? Are either of you planning on making money off this picture? If not just put it behind you, sisters argue all the time.

Arm wrestle, I reckon... Life's too short to worry about stuff like that - copy it, process one copy slightly different and have one each.

Surely you weren't taking turns passing the camera back and forth every single shot. Find a shot you KNOW you took or you KNOW she took, and go from there.

I'm inclined to say this is your shot either way. It was your camera, your settings, your card, your computer. The fact that she may have been the one to press the shutter at a particular moment is of little consequence.
There is some precendence for this position. In years gone by young artists would go to train with a master artist. If work was done under that artist's tutelage it was considered the work of the master even if the student did all the work. Likewise, I have been with friends who are newspaper photographers and they would occasionally hand me one of their cameras during a sporting event. At no time was I under the dellusion that I would get any credit if any of my images made it to the paper. Their camera=their picture. Now if I was Ernst Haas or Ansel Adams, I might be able to argue otherwise, but unless your sister is in their league; I say this image is all yours. She needs to get her own Camn Damera!

Haha, thanks for my morning laughter man. You can borrow my camera anytime, take as many photos as you want, and I'll happily own the rights! Just let me know.

Which is wrong.

If someone is hired to do something, and it is specifically noted, then the employer owns the certain rights that were agreed upon. However, if someone uses another's camera, the photo is owned by the photographer, not the owner of the camera.

Well, thanks everyone for their point of view.
It was a stupid argument, I know. And it's true, sisters do that all the time (also if they're both grown up ). The reason also wasn't that we want to make money of it, it's just that I care more about photography than she does and I want to learn from comments I get on my pictures. When I take the picture, I roughly know what I did to get it. If I get comments on a picture I didn't take, it's difficult to think of what to do different the next time, cause my sister just snaps away and when I ask her how she did it, it's "Uhm... I don't know anymore."
I also read a lot of articles on this website, but since I'm a beginner, I find it hard to compare the examples in the articles with my own pictures. So it's easier for me to compare the suggestions/comments I got on my previous pictures. Hopefully this makes any sense...

But now that our argument ended, I still think it's an interesting subject to try and find out who took it.
I will try the suggestion in the first post, sounds like an interesting project for a Saturday.

I do like the post processing suggestion... It's a nice idea to both give our own twist to it and keep that instead of 'fighting' over the original.
