Hi, new here. Hope you veterans can help advise. I am an iPhoneographer; I take photos with my iPhone4 camera and then manipulate them using various Apps. (You can see my work on Flickr under the name AlyZen Moonshadow). I was advised by several friends to put a small signature on all my images, to protect them from being used illegally. So now my images have "(c) AlyZen Moonshadow" on the bottom right or left of the image. Several of my iPhone Art images are being exhibited at a gallery in the US. There are 40 iPhoneographers being featured, on 40 iPad screens as an installation. Now the Gallery has asked me to remove my copyright signature from my images, saying it's a collective exhibition and therefore signatures are not allowed? (This was not mentioned in their Call for Artists, BTW). What should my response be? Should I stick to my guns, or should I give them my unsigned images? Help, please!
