Not only in film but the uses of images online also need to be used wisely. Using other peoples images in your own work is stealing. For example as an Editor of an online magazine, we are very strict about using any photos from a secondary source eg, Google images. We use online photo banks that supply royalty- free images. Such as Wiki commons and Flickr Commons. There are also image banks for specialise images such as www.prshots.com, which supplies Fashion images to be used by journalists.
Having said all of this it is also important for me to protect my own work. When uploading any of my photography on to the Internet I always make sure I have my company logo over the images. However something I should start doing is adding, ‘Copyright © [name of artist] [date]. All rights reserved" in the caption of the image to assure full observation of my copyright. Prior to writing this I was unsure about the rules regarding the ownership of the copyright when commissioned by a company or client. From research I found, that in general, copyright will remain with the freelancer unless agreed that the Commissioner will own the copyright. They say that you should always ensure that you have a written agreement with the commissioner. This is something I haven’t thought about therefore I will definitely formally do this for my next freelance commission.
