I've been contacted by a PR agency that wants me to go and do still's and video for a press event in Amsterdam. They say that will pay for my tickets and hotel and in this case I was wondering should I charge anything for my time of traveling. I've seen some photographers are charging something like 50p per mile but I'm not sure if this is in case when they need to drive to the location and they need to cover the fuel cost etc. or it's just for their time.
Any comments and advice are appreciated.
