I got into a debate just recently with my upcoming wedding photographer. I asked if I could have a small handful of RAW files and they politely but firmly refused - stating they are the owners and it is their creative vision that makes the photo. HOWEVER, my fiance and I have chosen the time of day, the location, the venue, the clothing, hairstyling, makeup, props etc...in essence a huge proportion of the creative element that will go into each photo. I also plan on processing those RAWs myself - a further large creative input. Granted there is still a lot of creative scope on the part of the photographer but it felt kind of weird to be told that the photographer owns the RAW pictures of me and my partner and can use it anyway they see fit, citing the creative angle. I dont know how you measure who put more creativity into the photo but it isnt clear cut from my perspective.
