These are all very usefull information and ideas people!!! I am sure that combinations of these ideas can be done as well...
I was thinking of a frozen sea scapeland... i plan on freezing actual water in my freezer and then setting a background in my bathtab and begin my project....
Experimentation is needed though.....
I also thought of gathering all the parts i need for the project and setting up everything by my parents country house near the seaside.... I'll also be needing undewater scenes, thus getting a plexiglass box, sunking it into the seawater and shooting any photos with the camera inside the plexiglass....
