I am doing a fashion shoot inside a train museum, all the trains are located indoor, and the museum is lit with indoor tungsten lighting. I need to make it feel and look that the trains are outdoor, how to do I light and expose this so it looks like outdoor natural light. In some scenes I might also have to superimpose a sky in place of the overhead ceilings. My equipment will be a D7000, and I haven't decided on what lights to take with me yet, just bear in mind I'm by myself, so I can't take a whole bunch of gears with me. Please suggest.
