Hello; i'm shooting a car interior, front two seats with two subjects during the day and wanted to know what kind of light would suffice. Obviously, there's the sun but it constantly moves throughout the day and of course, the car interior provides a lot of shadows. As we're going to be out in the field would certain battery powered LED's (within spending range -- tried the litepanel micro.. It was too weak) or flourescents be powerful enough during the day to add some consistent illumination to the face? Or, if you have a better solution please let me know. Thanks!
