I know I am posting this inquiry a little late, but I hope someone can offer me suggestions for shooting on-location. I will be utilizing a 35mm format (Nikon F4, Nikon F90X, & Nikon D100) and will be shooting beach scenes (yes, we're warm here in Florida) & some sidewalk cafe scenes. I am aware that if I plan to use existing (ambient) light, the best times of the day are early morning and late afternoon. However, that does not necessarily suit my model's schedule. She is available between 2:00 p.m. to 4:00 p.m. I can only imagine the light will be harsh and deep shadows will result. I could use an opaque panel, reflector, or diffusion panel; however, would I not need one the size of a house (maybe I am exagerating somewhat) to block/diffuse/reflect some of that light? We could shoot in the shade, but I fail to understand the concept of fill-flash (& my photos attest to that fact). I have a Nikon SB26, so I know I can compensate for fill-flash; I just do not completely understand how. Finally, the model is semi-professional (at least 50% of her income comes from modeling), and she can be a real female dog (trying to keep this clean). She's great at posing, but does not have even the faintest understanding of light and its affect on the overall image. She thinks a flash is the answer to everything! Any suggestions of how to deal with a whiny, control freak, model (bodily harm is out of the question & somewhat unethical). Thanks in advance!
