I have been asked to take picture of a barbecue grill + food but I have never done that before. It will be used in an advertisement poster. I believe the BBQ grill they are providing me tomorrow will be in a dark environment, I know I will have to bring my tripod but will I need any lightning equipment? I doubt I should use flash. Please share your past experience/ advice and example. > Using a Sony Alpha - 3.5-5.6/ 18-70mm.
