Hello everyone, I need to purchase or rent some lighting equipment for an upcoming shoot and need some help in deciding what I should get. I currently only have a Canon 430 EX on my 20D and will need to shoot some close-ups and macros of high-tech computer mainframes, circuit boards, nodes, etc. for a distributor. The images will be used for a mural in their showroom as well as promotional stuff i.e. website, catalogue, etc. Think Dell catalogue for instance. I am thinking I may need a more than a macro flash. Something to give me a more ambient light without th harsh shadows and glare of direct lights. Thanks for the help.
