Resort photography encompasses architecture, activities, restaurants, beaches, and more. As there are many different situations it is best to bring your full compliment of hardware and skills. Use natural lighting whenever possible, draw people into frames, and engage different disciplines of photography in order to capture the right shot.
Photographing guitars (especially acoustic) are the most challenging around light as they are typically polished. This creates pools of reflection to have to deal with. Whenever possible use natural lighting. When not available try to use soft lighting and utilize angles to prevent glare from showing in your pictures.
