With business portraits, clients generally know their audience so we can usually very quicky determine an appropriate background or setting.
Clients are provided all high resolution files, important for many business applications requiring both print and on-line publishing requirements.
For studio sessions, typically we discuss in advance the look and feel needed. The session may included a classic studio background, and sometimes an alternate look, for a different purpose,or audience. A good strategy for any session is to take care of all immediate and future image requirements.
Often it can make sense to shoot at the customer location. In addition to being convenient for clients, it can also provide opportunities for group portraits, "at work" shots. Also, it may be important to include settings and backgrounds at the company site, and even products. These environmental portraits on location can present opportunities for stand-out and unique images.
