Here’s an example of how photos were used
Founded in 2001, BACtrack is the leading brand of breathalyzers offering a full range of innovative breath alcohol testers for both personal and professional use. They are the first company to ever receive U.S. Food & Drug Administration 510(k) marketing clearance to legally sell breathalyzers to consumers for personal use. BACtrack products are available in 20 countries and at over 10,000 retail store locations including Walgreens, Costco and Best Buy.
Photographing the small mouthpieces used on some breathalyzer models took some macro-photography ”field of focus“ and Photoshop focus-stack know-how. After learning techniques and investing in some equipment I was able to get just the shot I wanted though and these became useuful on a range of product marketing materials.
