Instead of business cards, it is advisable to create a 24-page printed magazine of your photographs, which is used for promotional marketing purposes given out to clients and potential clients. You can create this magazine on MagClouds and Blurbs. But you should get potential clients’ business card in order to call them in the future and do business.
You can do-it-yourself via templates on various programs, such as Adobe Illustrator, InDesign, and Photoshop.
Adobe Photoshop is also good for editing purposes because you might later need to tweak some photographs, improve certain areas, and fix issues.
