Pictures are also very suggestive when it comes to printed booklets. A picture is a much stronger vector of communication and it’s much easier to show people what you can do. Additionally here, the quality of the photos needs to be as high as possible. The message that a booklet transmits about a certain brand is professionalism, high quality and client-orientation. Imagine sending out this message with some poor quality photos and on a thin plain paper. It’s just not in the best interest of the company.
