The publishing industry has struggled with the rise of the internet, except for the cookbook market. Sales of physical cookbooks have remained strong, likely due to people cooking more at home during economic downturns. While ebooks and tablets are popular, physical cookbooks remain practical for cooking as they can be written and marked in. Food photography is in demand to illustrate cookbooks, with the key skills being portraits, architectural shots, and still life photos. Aspiring food photographers should build a portfolio, search freelance boards, research publishers, seek out restaurants and bakeries for shoots, and enter competitions.
