A basic set of decent interior imagery is a necessity.
There are plenty of obvious uses for exposure on- & offline.
Especially for new businesses this is the case. When your local newspaper writes an article about your grand opening, you don't want them sending a photographer. You're venue will be portraid differently every time, the quality will vary, and the photographers style might not match with your brand. The photograph could be the first contact with a potential costumer, make it stick!
Product photography is not always a must.
But if you serve food, it is without a doubt the best kind of original content you can create for your business' marketing.
For use.. everywhere.
