If you are a casual photographer, you can take your passion anywhere, and you do not need a license to click the photos of landscapes, food items, and festivals. However, if you are running a business as a sole proprietor where you charge your clients for your professional services, you may be requiring photography licensing.
It still depends on the country you are in as most states may not require you to get a license – even if you set up a photography business. Therefore to avoid any inconvenience later, it is better to obtain information regarding and such requirements so you can carry your business without any restriction. The last thing you would want is to try to cover a client’s shoot only to be told you cannot continue as you do not have the license to take pictures.
