Many people are using newer cell phones for wedding photos. Thats okay if your not to picky. Most wedding cameras 35mm or 110, (medium format), have larger digital photo screens. A cell phone is very tiny. There is a difference in quality. Besides a Pro Photog can shoot photos, edited, color correct, cull, arrange in a book or album. Costs can vary so look around. Meet them, may not be a match. A contract is usually required. This protects you and the Photog. My first marriage. Set us up with 30 pictures in a wedding album. when we went to pay and pick it up, very nice, but 60 photos in the album. Photographer said take 30 pictures out, or the total cost is $1100 vs $550. This is one of many tricks without a contract you'll encounter.Couples get themselves in trouble without a contract. Photographer gets a deposit, maybe just starting out, business failing and they vanish. A real problem if your wedding is next week. So do your homework, and avoid cell phone photography. Good for selfes and snap shots, but your wedding?
