If you're looking for a photographer, you may be tempted to force yourself into working with the top 10 professional photographers you find. This can be a good starting place, but always be sure you do the same vetting of the top photographers you would if you were picking from the entire photographer pool.
Talk to your potential photographer and see if you connect with them. See if they understand who you are and have the ability to convey that to print. Look through their portfolio. Find out if they have created the work you want. Finally, tell them where your photographs are going to be located. Outdoors, indoors? Candid, formal? Make sure that they are comfortable delivering the exact result you want for your special occasion.
