Many, if not all of todays brides spend a considerable amount of time looking at wedding images on Pinterest, and yes there are many beautiful and inspiring shots to be found. Pinterest is great for providing wonderful inspiration to a couple planning their wedding. It can help to generate ideas fo colors, favors, deocrations, and the overall feel for the wedding.
However, it is important to remember that the images you see on Pinterest are the best images from thousands of different weddings. The best of the best. Your wedding should not look exactly like your pinterest board although it should be inspired by it. Take the ideas you see and make them your own. Do not be afraid to just be inspired by what you see and not try and duplicate it. This is your wedding so make it your own.
This also applies to yoru photography as well. When you select your photogrpaher you do so because you like the look and overall feel of their imags. The beautiful unplanned moments that photographers capture are always the most treasured images. You can't plan for the emotions and surprise moments that happen on a wedding day. Trust your photographer to capture your day and provide you with images that others will later be inspired by on Pinterest.
