Input: Channing is a photo ninja.My parents told me a horror story about their friends' wedding photographer, who insisted on always getting the shot he wanted.  The end of their friends' ceremony: couple has their first kiss, crowd cheers, photographer calls a halt to their walk back up the aisle so he can get a better angle.That wasn't acceptable, and we weren't keen on having a lens constantly in our faces either.  So, one of our priorities was to find someone who could capture the day while still being unobtrusive.  Channing was perfect.  He documented all the moments we remember, as well as many that we wouldn't have seen without him.  Yet, other than when we were taking portraits, he flew under the radar, never interrupting the flow of the evening or getting in the way of our guests.And the photos!  Our gallery has over 700 images -- every one looks crisp and professional, and many are downright stunning.  He has an amazing eye for expressions: emotions and reactions come through so vividly that we feel like we're reliving parts of the celebration.  He's also willing to go the extra mile to get different perspectives.  During the first five minutes of our ceremony, he somehow managed to get across the building, up to a balcony, and back; he took beautiful photos of the unveiling and gorgeous panoramas showing all of our guests, and he returned before our officiant's welcome was over.  We got a glimpse of how he did it from a video of our recessional, in which he silently sprints along the side of the building to get both our first kiss and our walk up the aisle.  It couldn't have been more different from my parents' horror story, and we couldn't imagine better photographs.Seeing his site (http://www.channingjohnsonblog.com) is probably more convincing than reading this review.  We were swayed both by the impressive portfolio and by our first meeting with him, and we liked him so much that we decided to do an engagement session as well.  During that session, he set two nervous subjects at ease, and we ended up with a spectacular set of photos.  We gave them to our parents and grandparents at the wedding, and they were thrilled.Finally, working with Channing is a joy.  He is incredibly responsive and endlessly thoughtful, and he clearly cares about what he does.  He listened closely to all of our requests and concerns, and he dealt tactfully with a couple of our friends and family who insisted that he ought to take a particular picture in a particular way.  Our engagement and wedding photos came promptly, with the files mailed on disc and loaded on an online gallery.So yes, Channing is a ninja.  He is everywhere and seems to be nowhere; he has consummate skill in his art; he is awesome.
