Things I wish I had known before the wedding session

In May 2018, I photographed a wedding for a family friend. She asked me if I want to photograph her wedding because she needed a photographer and she wanted me get experience and start a portfolio for my photography career. When I got there I talked to the preacher so I knew where he did and didn't want me to be and what he didn't want me to do. So he wanted me to take photos without the flash on. I thought I did a pretty good job. I took over 4,000 photos at the wedding and the reception. I went through the photos I took and they were fine for being a beginner but I was kind of hoping they would look more professional. The problem was I didn't know how to shoot that well without flash. Yes, I practiced without flash before the wedding but they didn't have the right lighting. I wish I would have known how to shoot in manual mode because I would gotten better photos. If I would have known how to shoot in manual mode the photos would have been more crisp and clear, not off-tinted. I also wish I would have known how to shoot moving objects, also known as sports mode. If I would have known sports mode I would have been able to get better photos of the kids dancing in the reception. Lastly, I wish I knew how to use Photoshop, so that I could have edited the photos and make them look more professional before I gave them to the newlyweds. Overall it was a great experience and learning opportunity, but I recommend that if you want to photograph a wedding for the first time, make sure you learn manual mode and practice, practice, practice.
