You may remember George Takei from Star Trek but now he is managing exceptionally written social media channels and has grown a massive following. How did he do it? He has mastered the art of a strong caption. His captions have a clear point of view, are littered with emojis (not a must but a great addition for many brands) and make elicit an emotional reaction, and better yet the motivation to comment and/or share with friends. This can be from a simple statement or an interesting question, as long as it’s authentic.
Professional cameras, like DSLRs, give you fine control over the manual settings of shooting video and allow you to achieve the shallow depth of field (background out of focus) that people rave about. While they're primarily used for photography, DSLRs are incredibly small, work great in low light situations, and pair with a wide range of lenses — making them perfect for video. However, DSLRs do require some training (and additional purchases) of lenses.
