With photographers starting out, I don’t think a professional website tells me much. I can often get a better sense of how a photographer thinks by scrolling through their mass of Instagram posts...currently it's the only way I spot new photographers...and a great way to stay up to date on...projects and new work.
Regardless of how you choose to use your Instagram feed, as a photographer one thing remains the same. Your work. In my opinion it should reflect and define who you are a creative because the reality is that it's usually the first point of entry anyone tends to have when it comes to stumbling upon your work. I personally pay a lot of attention to what I publish to a point where I keep a private account in which I publish photos with the intention to get a visual sense of what my Instagram looks like prior to publishing on my main account.
My specialty revolves around lifestyle, active and travel work and so it's with great deliberation that I blend all of them together while still always keeping a creative mind open as to where a random interest may take me because in the end you never know who may be looking, especially photo editors.
