I like lens flare. It is one of the many types of “distraction” you can add to a photo. Shooting a subject through obstructions is a great way of making the photo more interesting, “layering” the elements between your lens and the subject.
While allowing these interferences to be captured in photos, typically to also help frame the photo, lens flare can add a layer of mystery or dreaminess. It’s very cool for portraits that seem “summery” or warm or playful. Also can leave part of the scene up to the imagination.
Whatever the case, flare and excessive light are something to play with when possible! Check out some tips here.
