I love using vintage lenses because they often have character. Modern lenses are often technically perfect (or close to it), but they usually lack the character that is a hallmark of analog photography—perhaps the precision engineering makes them too good. The imperfections of old glass is what gives them their unique qualities. One of those qualities is sometimes interesting lens flare. Some people love lens flare and some people hate it—if you are one of those who loves it, I discovered a trick that you might appreciate. It is simple (yet can be tricky), and you probably already have what you need to do it.
