Through the welding glass
The other day our very own morozgrafix shared some amazing long-exposure shots taken in the Bay Area. Immediately, we wanted to know more about how he achieved these nearly magical colors. It turned out he used a simple, easily reproducible technique: Instead of an ND filter, he put welding glass (which comes in a variety of tints) in front of his lens while shooting, making it possible to take the shot in broad daylight.
Above is only a small selection of the many great shots you have taken using the technique. If you want to give it a try, the Welding mask glass filter group and the pictures’ description provide a great wealth of tips and recommendations, as well as details on the glass color used.
