Blend Modes & Gaussian Blur: Long-Exposure Architectural Look
This is normally a technique that can take many painstaking hours to achieve, but I’ve come up with a dramatically quicker way to get that popular long-
exposure, daylight, architectural look that looks like night with a hint of light coming in. This won’t take the place of the long method that the top
architectural photography pros use, but maybe it will get you “in the ballpark” to the extent that you start to get some decent results, which will make you
want to dig in deeper and learn those advanced techniques.
Step One:
Here’s the original image, taken in London’s financial district (this shooting location is included in my online course at KelbyOne.com called, “A
Photographer’s Guide to London”—one in a series of courses on travel photography shooting locations around the world). I converted the image to black
and white (using the B&W profiles in Camera Raw—also in Lightroom). It was a gray, dreary day, so I let the sky blow out to nearly pure white, and then I
increased the Whites slider and Highlights slider in Camera Raw until it blew out to white.
