A version of this post appears today on Shutter Sisters.
It's probably obvious to most people who know me well (virtually or in the flesh) that I am a creature of the night. This is partly due to necessity; I work full-time 30 miles from home in a corporate office setting, and therefore, especially during the winter, my daylight hours of freedom are quite limited. Fortunately, I live in a big city that stays brightly lit long after the sun has gone down, and since I've always been a night owl, I have no problem claiming the title of streetlight photographer.
I've done quite a bit of night photography on the streets around Chicago these past couple winter months, so I created a set of Adobe Lightroom Develop Presets specifically for processing photos that were taken under streetlights or other kinds of orange-ish (tungsten) artificial dim lighting. To see larger photos of these examples, you can go to this gallery of images and click on any thumbnail on that page to see a larger version. To download a zip file of these presets, click here. You can view instructions on installing presets here.
These presets will not impact exposure and brighness, so you'll want to adjust those setting either before or after applying the presets to get the results you want. Also, since these are specifically for night-time shots that may have required a high ISO, the noise reduction settings will not be impacted by the presets, as you will want to adjust those yourself depending on your personal tolerance for noise. And while these presets were developed for RAW (uncompressed) files, most of them should work for JPEG files as well; you'll just need to tweak a little more here and there.
