Ah, yes, I remember this one. This was during the Great Flood of 2015 in Fort Worth, Texas. Sadly, this building is only a memory now. I still grieve the loss of Swift...
Anyways, I had no idea this thread/photo was even here until just now, but I bet I can check the EXIF data and share it for some specifics (after I find the original...).
I
think this photo mostly unedited, but it's really large and hard to see the overall photo (changing the size to a "big" medium or even a "small" large prior to sharing on the flickr site will make it easier to see, fyi). I'm pretty sure I posted one edited and one unedited, but don't remember which one this is.
Either way, the lighting was all done at the time of shooting. I'm still fairly new to light painting and was really new at it when I took this shot. I honestly can't even remember if I had colored gels yet or if I just used my trip-colored flashlight with a long exposure. I know I used the flash light and I know I used a separate red light in hopes of separating the colors. This one was slightly tricky because of the city lights that started to bleed into the shot with the 30 second or so exposure.
Sorry I'm being a little bit vague, but it's been a couple years!
Here is what I do know:
It was taken with a Canon T4i (cropped DSLR)
I strategically placed at least one, probably 2-3 separate, colored lights outside of the frame. One of these lights was a red bicycle brake light that I still have and this kind of light is the easiest to find, besides a normal white light. The other one is a hunting light that I bought from Bass Pro that has the blue, red, and green options in addition to the normal white light.
The rest of the details of this photo I'm not 100% sure about, so I'll hold off.
I will see if I can hunt down the EXIF data after dinner. I know I have some alternate versions that probably were never published that I'm happy to post when I find them too, if interested.
And, thank you, I'm flattered you found the photo so interesting!
