Creating Elliptical Star Paths in Adobe Lightroom – Part 1

Terlingua Cemetery Monument

There are several techniques used to create this image, including a method of creating elliptical star paths that is easily accomplished from within Adobe Lightroom. I will walk you through the steps I used to create the image, leaving the elliptical star paths for last.

Initial test shot

This is the initial test shot taken of the cemetery entrance monument. I used this shot to confirm sharp focus and to verify that the composition was what I desired. The hand held lighting was used here simply to aid in focusing the monument in the dark, especially helpful as this image was taken on a moonless night. Once focus and composition were confirmed, it was time to begin light painting the monument.

First layer of light painting

This first light painting exposure was used to create the overall color I wanted to impart to the photograph. This was illuminated using a hand-held LED flashligt with the addition of a red gel held in front of the light. The light was cast from the side, giving some dimension and texture to the monument. The side lighting helps prevent the flat, one-dimensional look that front lighting usually creates. The interior of the monument was lit with a small tea lamp. Because of the side lighting, you will notice a distracting shadow being cast on the right side of the alcove above.

Fill lighting layer

I took another exposure, this time using my hand-held light as a fill-light to paint away the shadow on the right of the alcove. I was not concerned about over-exposing the alcove in this shot, because I was only going to be using the portion of this exposure that filled in the harsh shadow on the right side of the alcove.

To recap, to this point I had three exposures, one test shot, one light-painted exposure, and one fill-light exposure. Now I needed to burn in some star circles.

Star circle layer

This is the exposure that was used to capture the star circles. This was a 1 hr@ISO200 exposure, which was enough time to capture star circles of the length I desired. There is no “right” or “wrong” length to star circles – whatever length works for your own artistic sensibilities is the length to use.

Now that I had captured all of the data out in the field that would be necessary to produce the final image, it was time to get creative in front of the computer.  The first step was to stack all of the source images as layers in Photoshop. The second step was to blend my light-painted layers with the star-circle layer until I achieved the lighting I desired in the final image The third step is where the novel technique used to create elliptical star paths occurs.

Lightroom Lens Corrections

The magic occurs by simply instructing Adobe Lightroom to apply a Lens Correction Profile it has no business using (under normal circumstances). In the case of this image, the lens actually used to record the images was a Rokinon 24mm f1.4. I experimented with various lens profiles, and settled on using the lens profile for a Nikon-Nikor 16mm Fisheye.  You can see from the screen capture above, the application of this (incorrect) lens profile created distortion in the star paths – exactly the effect I wanted – with just 1 click!!!

Now I finished the image by cropping the image to a pleasing dimension, touching up some hot pixels, and ended by performing some color corrections.

This is the final image, after cropping, blending, and color corrections. Notice that I chose to alter the color temperature of the sky from what I originally captured on location. Some viewers will like the color of the sky, some will not. Do what pleases you – you are the creative artist. Odds are, if you like the results, your audience most likely will also!

Microsoft Surface Studio – Abundant Potential with a Beautiful Design

 

Microsoft will begin shipping the new Surface Studio computer in early 2017. From what I see in the promotional materials and specifications, this could well be a game changer for photographic editing, particularly if Adobe gets on board by tweaking it’s editing lineup to take advantage of the surface disk that Microsoft offers.

This is one gorgeously designed piece of hardware, something that you could easily imagine Apple having concocted.  One key to the success of the Surface Studio will be Microsoft’s commitment to evolving this product over time to meet the needs of graphic artists and photographers. If Microsoft takes this seriously, they could well replace Apple as the hardware of choice for graphic artists, as Apple seems to be much more focused on smartphones and music sales than computers these days.

Microsoft has posted an informational page on the Surface Studio here, with specifications, features, and pre-ordering available.

Hello World….Again (for the third time)

Times change, interests change, and life circumstances change over time. It has been several years since selling La Esperanza, and during that time this Ranch Ramblins blog has been sitting idle.

This post marks the relaunch of this blog, with the new name of Night Sky Ramblins. The focus will be all things pertaining to night photography, including sharing of my images, equipment and software insights, and experiences that arise in my quest for the ultimate night photograph.

I thought about deleting all of my old Ranch Ramblins posts from the blog, but nostalgic impulses took over. The posts from Ranch Ramblins represent reflections from about 6 years of my life. Rather than purging them from the new Night Sky Ramblins, I’ve decided to retain them. After all, no one is forcing visitors to read old posts, and who knows- at some time in the future I might want to relaunch one more time, perhaps as Assisted Living Ramblins, but hopefully not Nursing Home Grumblings!

Any comments you may have are always welcome (except for politics – apparently that is what Facebook is for). I don’t want to do politics here, OK? Thanks for cooperating :)
