Image Anatomy: Eye of Cyclops

Many people have asked me about how to make star trail images in general (it’s ridiculously easy) and how exactly  ”Eye of Cyclops” was created in particular. I promised I would do so, so here is that promise kept.

I am going to keep this as short and sweet as possible, straightforward, and direct. I’m not going to dumb it down too much but at the same time, I’ll keep it from becoming too esoteric as well. Some of you will think it’s far too technical and some will think that I didn’t give enough information. That’s a guarantee. I’m just trying to strike a balance here.

First, the location is in the Alabama Hills of California at the foot of the Sierra Nevada Mountains and in the shadow of the highest peak in the continental United States, Mount Whitney. The name of this particular arch is not important, yet it should be obvious to those who know the area. There was lots of pre-planning involved in order for this to work, including a visit during daylight to acquaint myself with the location and it’s surroundings as well as devising my strategy and imagining how the final image would look later. I got a bead on the north star, Polaris, using the iPhone application, Star Chart. I wanted the concentric star circles to revolve around a point that was located inside one of the arch windows. The two arches reveal themselves to the sky when oriented toward the north, so this was easy enough. I chose the desired height of the tripod, the lens (16 mm), composition, etc.

Crappy iPhone Photo

My strategy then was as follows: when it became dark enough, I would first make one exposure while “light painting” the inside of the arch. I could do this with a 30-second exposure and a high enough ISO to adequately record light in all areas of exposed rock, even the deeper crevices. My settings for this exposure were: 30 seconds, f4, ISO 640, Manual Exposure mode. To light paint, I used my headlamp wrapped in a red bandanna. The reasons for the bandana were twofold. First, I wanted to soften the light to avoid ghastly hotspots on the rock. Second, I wanted a reddish tone to the interior of the arch and the red bandana did the trick quite nicely. I could precisely adjust the color and balance the  light and dark areas later in Photoshop, but I still wanted it as close as possible. Manual focus is also important so that the camera doesn’t start “hunting” for a focus point in the faint light. Focusing on the lip of the arch at f4 gave me all the depth of field I needed. The result of this first exposure can be seen below.

Exposure Number 1:

Then without moving or refocusing the camera, I changed the ISO from 640 to 100 and the exposure mode to “Bulb.” Ideally, I would have preferred to focus at infinity for this second exposure, but it would have created some problems later when I combined the two exposures and also I knew from experience that it wouldn’t have affected the look of the star trails too much anyway. Every other camera setting remained the same. With the Bulb setting, the shutter would remain open as long as the shutter release is being depressed, so a cable release with a locking mechanism is needed.

I then waited for the waxing crescent moon to dip over the horizon and for darkness to fall completely for the maximum number of stars to be revealed. When the time was right, I locked the shutter and left it exposed for just over an hour. The rotation of the Earth did all the work for me. I simply sat on a nearby rock, ate a sandwich and listened to some music. Beach Boys’ “Pet Sounds” if I recall. Settings: 64 minutes, f4, ISO 100, Bulb. The result you can see below.

Exposure Number 2

The result you see above has some post editing work done, mostly subjective stuff such as adjusting the white balance to make the sky a dark blue tone, increasing contrast to make the star trails more noticeable, and removing most of the color from the stars as well. As I said, these are all my personal preferences and since it’s my little slice of fantasy, I can make it whatever the hell I want it to be. So there.

Next, I blended the two exposures in Photoshop. Since there was such a clear difference in dominant color tones from one exposure to the next – blue and red – I used the red channel as a mask for the first exposure and it nearly blended itself for me. After a little touching up on the mask, a slight crop, and some noise reduction applied to the sky, the resulting image you can see below.

Eye of Cyclops

I hope you found this hastily-written post to be of some help to you. It was a very fun, rewarding image to make and I hope you like it.

If this sort of photography appeals to you, we will be doing much more of this during my Arches and Canyonlands Photo Workshop in Moab, Utah this May. Be sure to check it out.

    Most of reader will not understand how much study is needed to produce such a photograph.

    Amazing output … Thanks for knowledge sharing too :)

    “I can make it whatever the hell I want it to be. So there.” ….Several hours of serious homework (writing a paper as usual), this was a good laugh!! Additionally, Very interesting and Good insight. Think I already said it somewhere else but REALLY LIKE this!!

    Hey REAL nice work…….. :)
    Sometimes or can I say always when I shoot star trails, there are these breaks or gaps in the trails. Do you know what cause’s this?

    Pet Sounds…well well well :) If you haven’t seen Almost Famous, please rent it today.

    Rockin’ shot, Richard!!!

    Nice outcome and useful information. I will have to try it sometime.

    Fantastic Job Richard! I like the whole explanation. I have recently made a 3 hour exposure to capture the star trails in a single shot. I did not light paint the surrounding but that does give me some idea. However why did not you make only 1 shot and still red light paint the rock. the red would still have been brighter than the rock natural colour and subsequently you would have achieved the same result minus the photoshop process. Or am I wrong?
    here is the result i got with my 3 hour exposure:

      Tom, honestly, I don’t understand the question.

        Richard,

        what i meant was exactly what Ryan asked. I was only wondering why you had decided to stack 2 exposures rather than doing one during which you would have red painted the rock. But reading your answer to Ryan, it does make sense.
        Although i love Photoshop and LR4, i am always trying to think if there eis a way to minimise the post processing work. ;-)

    Sorry the link did not work. Here is the resulting image of my 3 hour exposure: http://tom-migot.artistwebsites.com/featured/the-polaris-swirl-tom-migot.html

    Why is it better to blend the images versus doing the hour long exposure and painting the rock for a minute or two here and there?

    • Posted March 1, 2012 at 8:48 pm by Richard Bernabe | Permalink

      The primary reason is the differences in ISO: 640 vs 100. At 640 ISO, the rock can easily pick up the illumination from my rather weak headlamp and it only takes 10 seconds or so to light paint. At 100 ISO, some of the hard-to-reach areas and more distant areas will be difficult to reach with the light.

    Thank you for the writeup Richard very interesting, I will have to try this one day. Love the final shot..

    Hello, thank you for this tip.
    I have a question: for the star trail you use only one long exposure, but many people for star trail stack multiple exposure (es 4minute for exposure for several time) and than combine in Ps. What is the difference and how do you calculate the time for know when the star trail is complete and press the button to stop the exposure?.
    Thank you.

    Your work is absolutely amazing. I like how you tweek the pictures to how you prefer. So true photography can become anything you want you just have to use your imagination.
