Behind the Shot with Ellis Vener
The Spider

Why is it that the simplest looking photos are often the hardest to make? Consider this picture of a common Argiope aurantia or Yellow and Black Garden Spider, also sometimes called Writing Spiders. The idea came easily enough: “Look at that colorful yet scary looking big bug!’ Okay, so a spider isn’t technically an insect, it’s an arachnid. But you get the idea.

The hard part was getting the camera in the right spot down between the two Boxwood shrubs she had located her web between. To do that required using the Really Right Stuff components from my PG-02 Pro Omni-pivot package plus a few others. That’s what I like about Arca-Swiss based quick release components but especially Really Right Stuff gear: they remind me of the Erector Set kit I had as a boy.

I needed a jib to drop the camera down between the two shrubs. For the jib’s main arm I used a CB-10 and CB-18, joined together with a CB-HC1. For the “fore-arm” of the Jib, I used a PG-02 VA. The real trick was attaching the PG-02 VA to the camera bars so that could very precisely control the left to right orientation of the camera (the gimbal in the PG-02 VA was used set the pitch angle) and how close the camera was to the subject. Making the connection between the PG-02 VA and camera bar required an RRS FAS Sliding Clamp holding the Camera bar and a PCL-1 Panning clamp [recently replaced by the PC-PRO clamp]. A short MPR rail served as connector between the PG-02 VA and the PCL-1. By sliding the FAS along the camera bar I could set the camera-to-subject distance and I used the PCl-1 to set the horizontal rotation angle.

Supporting the jib was a large, heavy tripod and head combination, both designed to support really big view cameras. The tripod is the now long discontinued aluminum Gitzo 410C and the head is a panning double tilt Foba ASMIA. On top of the ASMIA’s camera platform I keep a second PCL-1.

Since the camera was going to be in a spot I could not access without disturbing the subject, I used the CamRanger system with an iPad. The Cam Ranger acts as a wireless live view screen with nearly full control over the camera’s settings, along with several other capabilities like HDR exposure bracketing, intervalometer, long exposure timer, focus peaking, and Focus stacking. As with my RRS gear I feel like the Camranger is a gadget that pays for itself every time I use it.

To light the spider, which we’d taken to calling Charlotte after the title character in E.B. White’s book, I used two LumoPro LP180 Quad-sync flashes. To trigger the lights a trio of PocketWizard MultiMAX v2 transceivers was used, one as a transmitter on the camera and one connected to each flash. For fill I rested a stiff white sheet of paper on top of the lens and taped to the PG-02 VA so it wouldn’t get blown in the web. To get a basic light level setting I read the flash output with a Sekonic L-758DR meter.

In the end I shot 27 frames over the course of about an hour. Using the feedback I was seeing on the CamRanger/ iPad combination (while the full resolution raw files stay on the in-camera media, as you shoot the CamRanger downloads JPEG “preview” images to your mobile device or desktop computer) was sending to the iPad, between each frame I’d tweak the prime focus point and exposure settings, and also change the quality of the light by moving the lights and the amount each light was putting out. The goal of deploying all this technology wasn’t to make a technically perfect image, but to make a photograph that I believe expresses Charlotte’s uncannily spooky beauty and evoke the primal fear and fascination we feel when looking at them.

    Ellis, your patience and determination really paid off. No doubt your deep experience and methodical approach were the key to producing an amazing image. Thanks so much for sharing your technique with us. Joe Sr.

  2. Ellis Vener says:

    thank you for the opportunity, Mr. Johnson.

  3. Mike Turner says:

    Spectacular shot, Ellis. The trouble you took to get it was well worth it.

      Thanks Mike!

      Sad to say that after we had a cold front and rainstorm come through early last week, Charlotte disappeared. I know she mated and laid eggs so hopefully next summer we’ll have the next brood setting up in our garden.

      It was really fascinating to watch her through the summer and early fall. From wrapping up and eating prey, to dealing with suitors, remaking her web , and dealing with rain we got a lot out of spending time and observing her.

    You might notice that the spiders legs and pedipalps (the small appendages in front of the head) are translucent. How do they move their legs then? The answer is hydraulics! The legs are not hollow they are filled with fluid according to http://www.asknature.org/strategy/d33d113f9f62c63f8f6bc6a607b03a4c

    “”A remarkable and effective hydraulic mechanism is found in the legs of spiders, which have muscles to flex the joints but none to extend them. Spiders stretch their legs by pumping fluid into them. When a spider gets ready to jump, it generates, for a fraction of a second, excess pressure of up to 60 percent of an atmosphere. The legs extend in order to accommodate more fluid.” (Tributsch 1984:59)

    “One particular hydraulic device is worth a little more attention here, partly because its existence comes as yet another surprise and partly because it achieves antagonism for contractile muscle in an unusual way. The eight legs of a spider differ little from the six of an insect, but a curious special feature of spider legs has been known for almost a century. While properly equipped with flexor muscles (ones that decrease the angle between one segment and another), they lack the antagonistic extensor muscles (ones that increase that angle toward 180 degrees). Biologists casually assumed that elasticity of the interarticular membranes provided the antagonistic force, not on the face of it an unreasonable idea. But Ellis (1944) remembered that spiders die with legs severely flexed. If elasticity did the extension, they would more likely die with legs extended or at least not so flexed–as do insects. He found that cutting off the tip of a leg prevented reextenson until the tip was resealed; and he found that mild exsanguination reduced a spider’s ability to extend any of its legs. He suggested that extension in spider legs was hydraulic, not muscular or elastic. The idea was confirmed by Parry and Brown (1959), who measured resting pressures of 6.6 kilopascals and transient pressures of up to 60 kilopascals (over half an atmosphere) in spider legs. An isolated leg could lift more weight as the pressure inside it was increased, and the spiders turned out to have a special mechanism to seal off a joint that prevented fatal depressurization when a leg was lost.” (Vogel 2003:421)”

    pretty cool image indeed, Ellis. Thanks for sharing and it would be cool to see a picture of your camera setup with the items you used to take the shot

    Wonderful information Ellis, thank you so much, jeff
