DIY Panorama L Bracket

L Bracket

Do it Yourself L bracket for Panoramas

Shortly I will be leaving for a photo workshop in Outer Mongolia. When I first travel to a destination I have never been to before, I spend time online checking out images from other photographers in order to get some idea what to expect and to be able to plan ahead for the images I wish to capture. The first thing that occurred to me is the vast open spaces of the Gobi Desert and the Mongolian Steppes. In my mind’s eye, I pictured wide vast panoramas of the distant mountains and isolated gers (tents). In order to properly capture such images, I knew from my research I would need some kind of ‘L’ bracket and offset on my ball head.

To best record proper panoramas, the camera should rotate around the nodal (“optical center”) of the lens and not around the camera tripod mount in order to avoid parallax errors. There is a nice commercial device called the Nodal Ninja available for proper panoramas, but these commercial devices can cost up to $400 and more. I needed something that would be easy to pack and carry and affordable. So, I ended up making an ‘L’ bracket and mounted it to an Arca-Swiss style plate intended for a 600-800mm lens (about 6.5 inches long).

The Arca-Swiss plate turned out to be easy. I found someone on eBay that sells a 6.5″ Arca-Swiss style mounting bracket for about $27, shipped. That would actually work fine for shooting a panorama with the camera oriented in landscape mode, but ideally the camera should be in portrait mount. So, I would need some kind of ‘L’ bracket that would allow me to mount the camera vertically, rather than horizontally.

Doing a bit more online research, I found that I could buy an aluminum angle bracket that was 3″ x 4″ from They will cut the bracket for you and I only needed a piece that was 1.5″ wide and 1/4″ thick. The price for this piece is about $1.10, but will cost around $10.00 to ship! Please note that after I bought this size bracket I realized it will work fine for my camera without the battery grip, but is too short with the grip. has larger brackets of 6″ x 6″, but they are thicker at .375″. I decided to simply remove my battery grip for doing panoramas, but will later experiment with the 6″ x 6″ angle aluminum.

So for a cost of $38, I had the pieces I needed. The Arca-Swiss plate required no modification and could be used as is. For the aluminum angle bracket, I carefully measured two holes and drilled them out. The hole on the 3″ side would need to be tapped for a 1/4-20 thread to screw into the Arca-Swiss plate. This hole should be as close to the center of the lens as possible when the camera is mounted on the 4″ side, vertically. For the 4″ side, I needed a slightly larger hole to be drilled in order to mount the camera with a 1/4-20 screw (to mount via the tripod socket). I also realized that my Canon 5D had to be raised up on the 4″ side in order to permit my remote cables to be connected. I couldn’t turn the camera the other way around so that the connectors were at the top as the 4″ side is too short when the camera is oriented this way.

After carefully drilling the holes and tapping the hole on the 3″ side, I filed down the rough edges and then painted the L bracket flat black. Finally, I cut a piece of thin rubber and used super glue to glue it to the 4″ side to protect the base of the camera and to provide a better grip to keep the camera from rotating.

The longer Arca-Swiss plate allows the camera to be offset from the rotation point of the ball head, so that the pivot point will be around the lens and not the camera. This point will actually change with different lenses and eventually I may test and mark the Arca-Swiss plate for each of my wide lenses so that I can quickly set it up and be reasonably sure that I’m rotating around the ‘optical center’ of the lens.

Finally, all I have to do is stitch the final images together in Photoshop!

Lightworks Open Source

Video capability for professional level DSLR cameras is here to stay, so anyone wishing to get the most of that new camera should have some knowledge and ability to shoot and edit video. However, that means more expensive software such as Adobe Premiere, Apple’s Final Cut Pro or even Avid. Until now, that is.

Editshare has just released their Academy and Emmy award-winning professional-grade editor, Lightworks, into open source. That means it is free!!! Just a simple download! Lightworks is no slouch, having cut hundreds of films such as Pulp Fiction, The Departed, Centurion and Shutter Island. It includes a full feature set of editorial tools and is being used by many top Hollywood professional editors. It even has stereoscopic support and realtime effects including multiple secondary colour correctors. Lightworks has an advanced effects pipeline, utilizing the power of your GPU. And with support for up to 2K workflows with realtime effects, it is the most advanced editing application available. It even accepts Premiere plug-ins.

Head on over to LIGHTWORKS to download and try it out for yourself. Currently it is only available for Windows 32 and 64 bit systems, but support for Linux and Mac OSX is coming later in 2011.

Quick Tip – Dust to Dust!

Posted in DSLR, Photography General, technique, Video with tags , , , , , , , , on September 23, 2010 by Jim

Dust in your DSLR getting you down? Me too! I find dust especially a problem if you are using your DSLR cameras for video. Perhaps it is because a smaller portion of the sensor is being used, but I tend to see dust on video that I don’t see on the still images.

I keep the body cap on my camera when I’m traveling and not shooting. When I put a lens on, I generally toss the body cap and end lens cap back into my camera bag. How about you? Bad idea! That is a great way to pick up dust. When the body cap is placed back on the camera, there is a good possibility there is dust lurking on it just waiting to jump onto that sensor! Of course, using an air bulb to blow off the dust first is a good idea, but I also recommend taking the rear-lens cap and the body cap and join them together! Just a simple twist and it not only keeps them from bouncing around in your bag (vest, pocket, whatever!), but will help keep dust out of the inside of the caps!

PluralEyes Coming to a PC near you!

Taping training videos

Video guy - yeah, that

If you make videos, or use your DSLR to make videos, and use a separate device to record your audio, unless you are editing with Final Cut Pro on a Mac, you could go crazy trying to sync up your video and audio. I’ve been jealous of the Mac video editors for a long time, as they had some magic software called PluralEyes that would do all the syncing work for them.

Well, finally, they must heard my cries of anguish and took pity on me, because now Singular Software is releasing PluralEyes for Premiere CS4 and CS5 on the PC platform!! Also note that it is available for Sony Vegas.

Skeptic that I am, I decided to really issue PluralEyes a challenge. Even though the software is currently in beta for the PC, I shot 42 clips, no clap stick or sync marker of any kind, and the video was recorded on a Zoom H4N. I brought the whole mess back to my PC, loaded up Premiere Pro CS5, loaded up the video clips on the sequence line and below it, I loaded up the recorded audio from the Zoom. I exported the project as a FCP project file, loaded that file up into PluralEyes – left all the options at their default values, then walked away.

When I returned, PluralEyes indicated it was done. So (still a skeptic!), I loaded up my original project, then imported the new synced project that PluralEyes created – and to my utter amazement and astonishment – all clips were synced to the audio! This HAS to be magic!! Actually – I’m lying. There was one clip that didn’t sync (since there were only a couple spoken words), but they were placed next to each other on the timeline and I was easily able to sync that one. I didn’t try, but I’m sure if I had applied some of the more advanced sync options, PluralEyes would have synced that one as well. (I REALLY like the name of the sync option “Try Really Hard”!!!).

I cannot even describe how much time this is going to save me from performing a mundane task that I absolutely detested. Plus, I don’t have to urge the talent to clap their hands or mess with a clap-stick. In fact, as long as the audio recorder is running, I can start and stop the cameras as I please and PluralEyes will still synchronize them! I can even shoot with both my 5D and 7D at the same time and PluralEyes will even sync the overlaps so that I can use the multi-camera edit feature in Premiere.

Best of all – PluralEyes is currently in beta release, so Singular is offering it as a FREE beta download! If this is the beta, I can’t wait to use the final version. At a price point of only $149, I have placed it on my “Must Have” list.

Highly recommended!! to download the trial version!
