Live Music Shoot

I enjoy shooting live music events.  It’s a technical challenge coupled with constantly changing opportunities for great photographs.  As I  noted in an earlier post, the low-light capabilities of the Canon 5D Mark II (and cameras like the Nikon D3) open whole new avenues for great candid shots in typically less than wonderful lighting conditions.

Last night I went to hear a local band, True West, perform at a pool hall in Waltham.  (The band is based in Maynard and we’re friends with the lead singer and her family).  I had asked if I could do some test shoots and received permission.  My goal was to see how the camera performed for both stills and video and it was a dry run for a Stone Mountain Live shoot coming up in February.

It’s probably not a great idea to discuss screwing up in public, but what the heck – perhaps I can help someone avoid making the same bonehead errors.  The day before the shoot I was using the camera to take some “home movies” of our grandson – so I set the camera to record video in Standard Definition (640×480).  I neglected to reset it to HD, and because using the camera isn’t exactly second nature yet, and because I was pretty much in the dark most of the time, I didn’t notice the framing window when I shot the video with the band.     This has two drawbacks: the footage is in SD which limits my testing (a minor problem), and the shots looks a bit odd because I was composing for a 16:9 aspect ratio while shooting 4:3.   D’oh!

Here’s a short compilation of some of the clips.  All were shot either handheld or with a monopod.  I brought two lenses: 24-70 f/2.8 L, and the 70-200 f/2.8 L.  The latter has image stabilization which works great for handheld video.   The camera records SD at 22Mbps and this clip was compressed to 1.5Mbps and transcoded to Flash — so there is some loss of quality, but you can get a pretty good idea of the shoot.  The stage lighting was, well, pretty much what you expect in a typical pool hall – pretty rotten.  So this was a pretty difficult challenge for video (and photography).

As you can see the lighting was brash and the colors changed every 2 seconds, literally.  This is footage more or less out of the camera (no attempts at tweaking the video itself).  These conditions didn’t make taking photographs easy either  – but that’s kind of the fun part of the exercise: turning a sow’s ear…

When faced with garish stage lighting, one option is to switch to B&W.  When you change from color to grayscale in  Lightroom a whole new set of controls becomes available that allow you to filter the light based on colors.  This, in effect, gives tonal control over where certain lights were falling while leaving others more or less alone.  The result is very powerful:

By taking color saturation out of the mix, you can create a nice image that has far better tonal balance.

Shooting into the lights is always fraught with danger, but can yield some dramatic images.  JD and the lights only created this composition for a split second twice during the entire evening.  Thank the gods for auto-focus.

Here I intentionally was playing with composition including the bright blue spot causing flare, a loss of contrast, or as a rim light.  I have a number of OK images, but this one felt the best:

When I am editing a shoot, and I’ve heard this from other photographers, some images just “jump out” at you — even though they may not be exactly what you were hoping for.  In this case I was very happy with the image of Laura Pratt belting out a song here, but something said “get rid of the color” and it worked even better.  The lighting and angle created what felt like a bit of a vignette effect so I used Lightroom’s vignette tool to enhance that feeling just a bit more.   I edited this at 1am and I’ll probably go back to in a week and decide I could tweak it a bit more, but overall I’m happy with the results of this first quick edit:

First cut of a nature video short

[vimeo]http://vimeo.com/2891277[/vimeo]

With the start of this new year I will be adding video to my web site’s portfolio galleries. This is the first cut of a planned portfolio video and I thought it would be fun to share this early draft with folks. 

The basic edits and transitions are done.  The footage is straight out of the camera and hasn’t been “graded” — the video/cinema term of fine-tuning contrast, color temperature, saturation, etc. that all digital photographs go through to reflect the feeling I want to convey.

The title of the video is “Assabet Winter Mornings” and was shot during two very cold (sub-zero for a while) mornings that we had here last week. All but one shot was from my backyard (another was from a neighbor’s yard that I hope will provide additional footage and photos in the future).

Music by Duke Levine (thanks Duke!).

Technical/Workflow Gory Details

Shot with a Canon 5D Mark II DSLR.  Lenses used: 70-200mm f/2.8 L, 24-70mm f/2.8 L, 16-35mm f/2.8 L, 500mm f/4 L.  Tripod + ball head.  (There are no camera moves in this video.)

White balance locked at 5700K. The camera doesn’t give much control on exposure, so I use exposure compensation to approximate what I’m looking for.

I didn’t use an external microphone for this video.  That’s the next step in my workflow.  So the ambient sounds (which is basically pink noise anyway)  are from the built-in mic, and happily buried under the music. 

Fine focus was typically done with the camera AF, but occasionally I would verify or fine-tune it using the 5x magnification (a technique I use regularly with my 40D camera).

The files were imported to my laptop using my custom process that renames stills and movies the way I like and sends the still images to a folder that Lightroom imports stills from and another folder for video clips.

I use the Quick Preview option in OS X Leopard to quickly review clips and toss the ones that I don’t like.  (If I was in the field and wanted to hack together a quick video I would use iMovie, which handles the footage pretty well).

Back at the office, I copy the video clips to a intermediate folder and again review the clips with Quick Preview on a big monitor.  More culling.  Candidate clips for the project are then dragged to a Compressor droplet.

I set up two droplets to transcode the H.264 files to Apple ProRes 422 HQ.  One of the droplets keeps the resolution native, while the other resizes the footage to 720p.   I figure why burn the disk space for projects that are only destined for the web — and I can recut it with full-res clips if I need to.

ProRes clips are then imported into a Final Cut Pro project.  Edit as normal.   The video above contains no grading – I plan to send the video through Color before I put the final rendering in my portfolio.

For the above clip, I ran the edited video through Compressor using an H.264 codec, at 5Mbps.  (I tried 3Mbps and it just looks horrible with all of the movement.)   Voila!

Why a new camera? Why this one?

When you read the economic headlines, the first question has a lot of weight.   Me, I’m following the sage wisdom of Brooks Jensen in the Lenswork Podcast #478 — I’m refusing to participate in the recession.  But it sure doesn’t mean that I’m ignoring it.

When I decided to make photography my full-time profession I had already committed to including video in my technology mix.  The shingle says “photography”, but I consider what I do to be “visual storytelling” and the technology to do that includes moving and still imagery.  Video is quickly becoming as pervasive as still photography and an important component in any advocacy or documentary project.

I’ve had a small video camera for a few years.  I purchased it hoping to do some video during my Wild Mustang photo shoot back in 2007.  That particular subject was far beyond the capabilities of the camera.  I quickly realized that doing video well, particularly nature video, was going to require a lot of hours of practice.

So about this time last year I purchased a Canon XH-A1 video camera.  I don’t have nearly as many hours with that camera as I should, but coming from a photography background I was struck on how difficult it was to compose scenes the way I wanted to.   I also, obviously, do a lot of nature photography and the limited focal range and depth-of-field of the video camera irked me considering the large investment of glass I have for my cameras.  Within a month or two of owning the camera I was looking at gizmos like the Redrock Micro, but that looked to be impossible to use in the field.

When Canon announced the 5D Mark II (hereafter referred to as the 5DMk2) would include HD video it seemed like a perfect fit: a full-frame, high-resolution DSLR that could also shoot video (just like my 3-year old Elph point-and-shoot … only good)  using all those lenses I’ve spent years acquiring — a solid camera that would stand up to the elements.

Then came Vincent Laforet’s Reverie short, shot entirely on the 5DMk2.  Here was a video, shot by one of the best photographers out there, and it looked pretty darn good — particularly in low light.    I talked it over with my financial advisor (Betsy) and put a deposit down for one the next day.

What works.

The 5DMk2 hits a particular sweet spot in my workflow.  I now have a camera that readily switches between very high quality stills (and with low-light performance that greatly increases the quantity and final quality of possible subjects) and can very quickly change to shoot SD or HD video.

There are three reasons why this is of value to me: 1) video allows me to capture certain types of behaviors and scenes that simply don’t work well as still images;  2) even relatively static scenics have a certain subtle verisimilitude which works better in video than stills; and 3) when I was purchasing the XH-A1 I asked about “environmental seals” on the camera and I got a puzzled look — at least the 5DMk2 can get a little damp and operate in the -40 to 100+F range.    OK, four reasons: 4) I think there is a business window of opportunity for stock video and I’d like to see if some money can be made there.

Having a separate video camera, and believe me I’ve tried, just doesn’t work.  The question was whether or not this “combination camera” would.

From a workflow perspective my answer is an emphatic “yes”.   Granted I’ve not spent months with the camera, so check back here in May to see if my opinions change – but I’m pretty confident about this.   The ease by which I was able to switch between shooting video and stills was nothing short of exhilarating: compose the shot, focus the shot, take the shot, would this make a good video?, yes?, hit the button, recompose slightly for 16:9, if the shot still works, set the exposure, and shoot (the focus is already done).  If the shot doesn’t work you’ve lost 4 seconds.

If I’m shooting primarily video, I can compose and focus scenes many times faster and more accurately than I could with the video camera.   As a still photographer I’m already used to standing on my head for odd shooting angles, so the lack of a movable view panel isn’t something I’m going to whine about.

A 7-second HD video clip roughly equates to  1 still.  Most clips are in the 7-15 second range, with some behavior clips running longer.

When I get back to the laptop, I stick the card in and my custom import workflow copies the stills to an “Inbox” folder for subsequent Lightroom processing while sending the movie clips to an “Inbin” — with all files renamed to my personal scheme.

I can review the video clips with the new “Quick Look” feature in Mac OS X Leopard: Cmd-Y on the file and it plays a large version of it.  If it was garbage, delete the file.  Bam.

If I need to put together a quick video with the clips, iMovie imports the H.264 files and you can do a simple cut.

But normally the clips come back to the office, transferred to the clip library.  Those that look to be worth using for a project are dragged to a droplet that runs Compressor, transcoding the H.264 to ProRes 422 HQ (and to 720p if I know that I’m just going to make a web video anyway and want to save some space).

Edit, grade, compress, publish…

So, what’s wrong?

I previously mentioned the Vincent Laforet Reverie video. Unfortunately, Vincent’s chosen subject inadvertently (or perhaps intentionally) made the camera’s video capability appear much better than it was — unless you were always shooting at night.   It was known that the 5DMk2’s video would not have full manual control, but I didn’t count on how fully automatic Canon made it.

From my rather limited perspective there are two significant things wrong with the Canon 5DMk2 video mode: it only shoots 30p (no 24p) and the draconian automatic exposure control.   The sad thing is that both are fixable in firmware.  The really sad thing is that they probably won’t fix either. Deep down  I’m hoping that Canon takes advantage (so to speak) of the economic slowdown and actually updates the firmware instead of spending hordes of money developing a whole new camera before the potential of the one they’ve just shipped is fully realized. 

The lack of 24p isn’t the show-stopper for me that it is for other people, but it is a powerful creative option that seems easy enough to have included (obviously there’s enough bandwidth for 30p, a 24p rate should let the camera run cooler and have better storage usage).

Many folks lament the lack of full manual control.   I do too.  But I’d be willing to make a compromise that Canon already knows how to do and is rather easy to implement control-wise: move “program shift” into the video mode.   One of Canon’s automatic still modes, “P”, tries to do the right thing, but you can rotate the shutter wheel to get different shutter/aperture options.  I’d be  happy if they would just play aperture vs. ISO against each other.   That would give me about 80% of what I need about 80% of the time.  I can play games with ND filters for the other 10-15%.

Oh, there are plenty of other annoying aspects to the video shooting mode (like it resetting the exposure compensation) and no histogram or “blinkies” during composition – but I can learn to live with those.

Bottom line: it is close to the ultimate “b-roll” camera for a photographer.   I’ve used it for nature and business shoots.  In a pinch I might use it for interviews, but I’d rather use the XH-A1, plug the mics into the XLR jacks, set my audio levels, and let the tape roll for 15+ minute interviews.  But after the interviews are done, I can shoot b-roll with the 5DMk2 about 10x faster than I could with the XH-A1 using anything from telephoto to wide-angle to macro lenses.

Did I make the right decision?  Overall, I think so.  Purchasing the first generation of any new technology (in this case a combination DSLR and HD video camera) is fraught with danger and we’re certainly bumping into some disappointing limits here and there.  (Made more disappointing as they would appear to be purely parochial marketing decisions rather than engineering or technical limitations.)   But my hunch that it fit well into my normal shooting and processing workflow has, so far, proven correct and I expect to start producing video at a much higher rate than I could with the XH-A1 alone.

What’s next: I need to come up with a good “frankenstein” rig that will take will work well in the field.  It will need to support both a regular video camera as well as DSLRs, have a place for audio levels and mics, and have a place for a fill light.   I’m also going to rig up a nice “rebel” follow-focus (at minimum to make precision rack focus moves). This will take a few months of experimentation and I’ll report on these changes as I go.

Assabet River Video – Canon 5D Mark II Test

Those who follow my occasionally-updated Twitter feed know that the long-awaited Canon 5D Mark II camera arrived here yesterday.  (It arrived at Hunt’s two days ago, but I resisted dropping everything and heading over by driving in the snow and ice…)

Several things attracted me to the 5D (one of them was NOT my bank account balance), but the most interesting feature for me was the inclusion of high-definition video into the camera.  It’s by no means perfect, but few things rarely are.  I’ll discuss the decision process in another article.

The camera came with a battery that was reading “low” when I popped it in, and I spent a couple of minutes on the drive back home getting it set up and figuring out what buttons did what.  When we arrived home I had perhaps 20 minutes of light left — but I figured I had far less battery.   Nevertheless, I put a 70-200mm f/2.8 lens on the camera, grabbed a tripod, and headed out to the river to see what I could capture.

Here’s my first video with the camera, crudely processed and edited :
