Creating video from motion and stills. Always having a camera around is a good start...



I haven't really discussed much about the Panasonic GH5's video performance yet, instead, I'd like to write in more general terms about how I've been using my cameras. Not just Panasonics but also Sonys. When I sit down to evaluate a camera I'm no longer looking at a camera as a "single use" device that will just deliver a great photograph. I want a camera that will hit well above the bar for image quality in still photography use but I also want a camera that will do very good 4K video. And I want to spend no more than $2,000 per camera body. My basic criteria includes: a microphone input jack, a clean HDMI output, the ability to manually control audio levels and a useful and logical menu for setting all my camera controls. It's a given that the camera will have a high enough resolution for still photography (16 megapixels, min.) as well as the ability to make RAW files and also to make pleasant Jpegs which are usable right out of the camera. 

Why the $2,000 price limit? Because I like to buy my primary cameras in pairs and doubling prices gets uncomfortable quickly. Since cameras in the ascending age of video are still changing rapidly (as far as processor speed and video features) I want to be able to switch out cameras more frequently than we used to so I can take advantage of the new tech (HDR video anyone?). 

But why this fascination with cameras that swing both ways? Some interesting studies from the advertising community are revealing. Seems 70% of internet users get their daily dose of content entirely, or almost entirely, from their phones. Additionally, while reading lots of type on a phone is a pain in the butt for most people watching short videos has become as easy as breathing. Every marketer I know is rushing to provide more and more video content for not only their websites but their YouTube channels and their many social media feeds. Just last week, at a three day corporate show for WP Engine, I was asked to make photographs as well as video. At the same show we fed a stream of images to the social media managers from the company so they could upload content from the show in progress. You may want to resist working in this new way but I'm pretty certain that clients' expectations are not going to regress back to a slower, more stationary methodology. 

What I want to write about today is how I've been using video and photographs together for my theater client, ZachTheatre.org. I've been providing them with interviews of actors, directors and choreographers for their main stage shows. The idea is to invite the online audience to look behind the scenes and get a more nuanced understanding of how live theater works. How a production comes together.

I start my process by reading about the plays or musicals the theater is producing. Once I have the story line figured out I like to go to an early rehearsal to get an idea of the director's vision. Since I'll need good b-roll for cutaways, and to spice up the interviews, I always want to go to a tech rehearsal, with actors in costume, close to the opening date. By the Sunday before a Tuesday or Wednesday opening the costumes are pretty much finished and the stage set has received its last touch ups. Without an audience in the house I can spend time finding the right angles. I'm already familiar with the pacing and action since I've been to earlier rehearsals.

There are things I know I'll want to capture and weave into our video edit. For Dancing in the Rain I knew I wanted to get good footage of our lead actor actually dancing in the rain. Just 20 or 30 seconds of him tap dancing through the onstage downpour. But I also wanted to capture video snippets of each of the other main actors in character. You never know until you've finished an interview exactly who or what the interviewee will mention!

For Singing in the Rain I wanted to interview both the director and the choreographer. I arranged through the public relations director, Nicole, to reserve the V.I.P. lounge in the main theater space. It's a great place to shoot interviews because the room is modern and neutral but also because it has an entire north-facing wall of floor-to-ceiling windows. Nice lighting if you can get it! But outside light fluctuates so I also set up a big, soft main light from the same direction to establish a base so passing clouds don't mess with my exposure on the talent.

Once I had my angles mapped out for shooting and lighting I got to work on audio. I killed the power to the bar refrigerator (too much noise) and put up a few baffles on stands to try and kill the air conditioner noise (not turn off-able, non-negotiable in parts of Texas....). Then I put up my favorite two hyper-cardioid microphones at the end of a boom pole and hung them about 18 inches from the interviewee, just above the top of the frame and angled down about 45 degrees, aimed at the talent's mouth.

Since I had the PR director assisting me on this shoot I was able to ditch the tripod and try working with the GH5 camera on a monopod instead. In concert with the image stabilization system the footage looked quite good with just enough movement to keep from looking too static. I was able to do this because I had the PR director actually asking the interview questions. 

As soon as I finished both interviews the choreographer and I headed to the stage where he demonstrated the on stage rain effect by.....tap dancing through the pouring rain. I set the camera for the stage lighting WB and exposure and then handheld about three minutes of dancing while trying different compositions and framings. 

During the tech rehearsal I mostly shot photographs but would switch the camera over to video settings if I anticipated a dance number or a comedic moment upcoming. It's a lot of extra work to make multiple trips to the theater to catch different stuff that may never make the cut but the trade off comes late at night when you are editing and you remember you have just the right three to five seconds of tight video of tap shoes splashing through stage lit puddles.

When I finish recording the videos and photos and the interviews I come back into the studio and start making little virtual stacks of content. All the interview footage goes in this folder, all the b-roll video goes into that folder. I open Lightroom and put in all the photographs and look for sequences I know I'll want to use. Since I'm heading for a video edit all the stills I decide to use get cropped to 16:9 and sized for the file type I'll be using. Since this project was going to be edited in 1080p I made the files 2198 on the long side. That gave me a little breathing room within the overall frame so I could crop in where I felt it would make the presentation stronger. 

When I finally sat down to edit I listened to both interviews a couple of times, taking notes about stuff I liked and other stuff I wanted to cut out. Then I started assembling a timeline with the good content. If I felt the interviewee's delivery was too rushed I'd look for natural pauses and drop a half second or a second of black into the gap to make a pause from one thought to the next. Of course I would need material to visually cover the pauses but that's why we shot all those photographs and b-roll to begin with, right?

Once I get everything from the interviews laid in like I want it I make a pass to see if I can cut out "ums" and "ahhhs" and distracting word fluff. It's best to really stretch your timeline way out when making these kinds of audio adjustments because it allows for exacting work. 

When the interview timeline is more or less locked I start looking for little chunks of video or photographs that correspond to what the interviewee is talking about. For example, the choreographer, when asked about his favorite scene from this production, discussed a scene with a character named, Cosmo, who does a great song and dance number. I didn't have any video of that part of the play but I was able to reach into the photography folder and pull out twenty or so images that were a close reflection of what the choreographer was discussing. With a series of fast, one second cuts the images worked perfectly to add strong visuals to the narrative.

When the director discusses the challenges of making it rain on an indoor stage I had fast paced video footage of the main character slipping and sliding and tapping across the stage in the rain. It was the perfect visual to play over the director's conversation. 

And here's the thing about having a camera that can do both parts well; if all you need to do is change to the video setting and change the shutter speed to work with your fps, then the color and tonality of the video and the stills will match and intercut with each other beautifully. While the lighting on the interviews will be different the overall feel of the files will come through as a consistent element. 

It's an intangible but I can feel the work hold together better when it all seems to come from a unified source. A matching visual style.

There's a perception that all video work gets done on a big tripod with a fluid head. That the camera needs to be nested in a collage of pre-amps, cages, monitors and geared controls. But really, when shooting live action on the stage I'm happy to have two identical cameras, set to the same WB. One with exposure set for stills, one with the exposure set for video. Each dangling on their strap just waiting for me to move from one to the other, grabbing it up, making a last adjustment and then holding it as steady as I can --- regardless of file type. As clean as making snapshots. 

Your mind changes from making one-off masterpieces to making serial frames that can work in either modality. That's the promise of a "bi-lingual" camera system.

A Gallery of Hand Held Photos Taken at Zach Theatre with the Panasonic GH5 at Rehearsal. A "real world" Test of the camera at ISO 1600. Also starring the Olympus Pro Lenses.


All the images in this gallery were taken for Zach Theatre for their current production of

We used two Panasonic GH5 cameras and two Olympus Pro series zoom lenses; the 12-100mm f4.0 and the 40-150mm f2.8. All images were shot at either ISO 800 or ISO 1600 and both 
lenses were used at their widest apertures. 

Shutter speeds ranged from 1/30th to 1/500th of a second. 

The camera was set manually and color balance set for the basic stage wash before the start of the show. Post processed in Adobe Lightroom and delivered online via Smugmug.com.

A review of the GH5 camera after 15,000 exposures under all kinds of light, and a few hours of video thrown in as well.


I'm slowing winnowing my way toward minimalist gear status, when it comes to camera equipment. Rightly or wrongly I'm making the assumption that we're moving away from the "precious item" concept of photography to a different understanding of photography altogether. A period in which the photographic and video content and style are much more important than the ultimate qualities of traditional presentation. Now, whenever I say this a big swath of people get their panties in a bunch and tell me that they practice making beautiful and majestic prints as their art and don't give a rat's ass which way the trends bend. I try to gently remind them that my blog is not entitled, "The Leisure Photographic Life of Retired and Semi-retired Old Guys from Other Professions" rather it is called the Visual Science Lab and it's very clearly about the styles, times and trends that impact current commercial image making and multi-media. If you love making 20 x 30 inch prints, with inexhaustible detail and grandeur, of the "found objects" that catch your eye then that's what you should do but, unless you are the indefatigable Peter Lik,  I can pretty much assume you won't be making a living selling them....

My kid has one more year of college that I'm paying for so I make business decisions based on trying my best to read the hieroglyphics on the internet walls and adapt my business posture to at least sustain profits. 

In my latest shift (hopefully shifting with the market) I've purchased two GH5 cameras and a smattering of really good Olympus Pro series lenses (and Panasonic/Leica lenses) and have started using this system for pretty much everything that comes into the job queue. 

I never really feel comfortable writing about cameras until I've put in at least my first 10,000 shots so I've been relatively quiet here on the blog about making GH5 pronouncements. But looking at the image count across my two cameras over the last month and a half shows me that we're closing in on the 20,000 frame mark, and that doesn't include the work

Finally, a reason to use the second memory card slot in the GH5s.

I'm photographing a three day show in downtown Austin and here's the technical ask from the client:


"We want really nice, big, juicy raw files of our speakers, the panels, the breakouts and all the rest of our corporate event stuff for the three days of the conference but we also want to be able to upload ample selections of images in almost real time in order to share them on our varied social media accounts (Facebook, Instagram, Twitter, etc.). So, we want you to also be able to deliver small (1,000 pixel) jpegs from each session to our social media guy ---- who is in another city. The best possible scenario would be to shoot a session until you know you have good stuff and then to head to the media room to upload the images while the session is still.....in session."

I read the manual for the GH5 and found that I could customize how I use the card slots. I have identical 128GB V60 cards in every SD card slot. The #1 card is set to receive raw files while the #2 card slot is set up to receive much smaller Jpegs and video files.

I pull the #2 card out of the camera once I feel a session is well covered, stick it in my laptop and upload all the new Jpeg files to a Smugmug Gallery dedicated to my client's event.

The social media guy checks the gallery for new stuff and incorporates the images into the social feed.

Finally, a rational, real world reason for the existence of dual SD card slots on modern, reliable cameras!

Redundant back up? Naw, this is not rocket surgery...

Rating the relative effectiveness of various cameras' image stabilization.

A handheld, image stabilized still shot from "Singing in the Rain." 

It's hard to make definitive statements about the effectiveness of  image stabilization across brands, models and different sizes of image sensors but...someone asked and I thought I'd give it a try. I haven't shot with all that many cameras so I'll focus on the ones I know of from experience. 

The current top dog of image stabilization, with utterly miraculous performance, is the latest Olympus EM-1 mark 2. Nothing else can touch it. Unless you are a ten cup per day coffee drinker you can pretty much ditch your tripod. This should not surprise anyone who had previously shot the EM-5 mark 2. I owned several of them and they were steady enough to use hand held when shooting video (see the Cantine video for end to end Olympus EM-5 mark 2 samples --- in motion).

The one addition that makes the EM-1.2 the best of the best is the ability of that camera system to use both the lens I.S. and the in body I.S. together. At best the system delivers 6.5 stops of stabilization. If not for the god awful menu system I might have bought that camera instead of the GH5.

The GH5 also has a dual I.S. feature and it works very, very well with a limited number of lenses from Panasonic. Using just the in body stabilization is very, very good as well. I've been using it with several Olympus zooms and several current Panasonic primes and find it to be in the same class, overall, as the Olympus EM-5.2.

The stabilization in both the RX10ii + iii, as well as the Panasonic FZ2500, is equally good. It's the latest five axis variety and since the lenses are built specifically for the body/sensor system I believe they are able to optimize their I.S. to good effect. 

As we move up the format size in cameras that use in-body image stabilization we get less and less overall effectiveness from their systems. The Sony a6500 is at least a stop or a stop and a half behind the m4:3rds cameras and the Sony A7ii and A7Rii are at least a stop worse off than the a6500. And most of the bigger cameras have yet to incorporate competitive dual body+lens I.S. systems. 

All bets are off when it comes to comparing systems that only use lens stabilization. For one thing not every lens you want to use is stabilized. But when done well the lens stabilization can be quite good. 
When I worked with Nikon I bit the bullet and bought an 18-200mm lens even though I knew it was not a spectacular performer optically. I bought it because there were situations when I really needed stabilization and would not have time to use lights or a tripod. That lens delivered a stable shooting platform and was an eye opener. Rock steady shots but humdrum optical performance. A trade off. 

Not so with the newest Panasonic and Olympus flagship systems. You get rock solid stability and great optical performance from their Pro series lenses. My least satisfying image stabilization experiences have been with cameras like the Sony a850 and a900 full frame cameras. They gave, at most two stops of stabilization (which is nothing to sneeze at compared to ancient times) but with some lenses they seemed to perform with less enthusiasm, delivering maybe a stop different at longer focal lengths. 

My (unproven) assumption is that it's all about overall sensor size, acceleration and physics. The smaller the mass you have to move and the smaller the distance you have to move it the higher the performance is going to be and the more accurate the corrections will be. 

All things being equal (but they never are) logic would suggest that one inch sensors should be the easiest to imbue with the highest stability performance followed by the m4:3rds and then the APS-C sensors and finally, in next to last place, the full frame sensor cameras. In last place would certainly be the medium format cameras whose only advantage is sensor size and, when dealing with camera motion whose biggest disadvantage is.... sensor size. 

1200+ images shot handheld with the GH5 and some Olympus Pro lenses last night show me that the system is highly competent and workable for me. If I wanted the best offered anywhere I'd be putting those Olympus lenses on the front of an EM-1.2 camera body and never look back. But I.S. is only one factor among many in the pursuit of good photography. Compromises abound. That's what makes it all so interesting.
