Flipping the argument. Sports Photographers can now eliminate a major DLSR camera flaw...

(I write this somewhat tongue in cheek. Try not to get too bent out of shape if you are in the wrong camp...).

"I'm sure I would have been a sports photographer and, perhaps a very good one, but I just couldn't bear to grapple with one of the significant shortcomings of the modern DSLR. I'm sure you've experienced it if you've tried tracking a football player with a mirror-encumbered camera. Or perhaps you've lived with the mechanical menace of the DSLR when trying to keep a fast runner well composed.... We all know what the Achille's Heel of generations and generations of DSLR camera is but for some reason we've all chosen to ignore it, or to sweep it under the carpet and make our excuses. 

It's the dreaded MIRROR BLACK OUT. Each time we actuate the shutter the mirror leaps up (alarmingly) and blocks our view of the image we are so intent on capturing. Visualus Interruptus.
The image is there, in front of our eye, and then it's gone and replaced with a visual fluttering of blackness, accompanied by some raucous noise and then a decidedly unsettling vibration. Thwack! Bam! Kapow! Oh sure, it's only a few (or a dozen or a hundred) milliseconds but it interrupts our continuous observation of the objects of our (momentary) desire. The faster the frame rate the longer the overall percentage of time blacked out. The slower the shutter speed the longer the overall percentage of time blacked out. 

It's been there since we gave up our Leica rangefinders in order to use longer telephoto lenses. It's always been a grave compromise as well as a source of indiscreet noise and interrupted concentration. And anyone who ever shot with a Pentax 6x7 camera (the most egregious of the breed) probably deserves restitution for partial hearing loss from the loud shutter/mirror cacophony and for the sheer amount of time spent waiting for the massive mirror to rise and then smash itself back down again. 

I can hear the cheers already from legions of sports photographers, who felt they had no choice but to use Canon 1D series cameras and Nikon Fsomething cameras to capture sports photographs, as the new Sony a9 makes it initial appearance on the market. Imagine, at speeds above 1/125th of a second (the general realm of sports shooters) there is absolutely NO FINDER BLACK OUT AT ALL. NONE. Even at 20 frames per second. 

The EVF shows the image continuously, refreshing the finder image 60 times per second (about twice the speed of human perception). Never again will these beleaguered pros face the humiliation of finder blackout. Never again will they feel the ravaging vibration of the slamming mirror assembly thrashing around in their hands. And, if they choose, then never again will they spook a golfer or diver with their klaxon-like shutter noise. In one low key product introduction Sony has saved the hordes of sports shooters from their own self-inflicted mechanical hell. Oh happy days. "

Ah, but just now I am learning that the new a9 is too small and light to be a serious professional sports shooting tool. Too many chiropractors would be forced out of business...

A Good, Old Fashion, Event Assignment Updated with a Modern Camera.


After having to wade through all the nonsense about my latest fascination with video I thought I'd give my readers a break and write about a more traditional photographic function = shooting an event for a conventional client. With a photography camera and even a flash!!!

I've shot events many, many times over the last few decades. I started out shooting events at conferences and galas in hotel ballrooms with a Hasselblad 500 C/M camera, a trusty 80mm lens and a big-ass, potato masher flash, complete with a lead-acid battery pack that must have weighed ten pounds and a lot of shoe leather zooming. Over the ensuing years the camera and flash have changed but very little else about events has. 

Yesterday evening saw me covering a corporate event for a non-profit. They were having a poster sale as a fund raiser at a trendy new venue on Congress Ave. Right in the middle of downtown, just a block or two from the state capitol building. The invitation list included a motley mix of attorneys, advertising agency people and, or course, artists. Mostly the artists who did the commissioned posters and their friends. In all about 350 people showed up to see the art, buy the art, and support my client. 
The event was beautifully done, with open bars and

Preliminary Thoughts about The Newly Announced Sony A9 Camera.

Lou. Studio. One frame at a Time.

When I read about new cameras I  usually get caught up in the excitement about all the new features. 

I wonder what I could do with a camera that could shoot 200 images in a row at
20 frames per second.  Then I wonder which unfortunate photographer  will be required to sit down and edit through 200 nearly identical images in the search for one that may (or may not) have all the right stuff. 

I read about auto focusing sensors that range, densely, almost to the edge of the sensor  and I imagine what it  would be like to just point the camera at a scene and let it decide just where that point of sharpness needed to live. 

I 've been using  cameras with many focusing  points for many years and  I usually disagree with my camera when it decides to pick a point for me. That's why my cameras and I have agreed to mostly stick to using the center AF frame. It's a simple solution but in a way it's very elegant in that I rarely have issues getting important stuff in focus. And I rarely spend time looking at useless frames filled with perfectly sharp backgrounds and oozy foreground subjects. 

I certainly can't fault a camera for having a very high resolution EVF that also refreshes fast enough to seem....seamless. Nothing wrong with that  and certainly something I would like to have on all my cameras. I also like the idea of more external switches; like the little dial that surrounds the dial to the upper leftmost control  as I  hold the camera. I let's me choose the focusing mode. Will I use manual focus? Will I use continuous auto focus? It's easier now to go in either direction because I won't have to dive into the menus and scout around for the right column to find the switch.

Will I enjoy my new found freedom and become empowered by having a battery with twice the mph? Yes, but I'll miss the uniform battery size (and type of battery charger) across the whole Sony camera product line that I own. I'm not a manic shooter so I'm pretty happy glancing, from time to time, at the battery life indicator in the existing cameras and then pulling a battery out of my pocket , as required. Comforting too, to know that I can pull batteries from one camera and put them in another in those moments where necessity steps in and demands a quick solution. 

Who is the new Sony a9 really for? Is it aimed at a portrait shooter like myself? Is it aimed at the casual user who likes to range across cities and look for magic compositions in everyday life? I just don't think so. I'm presuming that this is really a "halo" product that won't sell in great numbers but will start to cement Sony's position in the professional camera neighborhood. By price point and spec it's obviously aimed at sports photographers and ...... well..... sports photographers. I may shoot a swim meet from time to time but I'm quick enough to catch the photos at the point of high action and not nearly patient enough to wade through tens of thousands of images taken in hopes that superior numbers will yield the frame I want. 

The one area of interest for me is video, but even there I don't see any real improvements over what is currently available in the Sony line up. The a6500 also samples the full 6k frame and beautifully downsamples to 4K and other than that and a new finder there isn't much to lure videographers in....especially at such an ambitious price point. 
Perhaps if they'd done one or two more things to the body video would be a consideration but I looked with distress at that same small and fragile micro-HDMI port and just shook my head. 
The Panasonic GH5 might not be having  the smoothest intro right  now (hello focus issues) but it's set the bar for video interfaces just by including a full size HDMI port under the flap. 

For the kind of work I do....that most of us do....I just can't see much advantage over the A7Rii. But the camera I am waiting for from Sony would be the replacement to the A7ii. And all I'd really like to see is 4K video (internal) and the option for a silent shutter. Not to much to ask and I have a piggy bank with about $1995 sitting on the floor next to my desk, just waiting. 

The Sony announcement of the a9 is exciting and fun. The camera looks really good. I'd do an even trade for my A7Rii in a heartbeat. But only because I like that 24 megapixel resolution region. It's nice to make files that don't clog up the processing pipeline or make me a prime customer for Western Digital or Seagate.

If you are a Sony shooter you'll have to make up your own mind. It's a shiny new toy. But is it "my" shiny new toy?

An interview with Michael Rader, the director of ZACH Theatre's, "Lady Day at Emerson's Bar & Grill"


Michael Rader directs "Lady Day at Emerson's Bar & Grill" at ZACH Theatre from Kirk Tuck on Vimeo.

Please click through to Vimeo to see the video in a higher quality format.

This is my second video for the show at ZACH Theatre. The first was the interview of Chanel that I put up earlier this week. This video is an interview with the play's director. The same hardware was used to produce it.

I shot with the Panasonic fz2500 in the 4K mode and edited on a 1080p timeline in Final Cut Pro X. The lighting was a combination of LED panels from Aputure; both the Amaran and the LightStorm lines. The audio was recorded with an Aputure Diety microphone (and I was delighted with the sound on Michael's interview...).

While some of the still images may look familiar I tried my best to find photographs that I had not used before.

The extensive crew for this production consisted of: me.

The Sucky Thing About Video is Sharing.


I worked hard to get my video to look just right on my precisely calibrated monitor the other day and once I had it just the way I wanted it I rendered it and uploaded it to Vimeo. My client got a clean H.264 file and uploaded that one to YouTube. Oh Dear God! How depressing. While the Vimeo version looked crappy compared to what I was seeing on my monitor the YouTube version was even worse. All the shadows looked muddy and the fine detail had just vanished. I thought I was looking at SD video on a CRT. I guess that if one wants to see their video displayed the way it was intended you just have to bite the bullet and host it on your own server. Which would be a recipe for financial disaster; depending on how many loyal viewers you have looking at your work.

I've gotten into a horrible cycle of uploading to Vimeo and they, after the file is processed on their site, going to review it there and then come back and make changes to every clip (color, contrast, density) and then render and upload again. It's a time consuming process. 

On another note, the Panasonic fz2500 still has a few glitches when it comes to stably keeping the AF sensor where I want it; even with the touch screen turned off, but it's rare enough that I consider the camera usable and have gotten some really great images from it. Where it shines is in shooting video.

Personal note: If I seem a bit removed from the blog this week it's probably because my son is doing a semester abroad at a university in Seoul, S. Korea and the war posturing of the U.S. and N. Korea is a bit unsettling for an already anxious parent. Seems things are quieting down now and I'll focus a bit more on the writing and photography. I'll take that bottle of Xanax back off the desk.....


These images were all done handheld, at ISO 800 and 1600 with the Panasonic fz2500. I like them a  lot.

I think I've got the focusing/sharpness issue with the Panasonic fz2500 under control.


I initially had many photos that weren't quite sharp enough when I viewed them at larger sizes. I shot with the camera at a technical rehearsal at Zach Theatre, a few weeks ago, and found that with manual focusing and pin point focusing I was able to get a high percent of medium and long focal length shots in perfect focus. Count the eyelashes focus. 

Since then I've been trying to fine tune my camera settings in order to get highly repeatable results. Today was my day to mess with noise reduction settings. I shot raw and used the Standard profile as my base. I went into the profile parameters and turned the noise control all the way down. I boosted contrast by one notch and then I spent the day shooting. I am using the pin point focus setting with the sensor in the middle selected. I also have the focusing speed set to one notch down.

I spent a couple hours walking around town, shooting everything at ISO 125 and I am happy to report that every frame was perfectly focused and convincingly sharp. No misfires and no misplaced measurements. Now I am happy with the camera as a photography tool. I'm already very happy with it as a 4K video camera. It's nearly perfect in that use. 

The images of the old Cadillac are from the Rainey Street neighborhood. The votive candles are from Mexicarte and the deck plate live somewhere on West Fifth St. All the files sharpen up well and there's very little noise to be seen in spite of the minimal noise reduction setting.
