Walking downtown on the last day before the big freeze and I saw these birds at twilight. Then they vanished and the light soaked in for the evening.



I have a tiny suspicion that the lens I used, the Nikon 24-85mm f3.5 to 4.5, has just a pinch of vignetting when it's used near its widest aperture..... Just a suspicion.


The race for bigger cameras. Been there, done that, redoing it.

Many of the more recent arrivals here at the Visual Science Lab like to give me advice like: Try a full frame camera! Or, You should learn how to shoot with a view camera! Or, The pros all use three fast, f2.8 zoom lenses for all their work! You might want to try out the 70-200mm!!! Or, You should get your hands on a medium format digital camera and try it out!!!

The last one is my current favorite. The implication being that we're all new at this and we're all shooting everything with Olympus, Sony, Nikon, Canon or Panasonic. It's a pretty fair assumption given the sheer numbers of bloggers and camera sites on the web. Outside of www.Luminous-Landscape.com you won't find many sites that have a depth of experience, and user/members, with experience in buying and using medium format digital cameras. The reasons are pretty simple, the MF cameras are ruinously expensive for most people and the compelling uses for them are more or less rarified in this day and age of everything going to the web.

But in my defense I think I should point out that three different companies started sending me medium format digital cameras (and attendant lenses) to test and review around 2009, and occasionally we still get the random, big-ass camera tossed over to us through the transom.

In 2009 I took possession of a Leaf Aptus a7i medium format digital camera and a 180mm f2.8 Schneider lens for the better part of two months. That camera was built like a rock but it had its own handling issues. Still, the 40 megapixel images were enormous at the time. The biggest thing from Canon back then was a whopping 16 megapixels.... I shot a bunch of portraits with the combo and I liked the way the lens rendered portrait subjects very much. But the camera was clunky to use and at around $40,000 for the camera and one lens it seemed a bit out of whack in the market of the day. A wonderful image surrounded by too many caveats. For me.

The next camera we got on long term loan was the Mamiya budget MF camera of the time with a 29 megapixel sensor. While they sent along a nice zoom I much preferred the images I got out of the camera coupled with a 150mm f3.5 manual focus lens I had for the Mamiya 645e. Was that camera any good? Well, we got a lot of images like this one....


...So I could never really complain about the image quality under good lighting. Though most of the medium format digital cameras previous to last year had issues with noise once one crested the 400 ISO mark.

But again, the camera crossed over the intersection of cost versus performance at a different quadrant of the curves than I thought was good and so, after a few months of evaluation and a nicely done review in a photography magazine distributed to other professionals, I sent the package back to the manufacturer and soldiered on with the 35mm form factor cameras I had as my regular tools. 

The next camera was a Phase One camera that boasted (yet again) 40 megapixels and a much improved interface. I wrote about it pretty extensively and used it for more portraits but it was as expensive the previous Leaf camera and, after I used it to make many images for my book on studio lighting it got packed up and sent back as well. The review for that camera got published in Studio Photographer Magazine. I didn't notice any great uptick in acquisition of the units after my review came out but I was happy to have had the opportunity to live with the camera for a couple of months.

What I discovered in almost every engagement with the three medium format cameras above and the Leica S variants I have worked with since is that the lenses are critical and that the sensors in most of the MF cameras need to be bigger. Not denser, just physically bigger from side to side and top to bottom. The thing that makes MF images look better (to my eye) is the way the lens draws on the bigger surface area of the sensor. 

I keep get lured back in. But my new search is to find ever faster lenses that are still good near wide open for the two full frame cameras I have in house. I'd love the longer lenses of MF for the same angle of view but I'm still not convinced that the small difference in overall look is worth the investment. I see these systems the way cinematographers see high end production movie cameras; they rent them when they need them and bring them back to the rental houses when they wrap. I've rented several of the cameras from several sources when I felt the need for something that looked entirely different to me and my clients, and every time I breathed a sigh of relief when I returned the gear. 

But I would like my newer readers to understand that when I make these kinds of choices for myself ( renting versus owning? Shooting everything with one system?)  I do it with the background of having actually shot with five or six different medium format camera samples over a cumulative time frame of about a year. My opinions are rarely the result of having read and then parroted back something that some else wrote on the web. I have lifted the weights of medium format and broken a sweat with the 16 bit machines. So please stop recommending that I "try" one. Believe me, I have. I just can't justify using it to shoot images for websites and I'd rather put that kind of money into a retirement account. Your mileage may vary. 

At this point I think the new flurry of high resolution Nikon, Canon and even Sony cameras are a very good and sensible compromise. 




I finished a project I was doing for myself. It's a site with 100 portraits that I like very much.

I always feel like my portfolios are jumbled and mixed. I wanted to create a site full of portraits that showed some of my range but more importantly some sort of cohesiveness. To that end I started sifting through hundreds and hundreds of portraits I've shot to find the ones that I liked to look at.

It's a good exercise and in my case it pointed out to me where I am weak and where I need more depth in the work that I share.

It's not a definitive collection. 100 images is little more than a tasting platter of the thousands of portraits I've shot. But it's fun to work toward a goal and my goal was to have this group of photographs that I could share, without reservation, with my clients from across many industries.

I'll use the gallery to create an e-mail campaign to existing clients. For many it will be a reminder while for the clients who hired me to shoot product or lifestyle, or who hired me on someone's recommendation (without seeing a portfolio or the work) it will be an opportunity to deepen their understanding of my core work.

Many, many people write comments to this blog and talk about how they can't stand to read talk about gear. Others state that the only thing that matters is the image. I could argue that our page views drop to near zero every time I show work or talk about photographs and rebound into the tens of thousands every time I write about an Olympus m4:3 camera but instead I'll just show the work and see what happens over on the sister blog site.

I hope you'll drop by and visit. The site is meant to be dynamic and you can change the way you view it by selecting from the menu across the top. I like "mosaic" for this presentation but you can customize it to work for you.

It's freezing here today. I hope you stay warm wherever you live. Kirk

Renae and I set out to make this photograph because we were experimenting with a bunch of different black and white looks for an upcoming annual report for which we were preparing. We would be photographing different business people in different locations and the two constants would be the lighting design and the chair.

When we are gearing up for a large project I tend to test out a number of different options well before the shooting dates so we know what we're aiming for at the outset.

It always seems to me that getting the relationship between the subject and the background is the hardest part of any portrait shoot. If the background is too de-focused it begins to look detached from the person; almost as if the person had been dropped into a second image of a backdrop.

The design aspect that gives me the most pleasure is the balance of lights and darks through a frame.

The final piece of the puzzle with this project was the printing and toning of the image. I used a Portragon under the enlarging lens to partially blur the corners of the image and to reduce overall contrast throughout the image. It's lost technology now (for the most part) because the Portragon depends on the optical process of enlarging to impart its look.

I marvel at how clear and uncluttered our shooting intentions were at the time and the amount of craft we tried to bring to bear...

We don't give away free samples but if a client wants to see a test we oblige. Someone wanted to know how big they could go with a D810 file. We sent them some Tiffs.




Advertising agencies are going through an interesting little adjustment right now. At least the bigger ones with national clients who are flocking back to trade shows. They're are moving from aiming all their stuff at the web to the opposite extreme: Posts and huge trade show graphics. The two common denominators are a need for lots and lots of resolution and also the need for content to be sharp. Unlike billboards posters, point of sale materials and trade show walls are all media that consumers can get right next to and put their noses on.

The top image is on of a hand full I sent to the agency. At full size it's a 215 Megabyte tiff file. The Image just below is a close up of my left eye. Seems to blow up pretty well.

The agency is mollified and we are continuing in our conversations....

Have a sharp day.
