Experimenting with variable neutral density on a very fast lens. Shooting wide open. In broad daylight.

The obligatory self-portrait.

Since I shoot a fair amount of video with the lenses I have for my Panasonic GH5 I've bought a good number of variable neutral density (VND) filters. One's options for shutter speed settings outdoors in full sun are limited if you are shooting video. Especially if you are hopeful about using faster apertures...

I'm cheap when it comes to some parts of the photographic buying frenzy. I could never bring myself to spring for +$250 for a 62mm B+W VND is I can buy one that works well from Zomei for less than $40. If there are color inconsistencies that result from using the bargain filter I haven't found them yet...

So we use the VNDs all the time in video production but I rarely read about people using them in still photography. Especially for non-technical stuff like street photography. Come to think of it I haven't used them very often for that either. This morning I decided I'd see what I was missing (if anything).

Of course, if you are using a camera that offers electronic shutter capability you may already have the ability to set very high shutter speeds in order to shoot wide or nearly wide open with fast lenses in the sun. But you might find that the freeziness of those fast shutter speeds has a different look --- and you may not like it. I wanted to work with a solution that would give me: A. Low ISO. B. f1.2 or 1.4. And shutter speeds in the range from 1/125th to 1/1,000th. 

I took along a GH5 and the Rokinon 50mm f1.2, as well as a Zomei 62mm VND. I was able to stay at f1.2, where I remained throughout the morning - with only one or two exceptions solely to get more depth of field... I would comp a subject, look at the exposure numbers in the finder and then twist the VND front ring until the shutter speed numbers dropped right into my preferred range. What I found is that the Rokinon 50mm f1.2 is better than I thought. Previous test were done as such low light levels that it was hard to separate out which weakness in technique was giving me crappy results; bad focusing, subject movement or camera shake. With daylight, faster shutter speeds and ample light with which to focus it turns out that the actual performance of the lens is quite good. 

I'm excited about the technique but the very next time I go out to do this I'm bringing along a beautiful and mysterious looking companion/model so we can make better use of the subject distance to out of focus background. It will also give me a much more interesting subject to photograph. I just need to find someone fun and relatively immune to the wretched heat. We will always be looking for open shade. Although a sweating model would be novel.... Happy to try new stuff. Nice respite from the harsh reality of real life.

Subject too far from camera to show off effect well.


The second door from the left side of frame is my target in the image just above.









Nicely sharp wide open. And look at the pavement in the background....






After a dalliance with some full frame Nikons, a joyous return to the Panasonic GH5 and the almost perfect Olympus 12-100mm lens.


Don't get me wrong. I really like all that Nikon stuff. The full frame, at 36+ megapixels makes for lush files and a fairly easy working process. Big, juicy files, laden with detail, make work at the edges of the ISO envelope a bit less of a nail biting experience. But the cameras and lenses are huge. The lenses, even the good ones, aren't perfect and the lack of an EVF means there's more screwing around to get just the right exposure. Shoot. Chimp. Shoot Again. Chimp Again. Repeat.

I was heading to the Blanton Museum on the UT Austin campus yesterday morning and I wanted to bring along a camera with less physical gravitas. I was getting tired of the bundle size, the irrefutable effects of gravity and the extra layer of work involved in using an "old tech" camera so I decided to bring along the smaller Panasonic and one lens. I looked into the m4:3 drawer in the equipment cabinet and passed over the alluring prime lenses; the single focal lengths that always promise I might get one glowing, razor sharp nugget of visual joy. I went straight to the 12-100mm; my interest in it stoked by an hour's use of it for the video project done just the day before. 

I loved the show of art from modern Australian Aboriginal artists. It's a great show and  a celebration of interesting patterns and symbols intertwined with beautiful colors and textures. When I had gone through the galleries twice, with the camera hanging over my left shoulder, I went back and walked the galleries one more time cradling the camera in my hands and shooting images of the gallery itself.

With the Olympus Pro 12-100mm I believe the system defaults to using the image stabilization in the lens. In any event it all works well to deliver a very stable and handholdable package that I can use down to something like a 10th of a second with no discernible artifacts. The lens is supremely sharp and is well corrected at most focal lengths. At 12mm there is some noticeable (but not excessive or complex) barrel distortion but it's easy enough to handle in Lightroom or Photoshop if you need perfect geometry. The thing I like about the lens is it's feeling of confidence. No matter what the subject matter, if it's in the range of 12-100 you can shoot without a neuron wasted wondering if your lens is up to the task.

This lens, in combination with the really tight and capable GH5 body is a great all around system. It's my default and my basis. While the Nikon full frame system ( or Sony or Canon ) is great for those times when you just have to have all the clutter in the background disappear courtesy of the magic of limited depth of field, in many way the smaller format is better. Easier to stabilize. Easier to ensure image quality across the frame. More physically manageable. 

In the end they are all just cameras. The show at the Blanton shows me the real nature of art work. It's the WORK. It's getting up and thinking about the work you want to create and then committing to doing it with all your attention. Making time to work is work. But doing the work is good work.

Doing it with a camera you enjoy using takes a bit more friction out of the process.

So, what's on tap for today? Well, I was the subject of a fun interview yesterday evening by Gary Friedman, I signed lots of paperwork for the sale of a house in San Antonio. I caught up on billing and client correspondence, got a bunch of video files over to the Fedex office for a client in Florida and a bit more. But over the last week I missed my traditional walk through the city of Austin with a camera and I'm afraid this weekend might be similarly tricky so I'm taking the morning off to recover, stroll with mindless (mind free? unmindful?) abandon through the familiar streets of the city and take a (metaphoric) deep breath before stumbling back into the strange world of self-employment I've constructed for myself. Some moments feel as though I am hanging by my fingertips while other moments feel like I've just walked into the most spectacular party on the planet. But I'm never sure which agenda is ascendant and which is on tap for the present.
