Why I shelled out good cash for yet another new camera. Or, make the cameras fit the job...


Cameras are always in flux here. We find something we like and exploit it. A few months later a different kind of project comes up and we change gears. This is not the domain of a hobbyist photographer who is hellbent on mastering one camera and one small set of lenses and then pressing it into service for everything. We tackle a wide range of projects and if a new or different camera makes the job easier, better (or more fun) we more often than not opt for the new camera.

Near the end of the fourth quarter of last year I joined an art director from Austin on one of those delightful nonstop Southwest Airlines flights to Newark, N.J.  We were going to a small town in central N.J. where we would set up lights and make environmental portraits with shallow depth of field. I packed a couple of full frame Nikon cameras and a good selection of lenses; short, fast telephotos and some all purpose zooms. You never know when a different visual opportunity might present itself...

At the last minute I also packed in a Panasonic fz 1000 camera and a few extra batteries. All of the cameras, lenses and batteries got wedged into a Think Tank Airport Security roller case while the five light stands three umbrellas, four battery powered flashes and my tripod got snugged into a padded, Tenba rolling stand case. It was heavy. But when you need stands and a tripod you've got to have them.

One the first day and a half we got all of our narrow depth of field portraits done and we were a half day ahead of schedule. A perfect time to go into the factory/facility and shoot production shots and images of workers and their machines. This wasn't on our original purview but it sure was a lot of fun. I decided to press the Panasonic into service and got many great shots that would have taken more time and been more difficult to take with the full frame Nikons. The extra depth of field worked in this photojournalistic style undertaking, as did the wildly far ranging zoom lens, wedded to a very effective image stabilization system. But the star of the show were the handful of 4K video snippets (b-roll?) that we shot on a lark.

At that point the client was hooked. The small, fast camera did such a good job generating video files that the art director called again a few weeks back and outlined a different project for the same client. This time we would go up to shoot more manufacturing images and a lot more video. Could I bring along a wireless microphone and perhaps we'd get some interviews??? Of course.

By this time I'd gotten a Sony RX10ii and, with the headphone jack and richer selection of video tools in the camera, it seemed the logical choice for this new project. I also planned on packing the RX10 classic body as a back-up. You know, just in case. We couldn't really do much lighting on the shop floors so I was pretty excited by the prospect of not having to haul around the Tenba case full of stands and flashes and I was happy that ditching the Nikon stuff was going to save me ten pounds or so in my carry on.

But then, as in all things advertising, the other shoe dropped. The art director called. There had been a rash of new hires at the corporation we'd be shooting at. Could we add a day and also get some more of those keen, narrow depth of field environmental portrait shots. When a really good clients asks the gestalt reaction is: "Yes, of course."

But here's the deal... I had my head wrapped around those Sony RX10s and I wanted to go that way. I'm just smart enough to know though that the look of the files would be different enough to be a deal killer as far as the narrow depth of field portraits went. Just too big a difference between the smaller sensor and the full frame ones. The Nikon 135mm f2.0 is just a different animal.

But then I saw the announcement and the hoopla for the a6300. If I put the right selection of lenses in front of that camera I could match the look of bigger cameras, or at least get into the reasonable ballpark. How about the Nikon 105mm 2.5? Or the 85mm 1.8? Or (fill in the blank). With the a6300 I would have a small and light body with a killer sensor and, with a small selection of Nikon ais lenses, or even an older Leica 90mm f2.0 Summicron, I'd have a combination that would give me the same look.

The added benefit would be the fact that all three cameras used the same batteries. That meant bringing along just one system of batteries and chargers. Even better, all the menus matched up well and would help me to streamline my thought processes. Seemed eminently logical to me.

The cost of the camera is just about half of my day rate so I figured with three days on site and a couple of (less expensive) travel days, I would hardly notice the impact on my wallet. We haven't finalized dates for the job yet but in the short time I've had the camera (since Friday) I've already shot a profitable job with it.

The camera packs a lot of good imaging potential into a small space but really, it had me when I looked at the new EVF. The EVF is one of the most effective ways to streamline image production that's been introduced since we started shooting digital. You don't have to believe it. But innovation sure works for me.

My new favorite combination for just walking around? That would be the a6000 coupled with a Pen F manual focus 38mm f1.8. Just right. The focus peaking in camera makes it almost perfect...

So. I bought a new video camera. It also does stills. It's the Sony a6300. I shot some casual test video today in full sun. Go see it.

I just got the a6300 on Friday and wanted to see what the 4K video was all about. I shot some sample footage in direct, full sun. I graded it quickly in FCPX and uploaded as 1080.

If you want to see a high res version of this go to vimeo and see it there. You are limited here to 800 px wide but there you can see it in 1920 px.

This is my first time to play with S-Log 2 and 4K together. I'm still in the early part of the learning curve but the ability to hold both highlights and shadows on the canoes is pretty impressive to me.

The a6300 is too small but the EVF is great and it shoots really good stills and video. Short wish list? Headphone jack. Long wish list? Taller body and a better manual.

I've shot 2,000 frames with the camera so far and twenty or thirty short segments of video. So far, so good. More to come.

Disclosure: bought with Kirk's cash. No Sony sponsorship whatsoever. Early days with the camera. More to come as I get used to holding it. The camera it most reminds me of? The Leica/Minolta CL.

Optimizing the shooting performance of your one inch camera (or any camera).


A reader has asked me several times to talk about how to get good results out of the one inch cameras we been talking about for the last few years. Let's get one thing out of the way upfront: If you need to have noiseless, ultra detailed shots at ISOs above 800 you'll likely be happier with the latest generation of full frame or, at least, APS-C sensor cameras.  Physics is physics. I guess. There are compromises in every choice we make and as much as I wish my $1,000 cameras could do ultra clean files at 6400 I am reminded that even my $3200 Nikon with a $1,000 lens isn't noise free at those settings.... You are always trading sheer quality for flexibility, handling and purchase price. 

But with that said the secret to loving the results from any camera come from using it to its fullest potential. To do that you need to practice good photography. It's that simple. Let's start with camera movement. While I.S. is magical, and both the fz 1000 and the Sony rx10 have very good built in I.S. it's not really a panacea for good camera handling and immobilization. I don't trust I.S. nearly as much as I trust a good tripod or a well implemented monopod. Step one to getting landscape photographs that rival photographs from much bigger cameras is to stop screwing around with hand holding and get your gear on some sticks. Tripods are the gold standard and I guess that's why I have a half dozen scattered around the studio and in the car. Get good ones. Get a very expensive carbon fiber model if you have to carry it a long way. Get a heavy, heavy, sturdy one for the studio. 

Use your tripod correctly. Don't depend on extending the center column to get more reach. Use the tripod legs instead. And buy a tripod that goes as high as you need it to without extending the center column. Sturdy as it may be it's less sturdy than depending on the intersection of the top plate and the legs. Once you have your camera mounted on a tripod it's kind of stupid to trigger the shutter with your finger, because that also causes camera motion which is immediately translated into less sharp images. Use a remote trigger or download the maker's app and trigger the camera with your phone. If you don't have those options then for goodness sake, take advantage of the camera's self timer to trigger a hands-free exposure. 

If you need the mobility and are still willing to give up the pure goodness of your tripod consider using a monopod. See the image above? I was about to shoot a dance rehearsal and I needed to be able to move around quickly --- but I wanted to get really sharp images --- so I put my camera on a monopod and that actually gets me into a pretty solid space. In addition, you can use I.S. on a monopod (but generally not recommended for use on a tripod) and that gets you even better results --- as long as you consider your technique. Your feet should be spread shoulder width apart and your legs and the monopod should form a tripod of sorts. Don't drink a lot of coffee or contemplate your audit while shooting and try to use a light touch with the shutter button. 

The next thing to consider is shutter speed. Most people think that stopping down to just the right f-stop is the magic way to get sharpness but that's only true if you have already conquered camera motion. You might think that, because you have miracle I.S. you can shoot at 1/15th, 1/30th or even 1/125th with the longer focal lengths of the zooms on the one inch cameras but I'm here to tell you that you probably should revert to the old rule of thumb and still shoot at a shutter speed that is at least the reciprocal of the lens length. If the lens is extended to the equivalent of a 400mm you should make 1/400th your minimum shutter speed. Even on a tripod it can make a difference if the camera itself causes some of its own movement (shutter shock, mirror slap). So, optimum shutter speed counts for a lot. Really. Always faster if you can. Always. 

So, if you've done all that stuff above you get to the idea of the optimum aperture. Smaller sensor cameras are at their best nearer wide open and further from all the way stopped down. The fz 1000 and the RX10 both love being shot at f5.6 and f8.0. They hate smaller apertures. I think of these cameras as having only three apertures: wide open, only for when I can't do anything else, f5.6 when I don't need endless depth of field but want high sharpness on a singular object, and f8.0 when I want high sharpness coupled with deeper depth of field. Wide open is only for low light when it can be used to avoid subject motion. 

So, now you are on a stout, Gitzo five series tripod. You have your aperture set at f8.0 and you are triggering with a remote or using the self timer. You found a great shutter speed.  Good for you. You are about half way there to sharpness. 

Since you are shooting landscapes the only subject motion you need to care about is trees swaying in the wind and grass blowing in the breeze. Go back up and experiment to find the shutter speed that effectively freezes this movement as well. It's trial and error but you can see the effect. And when you look for the effect on that back panel LCD be sure to zoom all the way in so you have a fighting chance of seeing the actual effect. Everything looks sharp on a tiny screen. 

The next thing to consider is your ISO. If you are shooting stuff that doesn't move you are crazy not to be shooting at the lowest, non-gimmick, ISO on offer. For the two cameras we're talking about ISO 100 is a safe bet. Only go up if it's impossible to use that optimum aperture ---- but before you bitch and moan about the need to use high ISOs just remember the generations of photographers who were able to make incredible images on ISO 64 and ISO 100 slide film. If they could do it with primitive materials you should be able to do better (technically) with the latest tech. The tripod is a wonderful camera equalizer....if you use it. 

All this preparation is for nothing if you don't get two things right: focus and exposure. As you under expose digital images get noisier and noisier. The noise obscures detail. It's like sprinkling sand over the top of a painting. You need to nail exposure. Not to, much, and not even a half stop too little. Oh sure, you can recover a lot from underexposed images but that's not the point. You asked about optimizing sharpness not compromising sharpness. Learn to read a meter and learn to effectively read your histograms and, if the subject is important to you then by all means, bracket the exposures in one third stop increments. Oh hell, do that anyway so you can bring your files back and look at them big on the screen and better see the differences I'm talking about between frames. 

Once you've absolutely nailed exposure turn your focus to focus. Most people get it wrong. Or sloppy. Or they depend on depth of field to save them. In all images only one thin plane can truly be in totally sharp focus. Everything else is a regression from the perfect focus point. It only makes sense then to nail focus precisely on what you are most interested in seeing clearly. All the new cameras have a million focusing points and ten different ways to set up focus but if you are shooting landscapes you don't need to worry about any of that crap. Set the center point as your focusing element. Set the camera to AF-S, point your camera at the thing you most want to be in focus and initiate focus by pushing the shutter button half way down. When the camera finishes its job and the point is in focus lock it there. AF-L is the setting you are looking for. Can't find it? Then once you have the point nailed switch the camera from AF to MF, effectively locking in your focus point. Recompose and shoot your photograph. Then check (review) at 100% to make sure you got focus exactly where you intended and not in front of behind or side to side. If you want to take it up a notch then go into MF and enable your focus peaking. Set it at the lowest level possible ---- it may be harder to see the little yellow lines creep in effectively but that setting has the most discrimination. Now bracket your focusing in tiny increments around the point that your camera originally suggested. 

When using the center AF sensor make sure you use the camera setting to reduce the effective sensor size to a minimum, this will ensure that you are focusing on precisely what is covered by the green indicator in the finder and not on a bunch of stuff in the periphery. 

Now we're closing in on good technique. Be sure to shoot raw and, if you have the option, choose uncompressed raw and choose the highest bit rate your camera is capable of. Usually 14 instead of 12, though you can't really do that with the two cameras we are talking about --- just set them for raw. 

That's the first half. Now you need to process correctly. Not every raw converter handles every raw file well. Sony files are pretty good in Adobe Camera Raw but the Panasonic files are better in Capture One. If you are using the fz 1000 and want perfection in your files you should be using the latest rev of Capture One. Or DXO. Correct color balance first and then exposure, if you do these steps backwards you'll find that changing color balance will change exposure. And you want optimum exposure for high sharpness. If you have the option to select a profile for the lens you use then do it because some smart people spent a lot of time learning which settings make each lens look good. 

When you have finished doing all the stuff you want to do for your file then do the sharpening last. Sharpening is an art and most people do it wrong. Small radius with big effect works better that the other way around. But be aware that the sharpness you require is not universal to everything but is dependent on your intended output. Every sensor and every lens and every scene requires its own sharpening settings. You can also sharpen in DXO, which is very good. Most people overdo which makes images look crisp until they are enlarged past a certain point --- then the look falls apart. 

This is a matter of personal taste and must be learned by first reading every tutorial the software makers offer and none that you came across on DP Review. The makers of the software have a vested interest in helping to make your work look good so you'll buy the next rev of their product. The people on DP Review are generally just engaged in a pissing contest. 

Now, there are plenty of other things to think about. Highly collimated light sources make subjects look sharper. Softer, more diffuse lighting has the opposite effect. Flash helps to freeze both subject and camera movement and so is valuable in making images that present a high appearance of sharpness and detail. 

One last thing to mention is noise reduction. Anything that reduces noise also reduces sharpness. No free lunch. Turn off sharpening in camera and apply sharpening in post production where you have a lot more control over every frame. Add just barely enough to do the job but don't be afraid to leave in some residual noise because many times it conveys a greater impression of sharpness than the noise filter does in making things ultimately seem less noisy. But the secret to taming most noise goes right back to the top of the article = shoot at the lowest ISO. Get your exposure right in camera. 

This is just some of the stuff we think about when we shoot with any camera but I pay closer attention to all of the parameters if I am looking for optimum results from small sensor cameras like the one inch or the m4:3 cameras. Practice good technical and you'll get the absolute best out of your camera.

A well done small file can beat a sloppy D810, handheld file pretty much every day of the week. As long as you aren't pushing everything toward the ragged edge of Ming's envelope. 

Does that help?
carefully handheld fz 1000





Same applies to both cameras. 

Flash freezes motion. fz 1000.

I worked late last night photographing the new play about Ann Richards that's opening at Zach Theatre this week. Usually I can post fun images from the play the day after I shoot them but this production is different and my public relations manager asked me not to post images until after they are approved by the production company. I started to post one image from last night and quickly removed it when I got the e-mail from P.R.  Too bad, because I wanted to show off the capabilities of the new Sony a6300 as I experienced them on a real job.

Instead, I thought I'd go straight to the original source and show a photograph I did of the real Gov. Ann Richards, right in front of the Texas Capitol, holding a bouquet of yellow roses.

I'll share the production photos from the play when we get the green light.

Hope your week is off to a great start.

Kirk

By the way, the play should be a great experience, especially for people who were active in Austin and Texas politics in the early 1990's. What a time!

Additional edit at 4:04pm. I dug around and found the original, full frame version of the above image and I like it even better than the cropped one. Here it is:

Shooting product in the studio with a small sensor camera. What the heck?


I enjoy shooting products in my little studio. I've got a shooting table that's just the right size and a crazy range of lights so I can customize my lighting based on the subjects at hand. Recently I had an assignment to shoot this product for the manufacturer. They went on to use the photographs for trade show graphics and general marketing, and public relations. 

The product is fairly small, as you can see by the size of the back panel connectors. When the product first came through the door I took a few test shots with the Nikon D810 and a macro lens but the process was kludgy and the depth of field issues were annoying. Now, I am sure I could have extended the depth of field to cover what needed to be covered if I had done some accurate focus stacking but that takes time when shooting and even more time in post production. I had another idea. I would photograph the products with a smaller sensor camera and take advantage of the increased depth of field. 

The first time I photographed the product I used the Olympus OMD EM-5ii camera and various lenses. The images were very good and were quickly approved by the client but in several instances, while shooting, I found myself wishing
