Just a quick post about something that's starting to become apparent to me. Camera sensors aren't necessarily getting better but something else might be...



It's been an interesting day. I've been getting e-mail comments about the flower images and graffiti images from people who want to know if I really shot them with an "old" Nikon D700. They mention how rich the colors are...

Now....I owned a D700 back when it was a "new" camera and got a lot of good use from it for several years but I never remembered it as being such a good camera. It didn't have any big flaws but the files seem humdrum. Well balanced but nothing to write home about. Nothing remarkably better (other than the full frame sensor) than the color or tonality I was getting from a D300 or a D2Xs. But here we are nearly ten years later and I'm loving the color and tonality I'm getting when I process the raw files in the latest revs of Lightroom and PhotoShop. The colors, especially, seem nearly foolproof. And they've also got character.

I know that no one went back and retrofitted all the D700s on the used market to make the hardware much, much better so I started following the chain backwards. I count well over a dozen major upgrades to the Adobe raw converters in the past decade. It's possible there have been more.

Could it be that the cameras we've been working with were packed with potentially great hardware even a decade ago but we could only unlock a small percentage of the imaging potential because the limiting factor was in the software? In camera processors were much slower and less capable ten years ago which slowed down throughput and encouraged camera makers to optimize Jpeg files for speed rather than ultimate quality. The raw converters of the day were running on older processors, supported by slow and pricy DRAM. Who doesn't remember all the third party programs like Bibble that were marketed because the camera company raw programs were so slow and doggy at the time?

Each improvement of the raw converter software on the market (Adobe+DXO+Capture One) was in part a response to bigger camera files but also faster processor speeds, higher throughput on the desktop and the need to make each successive generation of cameras appear as though they were worth the money to upgrade to.

But an rise in the software "water levels" lifts all "raw file boats" because, at their core the files are all just binary information until they are de-mosaiced and interpreted.

It's entirely possible that the files I am seeing now are not just looking better because I'm remembering the old ones incorrectly but because the newest software is able to squeeze and massage so much more from the raw information provided.

Remember when we used to see movies like "The Wizard of Oz" on broadcasted television when we were growing up? We loved seeing the movies on our old TV sets with their almost square aspect ratios and their low resolution. Except in actual theaters we had never experienced better imaging. Then TVs got bigger and the color got better and better. Finally we're at a point where we can see old classics spread across 60 and 70 inch, 4k monitors and, if the movie has been remastered (re-interpreted using the original information existing in the actual film media) we find the quality to be a good match for modern sensibilities; at least when it comes to sharpness, tone and color.

Did they go back and re-film? Heck no! They just used the latest processing to wring out some more of the potential that was in the original capture all along. Isn't that what happens when we take a raw file from an older digital camera and re-imagine it in the most contemporary and advanced raw converter software? Some things won't improve dramatically. Noise won't get that much better, but color, tonality, sharpness and anything that can be interpreted and augmented by improvements in software will benefit the older hardware and the work we create with it.

Test this out yourself. If you still have an older Canon, Nikon, Sony, etc. digital camera hanging about as a door stop, charge up the battery, pop in an old CF card, shoot a test and then open the file in the absolute latest rev of your favorite flavor of raw converter and see if the camera doesn't transcend your older appraisals of its quality.

Kinda kicking myself for not thinking more about this sooner. Thoughts? Into the comments below!

Flowers. I was interested in seeing what these flowers looked like when shot with a 50mm lens nearly wide open. I like them. You might too.


For some reason my brain grabbed hold of the idea that shooting with a Nikon D700 would be fun and, like a dog with a bone, my brain is refusing to let go of my latest fascination. It didn't help when my friend, Paul, brought a coveted 50mm lens to lunch and bequeathed it to me on an infinite loan. 

I've been having trouble getting back in the work mix since my two month daily on the job training of extended family administration started back at the end of December. I was banging my head against the desk in the office, working on some marketing, trying to move people off the idea of moving projects back a bit on the calendar. It's not that the need for cash flow is a particularly pressing issue but when some great part of your self-identity is wrapped up embracing the persona of a working photographer then not working just.....messes with your brain.

At any rate I figured I'd done enough for one day and needed a break. Something different that shuttling between house and office in an endless search for the next cup of coffee. I stood up, stretched and grabbed the Nikon D700 and the Sigma 50mm Art lens and headed out the door toward the graffiti wall and other fun parts of downtown Austin, Texas (named by U.S. News and World Reports as the best city in the United States of America in which to live --- for the second year in a row...). 

I took a different route from my favorite parking place to the graffiti wall and it took me past a lovely garden plunked down right next to the hike and bike trail that runs right through the middle of the urban concentration of high rise apartments and endless, chic, office buildings. 

It was an overcast and gloomy day and I did what all photographers probably do on days like this --- I pushed the "WB" button and set the white balance on the camera to the little clouds icon which, I'm pretty sure, means "overcast." When I saw the gardens I was immediately attracted to the red and pink blossoms waving back and forth in the breeze against their field of green. I thought that a deep depth of field would ensure that nothing stood out as special so I took the opposite tack and went for "wide open." 

I'm not sure what the "Deep Roots Garden" is all about but I can sure say that I like it. Seemed like an oasis of calm and tranquility in the middle of an indifference to organic aesthetics. 

I don't know if you'll be able to see it in the images as shown here; all compressed and mushed up on the web, but I can see all the little "hairs" and details running down the stems of the in focus flowers. My understanding? It means the lens has no front of back focus and that even wide open it is impressively sharp. 

Spring is in full bloom in Austin. Everything is green and growing. Trying to savor it all before the bleak heat waves of Summer and the arrival of the carnivorous mosquitos...

It was still nice to have a jacket with me yesterday. Hovering between comfortable and chilly.

And now the D700+Sigma 50mm Art Lens endure the dreaded graffiti wall test.


Something about gloomy days in Springtime that make me want to grab a camera and go photographing. I have a route I walk and I like it because I can do it in about an hour and a half (if I don't pause to chat too long...) and even though I've walked it for years it changes enough, week by week, to be continually interesting to me. 

On a different note: After swim practice today I decided that I needed to replace my 55mm f2.8 Micro lens because it had come down with the widely known affliction associated with this lens; the dreaded "oil on the aperture blades." The lens no longer stops down reliably and the repair folks say that the repair price isn't much less than finding a new version without the special "oil appliqué." 

I found an older 55mm f3.5 Micro Nikkor that is Ai (auto indexing = a must for use on cameras put into service since the 1970's). The focusing ring is smooth and the glass is clean. It set me back a whopping $60. The A7iii has arrived at my local dealer. I'll call and arrange a "borrow for testing" and see what Sony fixed and what they broke...

I also put my name on the waiting list for the new Black Magic 4K Pocket Camera. It's purely a video camera but it does 4k to a full on raw file (if you want to...) and has a huge screen on the back. It takes m4:3 lenses and it's reported to generate very nice video files. It's only $1295. We'll see when it gets here; Black Magic is always a bit iffy on final delivery. I have a friend who bought the original Black Magic Pocket Camera (not 4K) and he loves his. Super nice files....

If you click on these photos they will enlarge to 2199 pixels X some less amount. The look dandy on my big screen; the full res versions even more so. 









This image is not from the wall just off Lamar but is a downtown shops genteel interpretation of public art. 2nd Street.

So, whenever I get a new lens like the one a friend dropped on me last Friday (the Sigma 50mm f1.4 Art lens) I like to shoot a couple of test shots to check focus. Especially wide open...


So I leaned over from the desk and shot a quick frame of the bright metal ring towards the back of the lens. This was a good test for the accuracy of the focusing area of the sensor chosen as well as the overall accuracy of focus. No front or back focusing here at f1.4. So my next move is to focus on something at the far middle distance. In the shot below I focused on Michelle's face on the 16x20 inch print, sitting just to the left of my filing cabinet. And so far it's right on the money when used with the Nikon D700. Mark me "happy." 


The next step is to go outside and shoot some stuff at all kinds of different distances. That's up next.

The OVF versus EVF arguments are really more about nearly everyone trying to toss out multiple babies with multiple basins of bathwater...



DPReview tossed out some topical clickbait today about the death of the DSLR which was occasioned, I believe, by discussions they had with camera makers at a trade show in Japan. According the their various discussions the market for cameras seems to have reached a tipping point and the trends point to a rise in the acceptance of mirrorless cameras at the expense of traditional mirror bangers. Lots of people weighed in but most them seem side-tracked by tangential images that have little to do with the relative features and benefits of both types of cameras.

I believe that there are only two fundamental reasons why the mirror-free cameras will eventually become the more numerous and popular of the camera types and these two reasons have nothing to do with the presumptions of the general camera buyers.

First, I think the market is not driven by the camera buyers, as we often believe, but by the camera makers themselves. The camera makers, from Canon to Olympus, are ready for a wholesale change to mirrorless cameras because each camera requires many fewer parts and many less manufacturing adjustments in order to function within workable tolerances. If camera makers can maintain pricing within market segments while replacing higher cost DSLRs with lower costs mirror-free cameras they win on manufacturing savings alone. Canon and Nikon have always known this was the case but wanted to wait and see if the buying audiences could be willingly dragged in the same direction that the makers' accountant deemed more profitable.

As a sub-feature of manufacturing it is also easier to make smaller and lighter zooms and wide angle lenses if the flange to sensor distance can be reduced sharply (as in the design of most mirror-free, cameras). Being able to offer good quality (optical quality) lenses which are less costly to make (and ship) but which fulfill the same niches as more expensive to make lenses for traditional DSLR cameras is another profit plus for the makers.

There is something similar afoot in cars. Electric engines have far fewer parts than combustion engines and require orders of magnitude less maintenance as well. The result should be less manufacturing complexity and far fewer recalls and expenses. A plus for car buyers but a huge plus for car makers. (Note that the battery side of the equation is different from the issues involved in engines... don't argue the whole car...).

So, Canon and Nikon let Olympus, Panasonic and Sony work out most of the kinks of creating mirror free, interchangeable lens cameras and are now poised to step in and grab the lion's share of the profits. That's just the way it typically goes.  But it's important to understand that the simplification of the basic camera is a much bigger win for the makers than it is for the consumer who might have been quite happy with the older technologies. Mirrorless is not necessarily the way forward in cameras but probably seemed to Panasonic and Olympus, and more recently Sony, to be a way of using manufacturing costs efficiencies as a disruptor to the overall camera market. A way of dislodging the iron grip of the two comfortable leaders in the business.

The second fundamental reason people are moving from OVFs to EVFs is that being able to see in advance exactly (more or less) what you will see after you push the shutter makes iterative learning in the photographic arts much easier for people with little previous education in image making. Look at the little "TV" and turn the dials until you get exactly what you want!" Early acceptance of EVFs worked for people interested in video but at the time the video performance of mirrorless cameras was no great shakes (Panasonic GH series excepted). Perhaps that's why initial sales floundered.
Now that an EVF is for all intents and purpose the equal of the optical finders in most consumer DSLR cameras there is less and less reason for users to have a preference for traditional technologies and a somewhat more pressing case for always on live view. 

To serious amateurs and professionals the EVF offers a number of benefits but most of them are in the field of helping pre-visualize a final shot or in taking advantage of elimination mirror slap, and its attendant lowering of image sharpness, from lowering sharpness.

To hear the unwashed masses tell it these reasons are minor and the big differences between traditional cameras and the newer, mirrorless ILC cameras is all about the size and weight of the cameras. They could not be more wrong.

If that was all people cared about then mirrorless cameras would have died on the vine within a few years of their introduction into the markets, skewered on the sharpened pikes of many generations of cellphones.

Most people who buy stand alone cameras in addition to smart phones have, as their primary intent, the desire to take better images, and to take images that have characteristics that set the final images apart from what a typical user can get from a cellphone. Not just better high ISO/noise performance but also enhanced focal length ranges and better control over the results of depth of field decisions.

One can not help but notice that some popular mirrorless cameras (The Panasonic GH4, GH5, GH5S, G9, G8, the Olympus OMD EM-2 and others)  have grown in size and weight but have also grown in greater consumer acceptance during the same time frame. I also see many of the more serious mirrorless cameras, like the models I listed, being used frequently with battery grips to actually enhance the camera's handling performance by increasing its overall size. At the same time you've probably noticed that Canon and Nikon's very capable entry level DSLRs have shrunk down to the point where they compete, on physical volume, with most mirrorless offerings.

And while these smaller DSLRs are, in terms of overall image quality, very, very good you don't see many professionals and serious hobbyists rushing to dump their much bigger "professional" cameras in order to embrace the benefits of the single metric of size. Diminutive is not all it's cracked up to be.

It would be folly for camera makers to listen too earnestly to a vocal few who have determined that small size is the compelling reason for the market's embrace of mirrorless cameras. Reflexively making cameras smaller and smaller, without mindful regard for "haptics" and performance is the epitome of tossing the baby out with the bathwater.

All the Nikon and Canon have to do to overwhelm and re-dominate the market is to repudiate the trend towards tiny and instead replace expensive optical viewfinders with state of the art EVFs in the models that work well today. The Nikon D850 has been in high demand and short supply since its inception. Transition that picky market segment by creating a twin product that uses an EVF instead of a moving mirror and prism. The same across the entire line. Let buyers vote with their credit cards.
I'd vote for a D850evf over a plain D850 any day of the week.

The Canon advanced amateur line could be overhauled in the same way. In either the Nikon or the Canon camp or both they could retain their lens mounts if they wanted since it's my belief that the desire or demand to be able to use all sorts of legacy lenses is, frankly, much overblown on the web.
I'd conjecture that most users, especially in the younger audience segments, are generally less interested in using old, crusty manual focus lenses that we remember from out initiations in photography than we avid practitioners of a certain age profess to be.

A Canon 5Dmk1V or a Nikon D750, fitted with an EVF would become a better video tool, a more practical educational took and still, with PD focus on chip, be able to handle traditional DSLR strengths like continuous AF for sports.

Canon and Nikon benefit by being able to offer more things people seem to want, such as faster frame rates, more finder overlays, continuous live view while holding onto their embedded audiences by dint of those audiences' lens investments. They can attack previous mirrorless competitors head on, with the same features and performance options while still offering a vastly bigger selection of dedicated lenses which are optimized for their mount and their systems.

Canon and Nikon could also benefit by having their most advanced models available in two styles; with and without EVFs. The OVF version would become deluxe and limited edition tools of a certain percentage of users, continuing the halo effect enjoyed by both in the sports arena with very little downside.

Sure, a Sony, Olympus or Panasonic camera might let you use a Nikon 43-86mm zoom on the front of it but...would you really want to?

Nikon should have learned the hard way with their first mirrorless foray (V series) that tiny isn't necessarily the first feature most serious users demand. In fact, for sheer handling something like the Panasonic GH5 is the smallest camera that still feels reasonable comfortable and well laid out to me...

I think we're counting down the months until we see the vision laid out for us by Nikon and Canon for the replacement of their cameras in the $1000-$6000 price range. I'm hoping they don't base their market research on the whims and unicorn chases over in the forums on the world's most contentious camera website. I'd hate to see un-holdably tiny camera bodies and a raft of equally tiny and bland little lenses as the offerings for the future.

Big and bold is good. With electronic viewfinders it could be even better. And all that legacy glass....

What do you think the camera future holds? I hope I'm able to buy stuff that's big enough to wrap my hands around. I'm tired of the miniaturization compulsion disorder amongst some users. Let's not sacrifice good ergonomics just to add some mostly useless features.

Some outtakes from my Thursday portrait session with Michelle. Nikon D800e and Nikon D700.





The ones with the background light are from the D800e + 105mm f2.5 and the ones with no background light are from the D700 + 85mm f1.8.



What the hell happened to the weather? It was warm and pleasant in Austin yesterday, now looking for anti-freeze for my camera!


Studio Portrait. Wholly unrelated to this post other than 
as a continuing example of my work....

Just before I went to bed last night I took Studio Dog out into the backyard and we smelled the air and luxuriated in the warm, quiet feel of the night. When I crawled out of bed this morning there were wind gusts of 25-30 miles per hour and the temperature was a soggy, cold 43 degrees. There is still condensation on the glass panes of the front door. 

I dragged myself out of the house and over to the pool where it was still 43 degrees and, after standing on the deck marveling at our collective insanity, I plunged into the water with the rest of my aquatic crew. The water temperature was a balmy 80 degrees and we had our usual Saturday morning fun; getting in 4300 yards of good swimming. I must tell you though that getting out of the pool, with the wind and cold, was a bracing experience which motivated a fast walk to the locker rooms some hundred yards away.

When I got back home I turned on the heater, something I thought we were finished with until the Fall. 

back to photography. I was feeling a bit unmotivated to re-engage with my own photography lately. I'm sure it's a result of what has been my very divided attention. I knew that the best medicine was to shoot something I would really enjoy, with someone I would really enjoy photographing. I sent out a text to my friend, Michelle, in hopes that she would have time to come by for a portrait session. She was happy to oblige and we hit the studio on Thurs. afternoon. 

We did what we usually do when shooting for me or for Michelle; we sat in the living room of the house with Belinda and caught up. We've known Michelle for decades. She was talent for dozens of our ads and TV commercials back in the days when I was working as a creative director at an ad agency and she's been an enthusiastic fan of my portrait work since our first sitting. 

After our long conversation we headed out to the studio and got to work. I'd set up a flash with a 47 inch, deep Octabox on it and it was positioned about six to eight inches behind a 4x4 foot Chimera panel frame that was covered with a 3/4 stop silk. The silk was there just to add one more layer of diffusion to the already soft light from the box. My studio is pretty "live" when it comes to light bouncing around so I placed a 4x4 foot black panel to the opposite side to lower the shadow values. 

The main light was about 45 degrees to one side of Michelle and up high enough so that the bottom of the Chimera frame was about six inches above her chin. This ensures that the neck just under the chin falls into shadow; it's a flattering look for just about everyone. I moved Michelle in as close to the light as I could get her without the light appearing in the frame. 

I also had a gridded light aimed at the Thunder Gray background directly behind Michelle. It served as a separation light. Both lights were triggered by a radio trigger in the hot shoe of the camera(s). 

I started out photographing with the Nikon D800e and the ancient Nikon 105mm f2.5, mostly nestled in at about f4 and worked with that combination for a while. Then, because I wanted to compare files, I switched out camera bodies and started using the 105mm with the D700. Then I switched lenses and tested the waters with both the 85mm f1.8 and the 24-120mm f4.0 zoom. 

I'll post some images when I get back to work on Monday. Right now I'm too excited to sit in front of the computer to post process. I'm anxious to get out and see how the Sigma 50mm Art lens comports itself.
