Abstracts



Had an hour before supper so headed out with the D800E and 180 Sigma macro IS (on tripod and IS off). I did find that with the D800E, one must check the magnified focus in all four corners as well as centre else a sig. number of shots will be out of focus somewhere due to lack of parallelism. Of course, focus blending covers that if one has the whole range covered but there are times I didn't think I should need to.

Lenses For The D800E

So, before even purchasing the D800E, I gave considerable thought to the lenses that would work with such a high resolution camera. I was quite prepared to buy nothing but Zeiss glass, manual focus, no zooms.

For reference, I used The Digital Picture and the ISO 12233 crops which I think have been an extremely useful resource. I also used the information on the D800 from Lens Rentals.

The recent articles from DXOMark on lenses for the D800 were also useful.

Photozone was of some use but consideration had to be made as to what camera the lenses were tested on - anything less than the D3x was pretty useless.

The 85 f1.4G was widely considered the sharpest lens available for the D800E, so even though I had little use for such a fast, large and heavy lens, I elected to start with that. Soon the reviews on the faboulous Sigma 35 mm. 1.4 came out and so I picked that lens up. Knowing my most frequently used lens on the Canon was my 70-200 f4 L lens, I decided to try the equivalent Nikon lens, with the idea that if it didn't pan out, I'd return it.

Initial impressions were that it didn't come close to the 85 anywhere in the image - not a big surprise, though at distance and 200 mm. it seemed quite capable - not what some reviews suggested and not what the digital picture website suggested.

I finally did some real photography and was horrified to find the entire shoot was so poor as to be unuseable even at 13X19 - so was this me, or was it the 70-200 Nikkor?

I staged a test on a brick wall at about 8 feet away, simulating the relatively close work I had been doing - could it be that the lens was crap close up while good at distance?

Very interesting. I had also picked up the 200 f4 micro nikkor. It's hard to focus because even the slightest turn of the barrel makes a big diff. in focus distance, but none the less, it had tested well for me at this distance so it was going to be the comparison lens.

I'm not going to show huge crops, but what I found was that the 70-200 was sharper and had more contrast in the centre - though the 200 was not far behind and totally useable. The micro nikkor was a little soft in one corner but not the other three, while the 70-200 was quite confusing - focus seemed to move away so that instead of the brick surface being sharp (that's what I'd focussed on) the mortar was sharper in places. Elsewhere everything was a bit blurred, while further out it would get sharper again.

I take this as a sign that Nikon have attempted to flatten the plane of focus but now instead of a simple curve flattened out, it is a complex curve - rather like the attempts to make lines straight in a wide angle lens by introducing mustache type curves.

My next experiment is to repeat the test, using something smaller than f8 so that hopefully the whole subject will be included in the plane of focus. The obvious question will be whether diffraction will become enough of a problem that it undoes any benefit of the greater depth of field.

My own experience with diffraction is that it does respond to some degree to deconvolution sharpening, to a certain point - ie. f 16 can be rescued in some lenses but not f22, and definitely not in all lenses.

The 35 and 85 are as good as the glowing recommendations. Composition is extremely important to me and framing the image exactly so vital, and that makes a zoom very handy - and in some situations irreplaceable - eg. standing on a ridge - or at roadside rather than down in the ditch to get distance right. It's fine to say you can move your feet, but that assumes a flat subject and level ground between you and the subject - and that's often not the case in the work I do. If I can work around the limitations of the 70-200, it could well be worth using, and I'll consider returning the micro nikkor (I know that my Canon 70-200 f4LIS lens is superb close up and with extension tube - haven't tested the Nikkor that way yet, but I will.

Eventually I want to round out my lenses with an extreme wide angle. I figure that with extreme wide angles, it is much easier to move to and fro to frame correctly since even a few inches of movement makes a big difference when the subject is close (almost always). I might well go right from 35 to the 14-24, or even just the Zeiss 15.

The other issue I have to decide on is what to do with my Canon gear - knowing that sooner or later Canon will do their own high res body (though they still haven't equaled the D3x that came out, what three years ago). The 24Ts-e is fine for shifting, but a nightmare to focus accurately when tilting - just not sharp enough for accurate focusing when open, and not a lot better when stopped down and therefore not nearly as useful as I'd hoped. The 17-40 won't be suitable with a higher res camera, the 90 tse will probably be ok, not sure about the 70-200 f4LIS, and my 24-70 has already been superseded.

Well, That Was A Long Break...

Not long after my November 10 blog entry, my father, age 90; fell coming out of the shower and couldn't get up. In his wisdom, he had taken his waterproof alarm off and laid it where he couldn't reach it and spent some 30 hours on the floor before staff at the lodge noticed he wasn't at dinner and came to check on him.

He was rallying quite well when he developed aspiration pneumonia and basically gave up. I think he realized he wasn't going to regain his indepenence.

Anyway, I spent much of November and December in Edmonton at the hospital and he died January 1. It's really only this last week or so that I am feeling better and at least a little ambitious.

Almost no photography has been done during this time but this week, fed up with being unable to supply clients with large prints, I finally picked up that D800E I'd been considering, and have been having some fun with it this weekend.

My arthritis is still limiting my walking so I picked up some peppers to photograph - hardly original but also challenging. Tomorrow I get brave and cut them open to see what can be made of the interiors.

I have the sigma 35 f1.4, Nikkor 85 1.4, two superb lenses, but also the Nikkor 200 micro as well as the 70-200. This latter I was prepared to return, but so far the results are quite good and I wonder if I even need the 85. I do like the micro nikkor for close work though and will hang on to that.

I did make one image in January, from some flowers my sister sent me in lieu of the gorgeous flowers at Dad's memorial that I couldn't bring home to Calgary.

A bronze propeller (ship's screw) found at the Esquimault Naval Base near Victoria. On each blade, one side had been buffed, the other left corroded. I elected to let the image blur in places and it's a 5 image stitch (as I usually do when making panoramas, hating to crop, even with a 22 megapixel camera. I did use some Akvis Enhancer but toned it back to a maximum of about 45% and then used masking to reduce the effect further as appropriate.  It helped add the third dimension back, while masking prevented loss of the softness of parts of the image.

Victoria







Agave


Agave plant from Butchart Gardens, Victoria, B.C. photographed in the rain with my 5D3 which held up very well over several hours of rain.

Fall



Running out of chances to shoot leaves this Fall.

Dinosaur Provincial Park 2012


Went down yesterday afternoon to catch the evening light, stayed overnight in Brooks and got up early to be there at dawn. This was a single image. Made with my 17-40 @ 17 mm.

Fall Colours


Canon 5D3, Lensbaby Composer, extension tube, and the only editing was to turn down the green a tad, otherwise colour as shot. Be sure to click on it to see in larger size.

HIgh ISO

The Stream and Pool image I posted last night was shot at ISO 1600. I would have never considered this high an ISO in the past but my new 5D3 handles it with aplomb and 17X22 prints should not be a problem. I did it because I could see that on the LCD screen, the ISO 100 pictures had very blurred out water totally devoid of the lovely reflections I was seeing. Even 800 didn't help but ISO 1600 and 1/8 of a second at f11 solved my problem. My intent was to use the ISO 100 images as a focus blend in Helicon Focus, then use one of the ISO 1600 images for just the water, but in the end simply blended the ISO 1600 images because they looked so good, then used one of those images for the pond water, and another for the further stream (moving water doesn't go well with focus blending).

The times and equipment are great.

Back To Jura Canyon


Shot this evening. I think everything you see here is natural rather than pictogryphs, though I find the image a little mystical.

Cowboys










 



These three images were made on a workshop this weekend with William Allard, he of National Geographic fame. It was arranged through The Camera Store here in Calgary (that's what it's called), and we met with Bill Friday night to dicsuss what was going to happen, then met west of Longview and switched to four wheel trucks to head up to a branding camp, used only a couple of times a year.

The local ranchers rode in and gave of their day to pose, and  ride, and pose some more. These are real working cowboys, two grand parents, his brother, and their two grand daughters.

The workshop was a great success and we met this morning for critiques of the images. I found the experience great as others had ideas I'd poo pooed but they'd made it work, or I hadn't even thought of, or they did a better job shooting action (not my forte). Anyway a terrific weekend, Bill is great and sharing and helpful and I hope to see him again.

Drain Pipe Continued


This is the version that was not lightened for making the print - despite best efforts to profile monitor and printer and correct screen brightness, the shadows were too deep in the print and I'd added a lightening curve. This is what it was before and is much closer to what I wanted.







And here is what the image looks like in black and white. Now to decide which I prefer. Not easy.

Drain Pipe Cropped


I'm quite pleased with the print I made from the version above. As usual, the thrill of making the image tends to ignore any flaws it may have and it might not hold up over the next few weeks, or I might like it more and more. Sometimes you realize it's just silly, or perhaps clever but absolulely nothing else -  no soul - always a risk with this kind of image. Other times it acquires more meaning or more emotion, or makes you think of connections, contrasts, or similes.

People tend to assume that these relationships that make an image for the artist remain constant, but in fact there are many examples of artists providing alternate explanations for an image's value years later, as their circumstances, experiences and mood change. It isn't a big step further then to imagine that the viewer brings their own circumstances etc. to seeing the print and those experiences may be entirely different from what the photographer had, or planned, or anticipated.

And guess what, that's entirely as it should be.

And below, the original full frame image:



Both are focus blends of half a dozen images, 24-70 L, Canon 5D3, Helicon Focus for the blending, processed in Lightroom 4 and exported to Photoshop for additional work

Bent Drain Pipe


Highway construction dug up and folded this drainpipe. The side I had seen from the road the previous day was good, the view along the bent pipe better, but the far side, that I had not expected anything from and only checked to be complete, revealed this fascinating combination.

As it stands, I think the composition too complex and while I didn't want to throw away anything, I suspect the image might be better without the top. It reminds me of a carnivorous plant. Stay tuned for further developments.

On Landscape - the Online Magazine

Tim Parkin who did the work on comparing landscapes shot with 8X10, 4X5, IQ 180 and even the Sony 900 earlier this year continues to publish the online magazine On Landscape.

It's quite expensive and I think many will reject it out of hand without thinking about just what it's giving us.

There have been technical articles like the above - a huge and very useful achievement, as well as quite indepth discussions by real photographers on the art of photography - as well as book reviews and portfolios.

Given the videos alone, and coming every couple of weeks as it does, this makes the sign up cost pretty darn reasonable - $100 approx. for 26 issues - but that's $4 an issue, no advertizing to pile through, useful stuff in every issue - I think well worth the expense.  It's nicely set up so you can see the beginning of many of the articles without signing up - so do check it out, and consider subscribing as I have done.
