Morning Pistes. Nikon D2H, 70-200/2.8 VR

One from the archives – I haven’t been skiing in ages. I think it’s the adrenaline rush that does it for me; what other sport (except skydiving) allows you to go this fast without an engine? Next year, year after…I keep promising myself but life, work and everything else get in the way. It’s important to remember to take time out to relax, observe your surroundings and be inspired again – especially for somebody involved in the visual arts. Perhaps creativity in accounting or tax is best avoided, though. MT

Photoessay: Dawn over Kuala Lumpur

Although not technically aerial shots, the 421-m tall platform (plus hill) afforded by Menara Kuala Lumpur (KL tower) is a great place to get some interesting images of the city downtown at dawn or dusk – though it usually rains in the evening, so morning is a better bet. MT

Update on Nikon D800 focusing issues

It seems that I’m going to have to redo all of my focus tracking and lens evaluation tests: my AF sensor module is misaligned. I’ve come to this conclusion after a) trying out a number of wide angle lenses, all of which exhibit a soft left side when the AF system or focus confirmation dot reports achieving focus; and b) sending it in to Nikon locally to diagnose. Curiously, the problem is only exhibited with wide angle lenses (telephotos are mostly fine), and live view confirms it’s an AF sensor issue not an imaging sensor issue.

The bad is that it’s serious enough to require a new camera because the calibration is a very high precision adjustment that takes time (and unclear if it can be done locally); the good news is that NPS Malaysia made the situation right: a couple of hours after reporting the problem, I met with a representative who informed me a new D800 will arrive next Wednesday, and I’ve been loaned a D3x until the replacement arrives – at which point it will just be swapped out. Kudos to NPS for handling the problem well though – that’s how professional service should work (though a new camera on the same day would be even better…)

Still, a bit of a shame, because I planned to use the D800 for its first commercial shoot this weekend – looks like I’ll only be using it for the stop-down telephoto shots. MT

Coda: It’s interesting just how sluggish the D3x feels when shooting in 14-bit raw mode – just 1.8fps, with what feels like a good 200ms or more of lag between hitting the button and the shutter firing. It’s very noticeable if you put the camera back into 12 bit mode, after which it feels responsive and snappy like it should. Even the menus feel a little laggy, like the camera’s processor is working very hard. The D800, by comparison, runs happily along at 5fps in 14-bit mode – 3x the frame rate with files that are 50% larger, for a total of 450% more data. You don’t feel any lag, and zoomed in images – even 14 bit raw – are very fast to navigate around. Faster than the D700, even. I don’t know how many other people have noticed this, but it’s pretty darn impressive, in my opinion.

POTD: Flambé

_7060984 copy
Baked Alaska. Nikon D700, AFS 60/2.8 G Micro

Flames are a funny thing – they don’t photograph well. Simply, yellow flame is bright because it contains a lot of incandescent little particles; usually, it’s too bright to photograph well relative to surroundings – you land up losing detail in the flame if you have context, or losing context if you have detail in the flame. Blue flame is almost impossible to photograph because most of its energy is heat – there isn’t much in the way of light-emitting incandescent particles. Flames are also very random in an interesting fractal kind of way; photographically that means you’ve got to do many, many takes – four Alaskas, in the case of this shot. And dozens of frames until we got just the right flame.

The problem for food photography – specifically baked Alaskas – is that the lit brandy you pour over the dessert burns blue, which isn’t so great to shoot. Sure, you could composite flames in after, but it would both look unnatural and just be dishonest. So what do we do? Simple: add a little something to the alcohol that makes it burn brighter, and a little yellower.

Interestingly, this is where the high ISO capabilities of the D700 become useful: ISO 6400 with a good amount of remaining dynamic range and very low noise. I don’t think this shot would have worked as well with the D800. MT

On assignment: Bistro food

_7060396 copy
This set shot with a Nikon D700, AFS 60/2.8 G Micro and several SB900 flashes.

I’m seeing an increasing shift in my commercial work these days towards food – as a gourmet (or perhaps as a greedy person) I’m certainly not complaining. Interestingly, food photography actually shares a lot of techniques in common with watch photography – with the huge benefit of not having any reflective surfaces to worry about. But from a lighting point of view, it’s the same.

Last week, I shot what was probably my final job with the Nikon D700 – some highlights of which are presented here. The D800 studio update will probably be towards the end of next week due to job scheduling.

I wanted to use this opportunity to say a few things about both food photography, and draw some conclusions on the D700’s use as a studio camera.

_7060499 copy

Food may not have any reflective surfaces, but it certainly presents some challenges of its own: firstly, temperature. Things don’t look optimally appetizing for that long (think ice cream) which means you’ve got to work quickly, and studio strobes are pretty much out of the question because the heat would make anything fresh wilt in less time than your fastest flash sync speed. The solution I’ve found to that is either use low-temperature LED panels or use flashes. For the most part, I use flashes because they’re more flexible in terms of light output deliverable, and have enough power to accommodate larger setups. LED panels don’t have as much throw or power, and go through batteries like crazy. And there are also color temperature issues – so far, very few panels can deliver a relatively even, neutral spectrum – and those that can are both hideously expensive and not all that bright.

_7060545 copy

The next challenge is actually detail: most people don’t want to look too closely at what it is they’re eating. I mean, a steak looks great as a whole, but I don’t think you want to start looking at meat fibers and thinking about exactly what motor function that muscle did when it was still part of the cow; there’s a huge compositional tradeoff between detail, suggestion, and emotion.

_7060248 copy

Bottom line: food images are about emotion: they must make you feel like you want to eat them. The ultimate litmus test for me is: would I want to order the dish if I saw this image in a menu? Lighting is your one control here: both softness and position of the light sources, and less intuitively, color temperature. (I’ll go into this more in a future article).

_7061864 copy

I’m going to conclude with a few words about the D700 as a studio camera. It may not deliver the most resolution, but it does have a few advantages over say a D3x or medium format – providing you don’t have clients that must absolutely have that pixel count. Firstly, there’ the built in flash with commander function – that was the #1 reason why I went for a D700 instead of a D3s, and I don’t regret it one bit. Speed isn’t an issue, but putting an ENEL4a in the MB-D10 grip gives you both speed and an incredible amount of shooting time: I can easily shoot a full day assignment on one battery. This assignment (2,000 frames in total) was completed with 60% power left over on the ENEL4a, and the ENEL3e in the camera still full. Finally, base ISO of 200 gives your speed lights a boost – and even if you don’t need the extra power, it reduces cycle time as well as extending your battery life.

_7061009 copy

Curiously, the internal flash can’t handle more than about a dozen shots or so in reasonably rapid succession before it cuts out to take a breather – unclear whether this is due to the capacitor’s limitations, or an overheat protection system of some sort to prevent your prism catching fire (which would probably be a fatal disaster considering the camera is both touching your face and made of highly inflammable magnesium.)

I’m looking forward to the quality the D800 brings, though I can’t say I’m so enthused about the amount of retouching it will require – especially for watches and other similar product. But for food, bring it on! MT

I will be attending the World Gourmet Summit in Singapore at the end of April to conduct some sessions for Leica; details to come soon. MT

POTD: Magritte Strikes Again

_8001440 copy
Magritte Strikes Again in downtown Kuala Lumpur. Nikon D800, 28-300VR

Amidst all of the chaos and panic claiming serious ‘issues’ with the new Nikon D800 (see my previous post) – I think it is important for the photographer to serenely rise above the noise (no pun intended) and remember that ultimately, the camera is a tool, nothing more, nothing less. It enables you or gets in your way. All I can say is that from this image alone, the D800 is capable of delivering some of the most accurate color I’ve ever seen. Normally I’d struggle to get the blue right and maintain the rest of the gamut – not so here. The D800 did it effortlessly, with a lens that isn’t known for the accuracy of its color transmission. I really need to get more Zeiss glass in front of this sensor. MT

Popular Nikon D800 woes, problems, issues and solutions

There’s been a lot of brouhaha on the forums recently about the Nikon D800’s various ‘critical flaws’:

1. The camera stops down in live view, so you can’t see anything!

2. You can’t get a sharp magnified live view image, so it’s no good for critical focus.

3. LCD has a color cast.

Let’s deal with these one by one.

1. I don’t consider full time DOF preview to be a problem, actually. Besides, to achieve critical focus accuracy, you should be focusing with the lens at maximum aperture anyway. One of the advantages of live view is that you actually get to see what minimal DOF looks like, unlike with the viewfinder where the focusing screen limits DOF to somewhere around f4.

2. The live view preview image is heavily, HEAVILY dependent on your picture settings because it provides a PREVIEW. So, set accordingly. Note that picture controls don’t affect RAW images unless you’re converting in NX; the settings are stored as a tag in the metadata. I set my picture controls to maximum sharpening to gauge whether an image is in focus or not, the rest don’t matter. (I have a separate set for video.)

Specifically, see below:

Above with standard sharpening set; below with +9 set. Note the difference, specifically with the text. This is at or slightly beyond 100% view. Problem solved.

3. The color is definitely different to the D700/D3/D3s – if I had to say, I think it renders a little warmer. In the image below, both cameras were set to the same WB.

Regardless, you should not be judging color on the camera’s LCD anyway – all images will have to be processed via a computer anyway, and frankly if you’re spending this much on a camera, why would you want to be cheap on your image processing or computer monitor. It’s like buying a Ferrari but only putting 89 octane fuel in it and wondering why the car feels sluggish.

One final word: these are very minor issues. They aren’t deal breakers, and there are workarounds for all of them. Curiously, users of medium format digital have to endure much more – but we never hear them complain about their LCDs, or lack of live view – despite paying ten times as much. Go out and shoot and stop whining. Ultimately, your skill limits the quality of your image far more than the native color temperature of your LCD ever will. MT

POTD: New car obsession

_8001335 copy
New car obsession. Nikon D800, 28-300VR

On a photographic note: the T stop of the 28-300 is much lower than the f stops would suggest, requiring higher ISO. If you want to know the difference between the two, I suggest you come back later for today’s article 🙂 What you can’t see art this size is that this was shot at ISO 1400 – yes, there’s some fine grain if you look at 100%, but guess what – it could have been ISO 50 for all intents and purposes on the web. Downsizing large images (even if noisy at the pixel level) averages out the luminance noise and leaves you with a much cleaner print than you might think.

A mark of today’s blind consumer society: I was attending the launch for the new BMW 3 series locally; overheard was a conversation between two other customers:

Person 1: “It’s so huge inside!”
Person 2: “Really? Doesn’t seem much bigger than the old one to me.”
Person 1: “But it must be, the salesman said so!”

There’s a moral to this story: firstly, don’t believe everything you read or hear: go and verify it with your own eyes, especially if you’re going to be spending your own hard earned money on it – more so these days, since inflation seems to have had a very visible effect on the pricing of goods. Or maybe it’s the aspiring middle class, or both. If something is fit for your purpose, then go ahead and disregard what others – especially those with a clear bias, like salespeople – are trying to tell you. That’s the whole benefit of choice! Remember: this applies equally to anything, be it luxury cars or cameras. 🙂 MT

A very long term (and final) review: The Nikon D700

_1KD_MG_0064 copy

Bear with me here. The Nikon D700 may be a 2008 camera, (ouch, that’s four years old? Why is he reviewing it now?) and even worse, I received it’s successor – the D800 – on 22 March. (My initial review is up, here) It’s now time to close the book on the D700 – its days as my primary workhorse are just about over; I shot my final assignment with it earlier this week. And that’s the reason why I’m reviewing it – I think I’m now qualified to pass an opinion.

Nikon’s pricing has left a gap in its FX lineup – there’s the D7000 at approximately RM3,000/US$1000; the D300s (though hardly ever bought, and arguably bettered by the D7000 in almost every way) at RM4,500/US$1500 or thereabouts; then we’re into FX territory with the D700 at RM6,300/US$2100 and the D800 at US$3000. Notice how the pricing steps up in nice increments: $500-600 gets you appreciably more camera in every increment – well, perhaps with the exception of the D300s, which is to be replaced soon.

_7049641 copy

The D700 was left in the lineup for two reasons: to clear remaining stock, and to provide an entry level option for FX upgraders. And guess what: according to every dealer I’ve spoken to, it’s still selling just as well as the day it was launched. So why does everybody think it’s obsolete? Clearly, because the successor was launched. Hell, even I’m buying one – but only because my D700 has been shot to death and is on the way out; it doesn’t make sense for me to buy another D700 when I could pay a little bit more, and offer more resolution to the clients that require it.

_7047913 copy

To me, the D700 was a landmark camera: the same amazing low light performance as the flagship D3, no compromises in AF or features – anywhere – at a price that was affordable to the majority of serious amateurs, whilst being robust enough to deal with professional abuse. I had two of them at one point. It was the first camera – aside from the D3 – that I felt turned me, the photographer into the limitation, rather than the camera or the lenses. If you could see it well enough to compose, you could get a useable image. If you could aim the camera fast enough, it would focus. And it would track subjects with unerring accuracy.

_7050874 copy

And from a user’s point of view, that’s the all important question answered: yes, it’s good enough. The image quality is beyond reproach; you get 12 extremely clean, high-durability (more on that later) megapixels – which if used properly, is sufficient for any use. The resolution represents a sweet spot between diffraction limits – f27 is about where it starts to kick in – and depth of field. The large photo sites mean that you have a very high signal-to-noise ratio – coupled with high color accuracy and good dynamic range (that’s what I mean about high-durability pixels). In fact, exposed and processed with care, you can get around 13 useable stops out of the camera – which is right up against the limit of its 14 bit raw files. This does require judicious use of the highlight recover slider in ACR and a little deliberate overexposure (a stop is quite doable) – so you have to plan for it at the time of shooting. In any case, any more dynamic range looks unnatural and flat – remember, screens at best can only display 8 bits of tonal range, and even less for print.

Seiko ‘Fifty Three Fathoms’. Nikon D700, 60/2.8 G Micro

Much has been made of the high ISO capabilities of the D3 around the time of its launch; the same holds true for the D700. It isn’t a camera that’s particularly sensitive to color temperature with regards to noise (for example, the D2H and D200 of the previous generation were, due to IR and blue-channel sensitivity issues). Properly exposed, ISO 6400 is clean, and ISO 12800 is useable. To be honest, if you need any higher ISOs than that and you’re shooting wide open with f1.4 lenses, you probably won’t even be able to see the subject well enough to compose.

_7024121 copy
Thaipusam. Nikon D700, 85/1.4 G

Bottom line: image quality remains on par with the best of the DX cameras, even the new 16MP and 24MP ones. The latter may resolve slightly more at base ISO, but they lose out on dynamic range, edge integrity, and anytime you need to exceed ISO 800. Color accuracy is always slightly better, in my opinion. It remains to be seen if the D800 has the same pixel integrity as the D700, given the benefit of four years of development. I’m not expecting miracles due to its pixel density, however.

_7025478 copy

Image quality is the largest factor in the success of a camera as a tool, but usability is right up there, too. Suffice to say that Nikon has been doing this for a long time, and it shows. The ergonomics of this camera are very comfortable, even for extended use, and with larger lenses. In my mind, it balances best with something large-medium – around the size of the 85/1.4, for instance. Larger is a bit front heavy, but still comfortable. If you need more weight, or speed, there’s of course the MB-D10 battery pack – with the right batteries, 8fps is possible. (Curiously, 8fps is also possible without the battery pack if you select flash bracketing, single-shot mode, and hold down the function button to select a 9-frame burst.)

_7022462 copy
Teatime. Nikon D700, Zeiss ZF.2 2/28 Distagon

There are a lot of nice little touches here:
– The metering mode switch is still my favorite of any camera; it’s easy to flip to spot when required, though that’s seldom because the 1005 pixel RGB meter is usually spot on. One doesn’t actually appreciate just how accurate this meter is until you use something else.
– Viewfinder blind and eyepiece lock
– The built in flash. Many people question why you’d want to have this on a professional camera, but clearly those people never work with speed lights – I do all the time, and it’s invaluable to use as a remote commander.
– My Menu.
– The ability to use the multi-selector center button to instantly zoom playback images – to check for sharpness – then toggle between the same magnified point on successive images with the command dial.
– Tethered port caps, finally. Too easy to lose the little screw in plugs on the last generation, and much too expensive to replace.
– The battery grip communicates via a series of small contacts on the base of the camera, and doesn’t require you to remove the original battery and battery door: it’s functional with them still in, and much easier to store and put on/ take off.
– Weather sealing – though I wouldn’t complain if it were fully gasketed like the single-digit cameras, it can still survive a pretty serious downpour unprotected.
– Programmable buttons. Give us more, please.
– DX crop mode – useful when you need more reach in a pinch, but will be better if there was more resolution to support it.
– AF fine tune – very, very important with fast lenses.
– Rangefinder with arrows to tell you which direction to turn the lens in; helpful for manual lenses.
– The LCD is actually good enough for you to be able to judge critical sharpness, and with experience, exposure and color.

But there are also things that need fixing, some of which were addressed with the D800:
– Live view is far too complicated to access – rotate drive mode dial, hit shutter. Should just be a button. (fixed)
– AUTO should be an option on the ISO selection button. (fixed)
– It’s difficult to see the entire finder with eyeglasses – really needs a higher eye point.
– DX crop mode – the masking is far from obvious.
– The focus points could be spread out more; often I still have to shift and recompose even using the extreme points. Curiously, the camera can still track subjects even if they move outside the AF points – it uses the color of the subject and the metering CCD to do this.

_7046623 copy

Let’s talk a bit about AF. Simply, it works. I use either single point mode, with 11 selectable points – when shooting static subjects, and then switch to 3D-tracking with 51 points on the back toggle switch when shooting action or photojournalism. Once you lock on to your subject with the center point, you can recompose and the camera will automatically track. With fast lenses, AF-C is imperative because of field curvature and small movements in either camera or subject – either situation will rob critical sharpness. AF obviously works better when shooting at 5fps because there’s more information reaching the AF sensor, so it’s easier for the camera to predict where your subject is going to go; it’s still good at 8fps, though. Same underlying 51-point CAM3500FX module as the D3-series.

_7045802 copy

Battery life is excellent. A standard EN-EL3e cell will last me a day; easily a thousand shots or more, with moderate LCD use. With the grip and EN-EL4a cell from the D3 series, you’re looking at easily 5000 or more frames – more than enough for a day of use for even the most prolific photographers. And you can still keep your EN-EL3e in the camera if you’re worried about running out of juice. Simply put, this is the longest-lasting camera that Nikon makes, period.

Nikon D700, 16-35/4 VR

This is actually a very different review to the one I wrote in CLICK! magazine shortly after the release of the camera; I was shooting with a D3 at the time, and didn’t feel that impressed by the camera. But I think I was missing the point: the fact that I wasn’t really missing anything, either, should have been more impressive: flagship performance for almost half the price.

Four years later, I’ve shot nearly a hundred thousand frames between two D700s; both have performed nearly flawlessly. My primary body is throwing the occasional black frame, which suggests a sticky shutter issue. I’m loath to send it in for replacement because my camera is also quite heavily modified, which I’m afraid Nikon will undo if it appears at their workshops. At one point, I was shooting all Zeiss manual focus glass; I discovered the hard way that the viewfinder wasn’t really up to the task of focusing accurately with very fast lenses. My finder has a new screen – a Type J bright matte with micro prisms and split-prism from the F6; it doesn’t fit natively so it had to be filed down. The screen has been perfectly shimmed to be planar and perpendicular with the sensor, and the mirror zero return position and alignment adjusted for the same. Basically, as close to perfect WSYWIG as possible. I’ll probably have to go through the same process again with the D800, but I doubt I’ll bother with the focusing screen as I prefer the Nikon AFS f1.4 lenses these days.

It’s time to answer the inevitable question of D700 vs D800: it’s not as clear cut as you might think. Yes, the D800 offers higher resolution and video but at the expense of per-pixel noise and demands on lenses and technique; in that sense it’s a much less forgiving camera. You’re also giving up the potential of full resolution shooting at 8fps. Ergonomically, both are good; the D800 takes a slight edge due to refined controls, however I personally find the D700 grip more comfortable. The D700 is more of a general, do-anything, go-anywhere camera, but the D800 is a specialist tool that can produce amazing results – under the right conditions.

Although both are clearly interchangeable from a function point of view, if we examine the strengths of each camera, I think the balance splits as follows.
D700 if you:
– Do not make prints beyond 2×3 ft, or use images for digital purposes only
– Shoot a lot of sport or other things that require high frame rates
– Aren’t willing to invest in the best glass or technique

D800 if you:
– Need the resolution for large prints
– Need the increased dynamic range
– Need video capability

In the meantime, my D700 goes into retirement as my backup/ high-speed body. I think I know what kind of beast it is now: the Goldilocks camera: not too big, not too small, just right, and incredibly versatile.

A quick note on Nikon D800 autofocus…

Up to this point, I’d been shooting the camera with the same autofocus settings I used on the D3 and D700 – which share the same CAM3500FX AF module. I think I just discovered why the AF system doesn’t seem to be as precise as before.

Previously, I used single point AF-S for static subjects, and 51-point dynamic 3D tracking AF-C for everything else. I could lock on with the center point, focus and recompose, and everything would be fine. It seemed like a good starting point for the D800.

Turns out I was wrong. Single point AF-C is MUCH more accurate and slightly faster than 51-point dynamic 3D. It’s solved a good number of my AF issues. Remains to try it out tonight when the light gets low to see if performance is improved under those conditions too. MT
