The Nikon D2X: A Survival GuideImages: The Proof is in the Pudding While I've been very happy with the image performance of all of my Nikon D-SLRs
and the overall image quality I've been able to get on large prints, the D2X
is the first one that really lets me feel my large prints can go toe to toe
with prints from medium format cameras and hold their own from a technical
perspective. Obviously I can't show you that here on the web, but Nikon is
certainly making it a point to show example large prints where ever they
show the D2X which will give you some idea. Perhaps most exciting is that it
is less work than with earlier cameras to generate those prints. The native
resolution reduces the need to fiddle with careful rescaling and I've found
I also need to do much less work on selective sharpening. In addition, the
native color is already rich & quite accurate as well as being complemented
by the most accurate flash & flash-lit color I've ever seen with a digital
camera.
The very high resolution does require a little more care. Reports on the web
of un-sharp images are probably in some cases related to the very small
pixel size and corresponding need for increased shutter speed to keep the
image sharp. Remember that almost any perceptible motion of the camera is
going to blur the image when you each sensor measures something like 1/6000
of an inch on each side.
The Auto-Focus controversy I get asked several times each day "what about the auto-focus on the D2X.
I've heard it has problems." Realistically, I'm sure that out of the many
thousands of D2X cameras shipped there are some that have issues. But based
on my experience with lenses including the 12-24, 24-120VR, 70-200VR,
200-400VR and 600f/4 the D2X locks in as well or better than the D1/D1H/D1X
and while it might be a little slower than the D2H in some cases, it is not
by much. The only target I've had problems with is dark birds against a blue
or light sky. This is tricky for any camera, but the D2X doesn't seem to
handle it as well as the D2H.
One possibly important tip is the poorly documented (or at least poorly
explained) setting 4 under AutoFocus. When ON (the default for the D2X), the camera will stay locked on
its AF target even if something gets in the way. This is great if you're
shooting an athlete going behind an obstacle, but not so great if you want
the camera to lock on to whatever you are pointing at. I've turned mine off
to help me acquire focus as quickly as possible when subjects appear. Aside
from that I haven't had to do anything special to get my D2X to perform well
in a large variety of indoor and outdoor circumstances. I don't know, but I
suspect those reporting substantial AF issues have problems specific to
their particular camera, as there don't seem to be any substantial product
wide issues.
Buying Light
Not entirely content to just believe my eyes and my clients' eyes on this, I
loaded up the excellent Imatest image analysis package and compared the
color fidelity and noise on a series of ColorChecker test shots ranging from
ISO 200 to ISO 3200. Since interpreting Raw files is a matter of preference,
I used in camera JPEGs with the camera set to Auto white balance, under an
even sunlight with slight haze. What I found was a surprise even to me.
There was virtually no loss of any meaningful image quality at ISO 400 and
nearly none even at ISO 800. Even ISO 1600, which I tend to only use for
indoor sports, tested very well and visually was almost identical. Only at
ISO 3200 was there really visible (and very visible in the test image)
increase in contrast and decrease in color fidelity. Another big difference
this test showed from prior D-SLRs was the sophisticated in camera noise
reduction. Some noise actually decreases as the ISO increases. That's a
great thing for color charts, where we're interested in optimizing the
evenness of color, but of course will cost you in edge detail. The best way
to see for yourself exactly what the noise reduction does for and to your
images is to shoot some Raw images and then tweak the Noise Reduction
settings in Capture and notice the results. Note that by default Capture
will turn on Noise Reduction for high ISO images because Nikon realizes it
is necessary to combat the inherent sensor noise in a 12+MP sensor.
For those who want to see all the nitty-gritty, we've posted all the result charts for you.
Speaking of Buying Light: Flash with the D2X
High-speed Crop mode I still really enjoy HSC (high speed crop) mode, but it does come with a
couple caveats. First, you've got to remember that you're shooting at twice
the normal focal length of the lens--about 1.5x for the "digital multiplier"
and about 1.5x for the crop mode. This gives you a very small effective
Depth of Focus and a very small tolerance for camera shake. So you'll need
to have plenty of shutter speed. Remember the old rule about 1/FocalLength
for your minimum shutter speed? It's not a bad idea to keep that in
mind--except that your focal length is twice that of your lens. Second, the
crop marks on the viewfinder, while well implemented, are a little tricky to
use. Your eye doesn't do as well noticing whether your entire subject is
inside the crop marks as it does keeping track of whether it is in the
viewfinder. The result is likely to be some "chopped" limbs until you get
used to allowing enough room. When in doubt remember you can always use the
"full sensor" mode and crop later.
Raw files & Software Support Obviously shooting Raw files is a major reason that many photographers have
purchased the D2X. Many have been surprised by how excellent the JPEGs
are--given the camera's state of the art Auto white balance, low impact JPEG
compression and staggering native resolution--but Raw files are still "the
main event." Unfortunately the D2X Raw files have several obvious and
some not so obvious differences from previous raw files which have made
support from non-Nikon raw converters difficult.
In particular Nikon has begun encrypting (or "encoding" if you prefer) the "as shot" white balance
information, which has resulted in Adobe first delaying support for the D2X
until ACR (Adobe Camera Raw) 3.1 in late May and then stating that even then
it will not use the "as shot" data. The upshot will be that photographers
using ACR with D2X images (when it is available) will need to manually
adjust the white balance for all of their images. Personally I like the
color rendition of Nikon Capture and the workflow of using Photoshop so I
really wish that Nikon would just make Capture a plug-in to Photoshop and
make it externally scriptable by image management applications (like
Photoshop is) and side-step the issue, at least for now.
We asked our 2500 forum regulars, almost all of whom own either Nikon or
Canon D-SLRs (mostly Nikon and mostly more than 1 each) what they thought.
Out of those who've responded, so far 89% think Nikon should document the
NEF file format, 7% think they should at least not encrypt it, and 4% figure
they should be allowed to do what they want with it. Feel free to chime in with your thoughts. The good news is that D2X Raw
files do have a nice large preview in them so there is less need to process
the NEF. And of course JPEG+Raw mode provides some of the best of both
worlds.
Getting it right in the camera
Storage, storage and more storage With every JPEG+Raw image from the D2X consuming 20MB (and that is with
compressed Raw files), I've found myself filling up cards, portable storage
devices (like the Epson P2000) and my hard drives. Since I wrote about this
already in DPS 3-4, I won't belabor the point any further, but I do know
that many shooters, including myself, are going back to just shooting JPEGs
for many assignments to keep things smaller, faster & simpler. With the
color right out of the camera having gotten so good and Capture as well as
Bibble able to work with JPEGs now--plus the stumbles with Raw file software
for the D2X, they may be having a renaissance. In my case I usually wind up
shooting JPEG+Raw but often delete the Raw images (using Delete
Corresponding Raw image command in DigitalPro) for all but a few of my shots
that I might want to work on further in Photoshop. For the rest I just keep
& use the JPEGs.
Wireless with the WT-2 The good news for wireless shooters is that the WT-2 is a big step up from
the early to market WT-1. First and foremost, the configuration is easier
and more flexible--although it still requires many steps and some knowledge
of networks. Second, the WT-2 now supports 802.11g, with a theoretical
capacity of 54Mbps (Mega-bits per second) versus the 11Mbps of the WT-1.
However, you should note that you can only operate in "g" mode if you have
an access point. If you just connect "ad hoc" to your laptop or desktop
you'll be limited to "b" mode. Fortunately there are now "palm"-sized APs. I
own the D-Link version which I can even power off my USB port for field use
(see the New Product section below).
The Connection Wizard on the WT-2 walks you through the steps of assigning
an IP address to the camera (it can also use DHCP, which is a great
innovation), picking a wireless access point with which to connect (it was
easy to connect to my 802.11g access point even using the latest WPA/TKIP
security, which was a pleasant surprise), and then indicating the ftp server
you want to use. I started with the default ftp server that comes with
Windows XP (part of the IIS application--which is not always installed by
default by is on your Windows CD). Once I poked a hole in the firewall for
the ftp port (normally 21) ftp transfer worked flawlessly, and the camera
clearly indicated the transfer progress. To ensure maximum reliability I use
my Digital Camera Battery on the D2X to keep it alive while I'm using the
wireless mode.
Like all wireless connections, performance degrades quickly with distance.
Even with the EA (Extended Antenna), image transfers began slowing down as I
moved more than 20' from the base unit. At 5' from a dedicated access point
I could transfer images as fast as 1 Megabyte per second (about 7-8 seconds
for a JPEG, 11-13 seconds for a compressed NEF and 20 seconds for an
ucompressed NEF). When using the camera in a remote
location (monitoring a bird nest or feeder for example) I quickly decided to
use the "send JPEGs" only mode to make things move along faster, figuring I
could use the NEFs from the camera if I really needed them. At 50'-80' the
image transfer rate from the unit to a wired access point which also had an
antenna was about 400KBytes/second, or 20-30 seconds per JPEG or compressed
NEF--with a pause of about 5 seconds between the NEF & JPEG if I opted to
send both. The good news is that the camera firing is quite quick (as with
tethered shooting, it happens when you let the mouse up on the Shoot or
AF&Shoot button). For speed I pre-focused and only used the Shoot button.
Nikon has done a great job of recreating the camera display in Capture, so
you can see highlights ("blinkies") and the RGB Histogram as your images
arrive. And since you can also control the camera's settings you can
actually do something about it without having to manually re-visit the
camera site. This is a huge advantage over the original WT-1. Admittedly, I
could in many cases accomplish these same tasks using a very long Firewire
cable, but those exceed the official Firewire spec, so they sometimes have
their own problems and of course are often not practical. The one command I
wish Nikon had added was a setting to control whether the NEF or the
NEF+JPEG are sent, but that is not currently supported.
In ftp mode you still need to fire the camera manually or with a radio
remote. But another touted advantage of the WT-2 is the ability to control
it from your PC. The WT-2 supports PTP which allows 2-way communication. This is a slick alternative
to needing a radio remote & a wireless connection and operates the same
was as more traditional tethered shooting using Capture. The basic connection
parameters are all shared with the ftp mode, so it is only the specific PTP
pairing & operation that need to be defined. Pairing is a one time "security
connection" between a computer & the camera--much like Bluetooth devices
use. It is done with a special Wireless Connection Utility that Nikon ships
with the WT-2. Once you have paired the camera you can control it using
Nikon Capture 4.2 or later. It took me some trial, effort and a call
to Nikon Support to get it to work. Fortunately David in Support cracked the
code. In my case I needed to press and hold the checkerboard button when
pairing the computer and camera for the first time. Just pressing &
releasing didn't do the job in my case, although Nikon has confirmed that
normally just pressing the pairing button should be enough.
Wide-area wireless: For many years I've thought that the "right" way to sell
digital cameras would be with some type of always on connection that could
wirelessly be sending images to "the net" as you shot them, so they would be
instantly available to you for processing, sharing and printing. Ironically,
except for a few demos by Philippe Kahn and LightSurf the industry was very
slow to address this issue from the camera side--while in the meantime the
cellphone industry has leapt into the camera+phone business in a big way.
One result is that Nokia and Motorola now produce far more cameras than
either Nikon or Canon. The camera makers have suffered from the lack of a
good way to send images. Only recently has the widespread availability of
wireless hot spots started to make interconnection feasible.
Now the mind blowing part (at least to me): With the WT-2, once I set the camera to connect to a particular network, it painlessly and seamlessly sends my images off as they are shot. And the destination no longer has to be local. It can be any computer connected to the internet. With Internet hot spots popping up all over, this means that I can be at any "un-wired" venue and have my images whisked away to my studio as I take them--from anywhere in the world. Obviously large publications and news organizations have been setting up this capability for a long time using first generation wireless devices and portable access points, normally with local editors on laptops, but with the WT-2 the process has become simple enough and effective enough that it is truly within the reach of any photographer who has a need. Of course the WT-2 (and a D2X) are still very expensive tools and the capabilities are still limited. But they show a very promising start into the world of wide-area imaging for Nikon. Over time, if we are going to continue to think of Nikon & Canon as imaging leaders they will need to adapt to this new market aggressively and take a leadership position. I'd look for point and shoot that can send image wirelessly to photo sharing sites or via the cellphone network before too long. All the pieces are already there for cameraphone owners or gadget savvy gurus, but have yet to be packaged for the volume digicam owner. The Bottom LineAs you've no doubt guessed by now, I really like my D2X and am very happy I bought it. But something you may not have guessed is that it has also helped me appreciate my D2H even more. On the one hand I can compare the "dripping" detail on my large D2X prints favorably with those from a medium format film camera while on the other hand when I look at my computer screen or 8"x10" prints, those from the D2H measure up head to head with those from the D2X. And the big bright pixels on the D2H still give me a nice solid feeling about my images and their quality. I haven't shot with the D2Hs yet, so I can't speculate on how much of an improvement over the now much cheaper D2H it is. Full Disclosure: As with my D2X, I bought my WT-2 and antenna, although it is a lot of money for an accessory. In my case the business justification has to do with the dynamics of remote wildlife photography. With a radio remote I can fire the camera perfectly well, but have to return to the site--possibly disturbing the animals I'm trying to photograph--to retrieve the film card and review my images. With the WT-2, my laptop and the D-Link pocket router I purchased to use with them I can review the images as I shoot and even control the camera settings live. This greatly increases my productivity in those situations as well as decreasing the amount of stress on the animals. DigitalPro TipPro Shooters LLC has released DigitalPro 3.1, with full support for the Nikon D2X and Nikon D2Hs, plus added support for portable storage devices such as the Epson P2000.
