36 megapixels and what does that mean to
artists who photograph their own artwork |
This page was updated on April 2 |
On March 22, Nikon came out with the 36 megapixel D800 for a
reasonable price of only $3000. I say reasonable because that was what the
D700 cost when it was released almost four years ago. And Canon came out with the second
update to their popular 5D, the 5D3. 22 megapixels for $3500. Both full
frame (35mm size) sensor cameras. Don't be fooled into thinking that 36
megapixels is better then 22 megapixels or that for $3,500, the Canon will
be better than the Nikon for $3,000. At anything over 10 or 12
megapixels, it's based on what the photographer needs the camera for. In
fact, when Canon came out with the 21 megapixel 5D2 a few years ago, I was contacted
by an artist who was thinking of spending $3000 to upgrade their
current camera, incorrectly thinking the higher megapixel count would
improve the images of their artwork. |
What can you do with 36 megapixels |
It's an advantage if you need to pull a detail section
out of an image without having to take any additional pictures. It's also
an advantage if you can't get close enough to fill the frame with small
items because it allows severe cropping and still having enough pixels for
jurying.
But on the other hand, it magnifies any imperfections in the lenses you
use. And a sturdy tripod will (with any camera) help maintain
quality in your images. So if you're thinking of using 36 megapixels because your lens
can't focus close enough, a new lens, preferably a dedicated macro lens, would be a much better and less expensive
investment. |
How many pixels is 36 megapixels |
The pixel size captured by the D800 is 7360 x 4912. If shooting maximum quality JPEG, the file size is approximately 16
megabytes and too large for most email servers. RAW files range from 41 to
74 megabytes, depending on compression, and a TIF is 108 megabytes. These
are enormous files to work with and store on your computer. Shooting 36
megapixels will require computer upgrade planning. |
Not a reason to hire a photographer |
It's NOT a reason to hire a photographer. I have a D800 on order.
It's a decision I made two years ago, only because I've needed a second
camera body and have been waiting for the rumored replacement for the
D700 I've been using. |
D800E |
I'm actually getting the D800E, the version without an
anti aliasing filter. With the expectation of slightly improved image
quality, more to the lack of the anti aliasing filter than the number of
megapixels, I've also upgraded my lenses. I recently purchased the Zeiss
50mm f2 ZF.2 and the Zeiss 100mm f2 ZF.2 macro lenses since 99% of what I
shoot is artwork using macro lenses. |
About the Anti Aliasing (AA) Filter |
Most DSLR cameras have an anti aliasing filter in front
of the sensor to slightly blur the image to prevent a moire pattern in the
image. Most images containing a moire pattern are of man made things
containing repeatable patterns,
like clothing and architecture. From
DPReview: If a scene contains areas with repetitive detail
which exceeds the resolution of the camera, a wavy moiré pattern can
appear, Anti-alias filters reduce or eliminate moiré but also reduce image
sharpness.
Nikon also has a good explanation on their web site. |
