Image Size / File Quality Options
The D1x offers a good variety of image size and quality
settings; two TIFF (RGB and YCbCr), RAW (uncompressed or losslessly compressed)
and three JPEG modes plus B&W. Resolution wise you can choose from
3008 x 1960 (5.9 megapixel) or 2000 x 1312 (2.6 megapixel - original D1)
sizes.

Standard Test Scene |
To give an impression of what some of the combinations
of image size and quality produce the table below is a cross reference
of some of them:
- 3008 x 1960 TIFF RGB
- 3008 x 1960 TIFF YCbCr
- 3008 x 1960 RAW (converted in Nikon Capture 2)
- 3008 x 1960 JPEG FINE
- 3008 x 1960 JPEG NORMAL
- 3008 x 1960 JPEG BASIC
- 2000 x 1312 JPEG FINE
- 2000 x 1312 JPEG NORMAL
Settings:
ISO 125 / Exposure: 1/10s, F8.0 / Sharp.: Normal / Tone: Auto / Colorspace:
sRGB.
Crops below are of the same 240 x 120 area of each image
nearest neighbour magnified 200%.
It's interesting to note the difference in contrast between
the TIFF/JPEG images and the RAW converted image. We converted the NEF
using the standard 'Neutral.Set' adjustment settings (basically, this
is no adjustments), saved as a TIFF and then cropped out the required
area. Colorspace was set to sRGB. Otherwise it's clear that quality is
excellent (we'll talk about this in more detail in the Image Quality section
of this review), the lower quality JPEG compressions provide relatively
good quality (although artifacts become apparent at BASIC). The smaller
2000 x 1312 image size provides a super-crisp yet economical (storage
wise) option.

Black & White
In addition to the image quality and size options you
can also select B&W instead of colour. In this case the camera only
outputs a grayscale image, all colour information is discarded.
Settings:
ISO 125 / Exposure: 1/10s, F8.0 / Sharp.: Normal / Tone: Auto / Colorspace:
sRGB / Large FINE JPEG.

ISO (Sensitivity) Adjustment
The D1x allows you to choose from 1/3, 1/2 or 1 EV steps
betwen ISO 125 and 800, at 1/3 EV steps this provides a total of 9 different
ISO equiv. sensitivities. Additionally there are two additional sensitivities
accessible through the ISO boost custom setting (CSM 31) which are equivalent
to ISO 1600 and 3200. To give an impression of noise levels at different
sensitivities the same scene was shot at 1 stop (1 EV) steps from ISO
125 to ISO 3200 (HI-2) in both good and low light situations.
Settings:
Sharp.: Normal / Tone: Auto / Colorspace: sRGB / Large FINE JPEG.

An amazingly good performance, almost no visible noise
all the way up to ISO 400, at ISO 800 there's noise but it's nothing too
distracting. Yes, there's noise at even higher ISO's but look, it's random
noise, not pattern noise as we saw on the D1. This will be of great relief
to most D1 owners / users as they will appreciate how difficult it is
to remove pattern noise, but how natural and almost 'film grain'-like
ranomd noise is.
