Compared to... contd. Colour Patches
This is basically the same comparison we shot for the Canon EOS-D30 review, however this time we're using a colour corrected image sample for the D1.

We're only measuring colour below. RGB values below were taken from a VGA reduced image (to average colours and eliminate JPEG artifacts) using the Eyedropper tool in Photoshop with a 5 by 5 Average Sample Size.

Resolution Charts
Shots here are of the PIMA/ISO 12233 standard resolution test chart (more available for comparison in our cameras database). How to read the charts: All values are 1/100 th lines/picture height. So the "10" value equates to 1000 lines/picture height.
Notes: Fujifilm S1 Pro sample shot at 6 megapixels (interpolated) thus crops will look much bigger than the other 3 megapixel cameras.

Measurable findings (three measurements taken for each camera):
| Camera | Measurement | Absolute Res. | Extinction Res. |
| Nikon D1 |
Horiz LPH | 1100 | 1300 |
| Vert LPH | 1150 | 1250 | |
| 5o Diagonal LPH | 900 | n/a | |
| Canon EOS-D30 |
Horiz LPH | 1100 | 1350 |
| Vert LPH | 1150 | 1300 | |
| 5o Diagonal LPH | 1000 | n/a | |
| FujiFilm Finepix S1 Pro |
Horiz LPH | 1300 | 1450 |
| Vert LPH | 1200 | 1400 | |
| 5o Diagonal LPH * | 1000 | n/a | |
| Nikon Coolpix 990 |
Horiz LPH | 900 | 1300 |
| Vert LPH | 900 | 1400 | |
| 5o Diagonal LPH | 900 | n/a |
* Visible moiré artifacts
Definition of terms:
| LPH | Lines per Picture Height (to allow for different aspect ratios the measurement is the same for horizontal and vertical) |
| 5o Diagonal | Lines set at 5o diagonal |
| Absolute Resolution | Still defined detail (below Nyquist frequency*) |
| Extinction Resolution | Detail beyond camera's definition (becomes a solid gray alias) |
| n/a | Not Available (above the capability of the test chart) |
| n/v | Not Visible (not visible on test results) |
* Nyquist frequency defined as the highest spatial frequency where the CCD can still faithfully record
image detail. Beyond the Nyquist frequency aliasing occurs
The D1 loses out very slightly to the D30 due to its slightly lower resolution sensor, however it does exhibit far less visible moiré than the D30.
Fujifilm's S1 Pro still rules the resolution roost, chart lines are still defined down to 1300 lines per picture height horizontally which is very impressive for a 3.2 megapixel CCD (remember, "interpolated" up to 6 megapixels).
