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.

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).
