Compared to... contd.

Now we can move on to our archived test charts, we'll now compare the E-10 to other professional offerings on the market: Nikon D1, Canon EOS-D30 and Fujifilm S1 Pro. Colour patches below taken in daylight with Auto WB setting.

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.

Unfortunately the E-10 didn't get the white balance quite right here leaving everything with a "cool" (blue) cast, we went back and re-shot the chart and got identical results, so to be fair to the other cameras we have to use this shot for comparison. Again, less saturated but still fairly accurate colours.


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):

* 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 E-10's 4 megapixels perform well producing detail a little better than the current crop of professional digital cameras, all but the S1 Pro which still manages to keep its resolution crown despite only having a 3 megapixel sensor (which is then internally interpolated to 6 megapixels).
