Nikon D300 Studio resolution / JPEG and RAW results
|
 |
|
To measure and compare the Nikon D300's resolving power we photographed the Enhanced Digital Camera
Resolution Chart with it and a number of rival models, each using their
best quality JPEG and default image tone and sharpening settings. We tested the Nikon D300 using the Nikkor DX 17-55mm f2.8 lens at all apertures and selected the sharpest result.
The crops are taken from the original images, saved as High Quality JPEGs
in Photoshop CS2 and presented here at 100%. Each number represents 100
lines per picture height (lpph), so a figure of 20 means a resolution of
2000 lpph. |
Set to Large Fine JPEG mode, Standard Picture Style, and fitted with a Nikkor DX 17-55mm f2.8 lens at f8, the Nikon D300 resolved 2250 and 2300 lpph of horizontal and vertical resolution respectively. This is a small but measureable improvement over the 2200 lpph scored by the D200 in our tests, although to be fair they were taken with a 50mm f1.8 prime lens. We will test the D300 again with the same lens in the future and report back.
The D300's scores here rank it above the 10 Megapixel Canon EOS 40D, although as we illustrated in our Sony A700 outdoor resolution page, this doesn't necessarily translate into that much greater detail in real-life subjects. Speaking of the Sony A700, it delivered slightly better results than the D300 with its default settings and fitted with the DT 16-80mm lens. We should also note the D300's JPEG studio resolution results are only fractionally better than the D80 as seen in our 10 Megapixel group test, so anyone thinking of upgrading for a significant boost in resolving power should think again.
The D300 can record greater detail than seen in its default JPEGs below, but you'll need to shoot in RAW to unlock it. Scroll to the bottom of this page to see RAW resolution results.

Nikon D300 Studio resolution: JPEG versus RAW
We photographed the test chart in the D300's Large Fine JPEG plus 14-bit RAW mode, allowing us to directly compare images created from exactly the same data. Below are crops taken from the original JPEG file alongside the RAW version, processed in Nikon Capture NX 1.3 - 23092 using the default settings, saved as a 16-bit TIFF, then opened in Photoshop. As you can see, the RAW version, even without tweaking, reveals better defined details and a boost in resolving power.
As we also saw on the Canon EOS 40D, the D300's default JPEG files can certainly handle a little additional sharpening, but the RAW result is still ultimately preferred. So again if you want punchier output from the D300, consider a slight in-camera boost in sharpness and contrast, or better still, shoot in RAW.
Now let's check out the camera's performance at different sensitivities in our Nikon D300 noise results page.
