Detail is fairly good in this image, though colours would benefit from being slightly more saturated.
Here the D30 does a better job of capturing colours with good vibrancy.
Despite a lower pixel count, the D30 is capable of resolving similar levels of detail compared to its more pixel-packed rivals.
Another image with decent detail, though there is noticeable purple fringing to the right of frame.
Shot at maximum wide angle, equivalent to 28mm. Note the blown highlights on the boat and fringing to the right of frame.
Zoomed in 5x to a 140mm-equivalent focal length.
The D30 should be capable of focussing 1cm from your subject, but when shooting this image it refused to focus closer than 5cm, regardless of shooting mode.
By ISO800 colour speckling is clearly visible in neutral tones and shadow areas, and though plenty of detail is preserved, image noise is starting to overpower it.
Regardless the metering method used, the D30 wouldn't correctly expose this scene and has exposed solely for the highlight areas.
