A range of test shots are shown over the next three pages. Here, the full size image has been reduced for bandwidth purposes, and a crop taken from the original full resolution image has been placed below it in order for you to gain an appreciation of the overall quality. The following pages consist of resized images so that you can evaluate the overall exposure. For those with a dial-up connection, please be patient while the pages download.
Nb: The D200 has a large range ISO settings at 1/3 EV intervals from 100 to 1600. Above 1600 are three additional optional settings taking the maximum to 3200 ISO. Only the full EV settings are shown here.
These test shots were taken outdoors on a bright but overcast day using automatic white balance and program exposure mode with multi-segment metering, in normal colour optimization mode.
1/125th, f5.6, ISO 100
At the minimum sensitivity setting, as one might expect the image is very smooth and noise-free, with plenty of fine detail even in JPEG mode.
1/180th, f7.1, ISO 200
Worryingly, a tiny trace of mid-tone image noise is visible at 200, although it barely affects image quality, and colour rendition and detail are still very good.
1/320th, f9.0, ISO 400
Progressively more noise at 400 ISO, although it is still very well controlled, and is still restricted to the mid-tone areas.
1/350th, f10, ISO 800
At 800 ISO the noise level suddenly takes a big jump, and is now visible in some of the lighter tone areas as well. It does bear a slight resemblance to film grain though, so some people may like it.
1/500th, f11, ISO 1600
At 1600 ISO there is now a great deal of noise across the entire image, although it doesn’t seem to have affected overall colour rendition, and there is no random colour speckling.
1/640th, f14, ISO 3200
In this optional high-speed mode at 3200 ISO the image is very noisy and degraded, a lot of detail has been lost and colour rendition has also largely broken down. There are some banding artefacts visible too.
