The Nikon D100 was launched in 2002 and was among the first DSLR cameras. Its features are very similar to those of the D1, the first SLR launched by Nikon. In appearance and size, it is similar to the N80, which was a film camera introduced by Nikon and considered as one of the best cameras for filming.
The D100 camera offers a wide range of high quality combinations and image sizes
The full megapixel resolution was 3008 x 2000 pixel image size, which is equal to 6.1 megapixels. In this camera, photographers have the option of saving RAW and uncompressed images. It enables you to select from three levels of JPEG compression, which are 3008 x 2000, 2240 x 1488, and 1504 x 1000. It also enables users to choose from three colour modes. Two of the modes are designed for RGB colour space. So these modes are usually used for portraits and stills. The third mode has been designed for taking pictures of nature and landscapes, as it delivers richer shades of green and a more natural balance of colors.
The D100 has four levels of image sharpening. In the auto mode, the camera automatically adjusts the sharpness according to the lighting conditions and the type of image selected. You can also select low, high or normal settings manually, according the lighting available at the scene.
