What do the different Canon DSLR image size settings mean? That is a remarkably sharp picture of the screen. The higher the quality setting, the larger the. Whether you're a beginner or a pro, a DSLR offers three tempting ingredients: manual controls, excellent picture quality and interchangeable lenses.
The picture quality of a digital camera depends on several factors, including the optical quality of the lens and image-capture chip, compression algorithms, and other components. However, the most important determinant of image quality is the resolution of the CCD. The more elements, the higher the resolution, and thus the greater the detail that can be captured.
In 1997 the typical native resolution of consumer digital cameras was 640×480 pixels. A year later as manufacturing techniques improved and technology progressed the emergence of megapixel cameras meant that the same money could buy a 1024×768 or even a 1280×960 model. By early 1999, resolutions were as high as 1536×1024 and before the middle of that year the two megapixel barrier had been breached, with the arrival of 2.3 million CCDs supporting resolutions of 1800×1200. A year later the unrelenting march of the megapixels saw the three megapixel barrier breached, with the advent of 3.34 megapixel CCDs capable of delivering a maximum image size of 2048×1536 pixels. The first consumer model 4 megapixel camera appeared in mid-2001, boasting a maximum image size of 2240×1680 pixels. At this level, raw resolution is arguably little more than a numbers game and secondary to a digital camera’s other quality factors.
