पहले तो हिन्दी चिट्ठे पर अंग्रेजी में प्रविष्टि करने के लिए क्षमाप्रार्थी हूँ। पर बात ही ऐसी है थी। मुझे थोड़ा बहुत डिजीटल फोटो वगैरह लेने को शौक है। डिजिटल कैमरा वालों में कैमरे की पिक्सल शक्ति की चर्चा होती ही रहती है। इस पिक्सल शक्ति के बारे में यहाँ वर्णित लेख से अच्छा लेख नहीं देखा। आप भी ज्ञानवर्धन करें:

TheTechLounge Beyond Megapixels Part I

A photosite (one of the millions of receptors on a sensor that capture each pixel) on an APS sized sensor are larger than a photosite on a 2/3” sized sensor, and due to its larger size, it can capture light more easily. This light is digitized into the information that makes up your final image. Analogously, imagine 8 million 16oz cups versus 6 million 5-gallon buckets that are all filled with water. The water is then poured into two rectangular reservoirs measuring 300 feet by 150feet. While the area of water in the two reservoirs is equal, the water collected from the 5-gallon buckets is much, much deeper. So it is with the information captured by cameras with larger photosites. The images produced from a DSLR are generally deeper, with superior dynamic range, color depth and detail resolved (albeit smaller numerical resolution).
