- The majority of high-quality images are shot at 300dpi* (standard print quality) and then downsampled* to 96 dpi or 72 dpi (standard digital quality). To produce high-end print images, at 2400dpi, you'd have to invest in expensive gear. These images will cost you thousands of dollars.

- In a digital camera, the image sensor handles the task. The sensor is covered with photosites, which are electronic doodads (that's the technical term) that collect the light data needed to create the image pixels. Digital-camera image sensors come in two flavors: CCD (charge-coupled device) and CMOS (complementary metal-oxide semiconductor).

- The performance of objective image quality assessment (IQA) models has been evaluated primarily by comparing model predictions to human quality judgments. Perceptual datasets gathered for this purpose have provided useful benchmarks for improving IQA methods, but their heavy use creates a risk of overfitting. Here, we perform a large-scale comparison of …
