The process of interpolating is called demosaicingNote: Dirty Sensor

NOTE: B&W vs. GRAYSCALE

Technically, in digital photography we make grayscale images, AKA Black & White conversions, using the color channels during the conversion.Color SpaceVarious Mathematical models to represent color as it applies to JPEG camera settings

sRGBWebAdobe RGBPrintsColor GamutColor gamut choices are important when printing from JPEG files.

For better prints, set your camera to Adobe RGB (wire frame) for printing from JPEGs. A RAW file does not require a choice of color gamut. (sRGB (solid) is smaller and standard for web.)JPEG & RAW

RAW File as shotRAW File processedRAW File B&W ConversionRAW FILESAre not compressedAre larger & take up more memory Are processed and converted by you (not your camera)Are proprietary (not universal like JPEGs) i.e. NEF & CR2Are at least 8-bits in colorAre NOT restricted by sRGB or Adobe RGB color spacesHave more latitude for adjustments in the highlight and shadows(Are sometimes admissible in a court of law, forensics)Are what you will be shooting with after the first assignment
