Meaning, even if you shoot RAW and your preview on the LCD shows B&W, any RAW converter like LR or ACR will show a color image.
Understand that no matter what you do, if you’re shooting digital, your camera is going to take a color image, and then process it to provide you something black and white. Meaning, even if you shoot RAW and your preview on the LCD shows B&W, any RAW converter like LR or ACR will show a color image. The one major caveat to that is if you’re shooting a Leica M-Monochrome, which, unlike cameras with conventional sensors, has no need for color filters for individual pixels, thus it requires no interpolation for the calculation of luminance values – read: You get actual B&W in RAW.
