What is the difference between RAW images and another uncompressed format like BMP?
In: 35
In other words: RAW is what the camera actually “sees”. BMP is the dumbed down version that human eyes can interpret. Because camera sensors can (and usually do) have significantly more visual range than human eyes, when one translates from RAW to BMP, a lot of the information is lost (either through compression or clipping, i.e. smashing bunches of RAW range into a single number OR up or down-pushing the high/low frequencies into frequencies that our eyes can see e.g camera sees infrared, the whole infrared gets smoothed down into red OR camera sees UV, the entire UV gets smooshed up into Violet) cameras sees (RAW) distinction at 440, 441, 442, 443, 444 and 445 nm, BMP gets 440 and 445 nm and that’s it. The others are floored or ceilinged to the closest number (depending on the process). Not at all unlike audio-processing from WAV to MP3
