WebbBit shifts do two things when activated: Shift all of the bits in an array to the right or left. Write the value of the Source bit to the first bit in the array. What's happening is that when you do your bit shifts, the source bit is still 1 when the BSL is activated, so it writes a "1" into the first bit after each shift. Webb18 dec. 2014 · Of course since you have to write a floating-point color back, you have to reverse the process as well.

WebbBit shift may be useful for 16-bit images that are often dark without a shift. Bayer raw (undemosaiced) processes the image, which consists of four channels (Red, Green (Red row), Blue, and Green (Blue row)— abbreviated R, G (r), B, G (b)) without demosaicing.
