Fujifilm GFX100S: Dark Frame Noise in 14-Bit and 16-Bit
This page looks at dark frame pattern noise at ISO 100, including the individual color channels (ProPhotoRGB color space) with both 14-bit and 16-bit captures.
All cameras have noise in the near-black shadows. One way to assess what gremlins might pop up in real-world images is to look at a dark frame shot with the lens cap on, at a high shutter speed—essentially zero exposure and thus capturing pure noise.
