Phase One IQ4 Image Quality: Color Bleed (Alabama Hills Sunrise)

Phase One IQ4 150 image quality is top of the heap. But when processing some grossly underexposed images with Adobe Camera Raw, I ran into what I will call here a “color bleed” issue around a broad outer area of the sensor, presumably caused by differential sensor response. Perhaps because of being warmed-up in outer areas by heat-bleed from the electronics.

However, this “color bleed” is a problem that the engineers at PhaseOne have dealt with superbly well, and so this page demonstrates dramatically why PhaseOne CaptureOne Pro is a strikingly superior choice to Adobe Camera Raw, at least for PhaseOne IQ 150 and other PhaseOne backs.
