How to use Neat Image :: Profiling :: Device profiling with Calibration Target

Digital camera profiling

Use the calibration target to build device noise profile(s) for your camera using these steps:

  1. Open the calibration target on the whole screen or print it out on a matte white paper in high quality to avoid printing artifacts:
    - color versions for color printers and displays: 1024x768 / 1280x960 / 1600x1200
    - grayscale versions for black & white printers: 1024x768 / 1280x960 / 1600x1200
  2. Set your camera to a certain shooting mode (ISO level, exposure, etc.) that you want have a profile for
  3. Important: set the focusing system on infinity (you need to get an out of focus image)
  4. Make a shot of the calibration target on the screen (make sure it fills the whole frame, avoid reflections, glare, etc.) or on paper
  5. Bring the test image to Neat Image and build a device noise profile using the Auto Profile with Calibration Target button or Profile | Auto Profile with Calibration Target menu item
  6. Add comments about device mode of the camera to the profile
  7. Save the noise profile to a file with an explanatory name (like C5050Z-ISO100-HQ-SharpNormal-2560x1696.dnp)

    If you build a set of profiles for several camera modes, please also see this section of the user guide.

 

Flatbed scanner profiling

Use the calibration target to build device noise profile(s) for your flatbed scanner:

  1. Print the calibration target on a matte white paper in high quality to avoid printing artifacts:
    - color versions for color printers and displays: 1024x768 / 1280x960 / 1600x1200
    - grayscale versions for black & white printers: 1024x768 / 1280x960 / 1600x1200
    - alternatively, you can use a standard color or grayscale target with uniform featureless patches
  2. Set your scanner to a certain mode (resolution, light level, etc.) that you want have a profile for
  3. If possible set the scanner out of focus (an out of focus scan is preferred for profiling)
  4. Scan the calibration target
  5. Bring the scan to Neat Image and build a device noise profile using the Auto Profile with Calibration Target button or Profile | Auto Profile with Calibration Target menu item
  6. Add comments about device mode of the scanner to the profile
  7. Save the noise profile to a file with an explanatory name (like Epson-2450-4800dpi.dnp)

 

Film scanner profiling

Use the calibration target to build device noise profile(s) for your film scanner:

  1. Open the calibration target on the whole screen or print it out on a matte white paper in high quality to avoid printing artifacts:
    - color versions for color printers and displays: 1024x768 / 1280x960 / 1600x1200
    - grayscale versions for black & white printers: 1024x768 / 1280x960 / 1600x1200
    - alternatively, you can use a standard color or grayscale target with uniform featureless patches
  2. Set your camera to a certain shooting mode (ISO level, exposure, film type, etc.) that you want to build a profile for
  3. Important: set the focusing system on infinity (you need to get an out of focus shot)
  4. Make a shot of the calibration target on the screen (make sure it fills the whole frame, avoid reflections, glare, etc.) or on paper
  5. Develop the slide and put it into the scanner
  6. Set the scanner to a certain mode (resolution, light level, etc.) that you want to build a profile for
  7. Scan the slide
  8. Bring the scan to Neat Image and build a device noise profile using the Auto Profile with Calibration Target button or Profile | Auto Profile with Calibration Target menu item
  9. Add comments about device mode of both camera and scanner to the profile
  10. Save the noise profile to a file with an explanatory name (like Nikon LS4000ED-2700dpi.dnp)
