Check the final scan:
1. To double check your calibration under the same scanning conditions as the scientists see, scan an image of the 3D standard without the color checker box selected.
...
5. Visually examine each file you just preformed to ensure the colors, neutrals, mid-tone and contrast are true to the real values, and that the scan is free from artifacts. Use the eyedropper tool in photoshop to see the values of pixels (Fig. ## Figure needs to be added).
a) Calibration Check using Image Correction
The following calibration check is designed for technicians to check the SHIL’s calibration. The calibration check is required to be done at the start of every expedition prior to receiving the first core. If adjustments to the calibration are needed, please see the Calibration section below.

Assess the SHIL scan
Prepare the scan to assess the current Image Correction values. If you can achieve a good image by either adjusting, or better yet, keeping the same, values in the following steps you will not need to adjust any of the camera settings in the JAI Camera Set-up window in the calibration instructions below.
NOTE: The Image Correction screen has been updated as of . We are in discussion with Lab Working Group on utilizing the new user interface. The main difference is that we can use colors other than the white, shades of grey and black to determine corrections. For now, continue to select the white, shades of greys and black for image correction calibrations. This user guide is in the process of being updated to reflect the new user interface.
