Next look at RGB values or Percentages of the White patch (E1). Adjust the
exposure slider until the white patch lists as approximately 90% in Lightroom,
or about RGB 230, 230, 230 in ACR.
Next check the black (E6). The Blacks adjustment (or in some cases the
Shadows adjustment) is used to set the black value to 4% in Lightroom, or
RGB 10, 10, 10 in ACR. If the value is below this level, it may be best to leave
it as shot, or reshoot with brighter illumination.
In Phocus, put two color indicators on the brightest and darkest patches (E1,
E6) to see the RGB values for each. Now adjust the exposure slider to a white
level of 230. The shadows will be set with the black slider, below the
histogram, to a level of 10.
Now crop and rotate the image to contain only the SpyderCHECKR. Confirm
your selection with a click on the Tool icon. Export the image in TIFF format
and 16-bit color depth. Click on “Open in Image Editor” to open the resulting
file directly from the SpyderCHECKR software.
