I converted a grayscale stepwedge to RGB and noticed that a change in density occurred:
Grayscale 0% changed to 0% RGB, 5% to 4%, 10% to 8%, 20% to 16%, 30% to 24%, 40% to 33%, 50 - 42, 60 - 52, 70-62, 80-72, 90-84, 95-90, 100-100. Converting back to grayscale resulted in the changed values in grayscale. In order to calibrate and apply curves to images is it advisable to print the grayscale image as an RGB file on a desktop printer? Or convert grayscale to RGB and than re adjust the changed values to the original?
