Saving and Loading Adjustments in Digital Photography

Color adjustments of each photograph in particular are applied individually when the slide, negative or digital photograph have evident unbalances. Unfortunately, the adjustments have to be made with your eye in the image on the monitor, and therefore it is indispensable that is has been properly calibrated. Sometimes the adjustment applied on a photograph can be repeated for others that have been made in similar conditions, and therefore we can save the adjustment made in the first image by clicking the save option in the dialog box, giving it a name and applying it to the rest of the images, opening the new dialog box and pressing load . We can refine the adjustment once applied since the box stays opened.

This option of saving an adjustment lets us easily create a generic correction profile for scanned images as long as we have a gray sample strip: in the dialog boxes of levels and curves we can see three icons of droppers that are used to balance the neutral tones in RGB and CMYK modes and set the

lights and shadows in a Lab mode image and grayscale. If we select the central dropped and click on a neutral zone of the image, the values of red, green and blue of this point are leveled automatically, they neutralize , and the dominant disappears. Therefore, if we scan a sample strip and the resulting image doesn't give us equal proportions when examining a gray point with the info box, we can create a generic adjustment of correction of the scanned images opening the levels box, neutralizing the gray zones with the gray dropper (central) and saving the adjustment with the corresponding command. When we import a scanned image without neutral zones we can eliminate the dominant introduced by the scanner applying the generic adjustment.

The droppers of lights and shadows, besides equaling the proportions of RGB and CMYK channels of the image, set the values of the selected zone on 0 (black dropper) and in 255 (white dropper) by defect, or in the brightness levels we select on the white or black selector which we get by double clicking the corresponding dropper. This is an alternative method to set the lights and shadows for images in Lab color mode or in black and white (grayscale mode); in a RGB or CMYK mode it can only be applied in the case of the shadows and shades being neutral.
