![]() The lower left of the line is the shadow end and the upper right is the highlight end. The tone curve can be changed by placing the cursor on the red line and dragging it up or down from the red line. The bottom left represents the shadows, the middle represents the mid-tones and the top right represents the highlights. It is represented as a straight, diagonal line that you can manipulate to change the tone. Step 2: Image after editing with Auto Tone Correction and Tone CurveĪ tone curve is simply a graphical interface that allows control of the brightness and contrast of the red/green/blue (RGB) color gamut or the individual red, green and blue channels of your image. In this example, I used the Manual control to set the slider slightly lower than the automatic value. This feature is useful to give a flat or under-exposed image a bit more punch. The Auto Tone Correction feature automatically sets the darkest value and the highest value and then uses a slider to adjust the brightness scale of the mid-tones between the two points. Step 1: Image after edit with Auto Tone Correction Always try to always work on a copy of the original file, just in case. I do mine in four quick steps using edits listed above, and simple workflow works for both JPEG and *.orf RAW files, except that with *.orf RAW files you have to add the Monochrome & Sepia edit, or Picture Mode when you are working in RAW Development Mode. The workflow in Image Edit mode on OV3 is fairly straightforward, and the process is nondestructive. You may come across this predicament if you did not take the time to set up your camera properly for monochrome shots, shoot in a high contrast situation, in flat or subdued light, or with clean whites and clean blacks. Ost-processing monochrome or black and white images with edits in Auto Tone Correction, Tone Curve, Brightness, Contrast, and Unsharp Mask is one way to get flat washed-out monochrome images a new lease of life, one which will reflect the way a monochrome image should be presented. ![]() Final image after edits with Auto Tone Correction, Tone Curve, Brightness & Contrast, and Unsharp Mask ![]()
