![]() Raw data is so rich that even after cutting big corners your output shines. The explanation for Capture One providing a continuous histogram comes from the simple fact that it has the raw data available. The right (after) screenshot is how the histogram in Photoshop Levels look like the image that I corrected with Levels in Capture One Pro 9. You see a non-continuos histogram with the risk of banding. The left (before) screenshot is from the non-corrected original that got its Levels treatment in Photoshop. Next, I gave the non-corrected image a Levels adjustment in Photoshop to make it similar to the Capture One corrected image. I processed both the non-corrected and corrected with Capture One Levels image to a JPEG and opened them in Photoshop. In the two overlapping screenshots below I show you the Levels tool in Photoshop of the same image of the beach. It relatively increases the number of pixels in your image that belong to the brighter half of the image.ĭragging the mid-tone handle to the right obviously reverses the impact and makes the image darker. By moving it to the left or shadows it shows a positive value. The Mid Tone control effectively rearranges the distribution of levels in your image. You can correct this with the Mid Tone control. Mid ToneĪdjustments of either or both the black and white points affect the overall brightness of the image. See for an explanation in the Capture One or Photoshop section below. The final result is an image that has a longer tone scale as the original, which is more appealing to the eye. Due to the richness of data in the raw file the histogram is still continuous, in contrast to level adjustments in an image editor on your processed TIFF or JPEG file. ![]() The right (after image) now has a white point adjustment. As a result, the light grey parts are now bright up to white, instead of light grey. The left (before) image has no Levels adjustments. Let us look at the effect of the black point adjustment in a low dynamic range image. The screenshot represents the RGB channel tab as you can see at the top. In the screenshot above I marked the black point, mid-tone and white point controls plus the pickers for the black and white points, also known as Shadow Level and Highlight Level pickers in Capture One. As a result, the adjustments will not result in a color shift as might happen when you adjust the color channels individually. This means that adjustments will affect all three channels equally. We start with a brief look at the tool and its controls and demonstrate the effect with a before/after image.Īt the top, you see four tabs – RGB, Red, Green, and Blue. Those are the channels you can select. Let us concentrate on the RGB channel now. ![]() But what does the Levels tool actually do and why is it so important to use this tool in Capture One? We’ll get at the bottom of it here. The Capture One Levels tool is the next stop in your adjustments workflow after you have set exposure and contrast.
