It works best on RAW files where a temperature has not been embedded into the image. Temperature is used to change the color temperature of an image. We will deal with just the White Balance tools in this article, the others we will look at in some more advanced tutorials. To get to the color tools you need to click the third icon from the left at the top of the Editor Tools. Shadow/Highlight adjustment should be done carefully to avoid halos White Balance Local Contrast boost contrast slightly across the whole image without moving the black and white points out to the edge of the histogram. The Tonal Width sliders define how aggressive the Shadow or Highlight tool is working on an area. The Shadows slider does the same for the dark areas of the image. Sliding Highlights to the right will reduce exposure in the brightest parts of the image without affecting the dark areas. Unlike the general Exposure tools, the Shadow/Highlight tools work only in their specific tonal ranges. That is done by clicking the on switch top left of the tool. Strangely to use the Shadow/Highlight tool you have to switch it on. Like with other editing apps you will get more control over contrast using the Highlight Compression, Black and Shadow Compression tools. However, it keeps both the pure black and pure white points fixed so only changes exposure in the tonal regions of the image.Ĭontrast will push the darker regions out towards the left edge of the histogram and lighter areas towards the right edge of the histogram, posting overall contrast. Lightness works in a similar way to Exposure Compensation in that is lightens or darkens the image. Shadow Compression tempers the effect of the Black tool and is used to lighten or darken the shadow regions of the image. Pushing the Blacks slider too far will clip the shadows Sliding it right will make the blacks darker, sliding left will make them become more grey. The Highlight Compression Threshold tool basically regulates the strength of the Highlight Compression slider.īlack is used to change the density of the darkest parts of the image.
It will raise or lower the density of the highlight areas, allowing you to pull back clipped whites. The Highlight Compression slider is similar to Highlights in Photoshop or Lightroom. Exposure compensation increase or decreases exposure by EV values. Moving to the slider right to 1.00 is the equivalent of adding one stop of exposure. Sliding to the right will increase exposure, to the left reduce it. The Exposure compensation slider simply raises or lowers the overall density of the image. The clipping indicators at the top right of the image window You also have the highly useful histogram to the top left of the screen.
Blown highlights will be shown in black, shadows in white. Like other apps, you can show where there are compressed highlights and crushed shadows To do this, go to the two warning triangles top right of the actual image and set them on. The top section of the editing tools is Exposure. The main exposure tool are top right of the editor window. Don’t worry too much about their complexity, the majority work in much the same way of those in Photoshop, Lightroom or any other image editing software. You will see on the left side of the screen that you have now entered the Editor tab and on the right will be an overly complex looking set of tools. To quickly get to the Image Editor, double-click any image in the file browser. The main tools to get you started with editing an image. These will be Exposure, Shadow and Highlights and White Balance. Today we are going to look at some of the basic editing tools to get you going.
