Adjustment Palette
The right-facing Toolbox icon will open the Adjustment Palette on the right pane of the Image editing Window.
Inside the Adjustment Palette, you can find several image filters to clean up and enhance your images. The Palette will appear slightly differently depending on whether you are on MacPractice builds 7.3 or earlier, or MacPractice Gen 9.
 
MacPractice 7.3 or Earlier

Screen_Shot_2017-05-09_at_2.39.36_PM.png

In MacPractice Builds 7.3 and earlier, all available filters are automatically listed. You can click the triangle drop down to adjust that particular filter, and click the checkbox to enable/disable that particular filter.

MacPractice Gen 9

Screen_Shot_2018-02-16_at_4.54.56_PM.png

In MacPractice Gen 9, you can control which filters appear by clicking the "Add Filter" drop down and selecting which filters you'd like to use. They then appear in the Adjustment Palette. You can then click the X in the upper right corner to close a filter.

If you have multiple filters added, you can also drag and drop them into whichever order you prefer. This may have an impact on how the image is filtered. The filters will be applied in order from top to bottom.

  • Presets: Creates Automatic Adjustments.
  • Image Histogram Equalization: Adjusts contrast using the histogram by spreading the most frequent intensity values. The method is useful in images with backgrounds and foregrounds that are both bright or both dark.
  • Auto Levels: Analyzes a histogram and adjusts the levels to maximize the dynamic range. The Cut Off slider allows adjustment to the grayscale midpoint.
  • Pseudo Median: Reduces noise using possible medians.
  • Median: Reduces the amount of "salt and pepper" noise (where pixels have independently become black or white) by replacing these pixels with the appropriate median intensity.
  • Noise Reduction: Reduces the amount of noise in an image by smoothing graininess.
  • Level: Smooths by harmonizing pixels with neighboring pixels.
  • Sharpness: Reduces blur applied by noise reduction level smoothing.
  • Unsharp Mask: Increases contrast of edges between differently colored pixels.
  • Intensity: Controls magnitude of line edge contrast.
  • Radius: A smaller radius enhances smaller-scale detail.
  • Sharpen Luminance: Increases image detail through a sharpening.
  • Color Control: Controls brightness, saturation and contrast.
  • Saturation: Affects the vividness of a color's hue.
  • Brightness: Controls the lightness from dim to bright.
  • Contrast: Controls the brightness range between light and dark areas.
  • Exposure: Controls the intensity of light.
  • Gamma: Controls the relationship between the brightness of a pixel as it appears on the screen and the numerical value of that pixel.
  • Hue: Controls the tint of the source pixels.
  • Color Map: Transforms colors values using tabled values.
  • Emboss: Filters the image to appear raised or stamped by suppressing internal color and darkening edges.
  • Crop: Removes unwanted areas from an imageThe R button next to each filter is the reset button. The reset button will become active when the filter is enabled. If the reset button is selected, it will return the filter back to its original settings.
  • Histogram: The Histogram box displays a graph that shows the values of the pixels in an image. It plots the number of pixels in the image on the vertical axis with a particular brightness value on the horizontal axis. For more on the importance of the Histogram tool in image editing, please see the Histogram documentation.


Filter Settings Control
Filter Settings can also be found through the Image Preview window by right-clicking on the image within Image Preview. Select the Filters option on the resulting menu. Next, select the specific filter which should be applied to the image.

Screen_Shot_2017-05-09_at_2.40.24_PM.png

When filters are applied through the Image Preview menu itself, the Filter setting selected will open a Control window, where filter settings can be adjusted next to an adjustment preview. Adjustments made with the Control sliders will be reflected in the Control window. The Preview checkbox can also be checked in order to preview the adjustments in the Image Preview menu.

Screen_Shot_2017-05-09_at_2.41.48_PM.png

Filters that are not available to preview using the Control window method include Image Histogram EqualizationInvert ImageMedian, and Sepia Tone. When selected from the Filters list, these filters will automatically be applied.
