One of GIMP’s most unpopular features that rivals Photoshop is its ability to apply an X-Ray feature to any image. While clothing and objects in images must be of a bright, thin material, GIMP is able to increase the item’s transparency so that users can actually see through the object that they are looking at. The X-Ray feature can be applied in GIMP by opening the desired image and using the scissors tool to select an object (this can be done by clicking on areas around the object and then clicking the center of the object to edit it). The user then finds the Colors tab on the toolbar and selects Levels. An interface box should appear that allows the user to move sliders back and forth to achieve transparency within the object.
This will allow the user to apply a basic X-ray to an image, but further transparency can be achieved by clicking on Colors and selecting Hue/Saturation. The user can adjust these sliders to make the image clearer. More adjustments can be made in the Brightness/Contrast window in the Colors tab. The user can then make manual adjustments by selecting the Dodge/Burn option and selecting an appropriately sized brush. The Dodge option allows the user to lighten an image while the Burn option allows the user to darken it. The user can go to “Undo History,” select the Scissors, and copy and paste it into the bottom button marked “Select None.” This allows the user to drag the original section over the modified section. The airbrush can then be used (high brush scale/low pressure) to cover the selected area in bright yellow. The user can now select the Layer tab on the toolbar, Transparency, and “Color to Alpha” and choose the same shade of yellow as before (FFF000 works best). The Hues/Saturation option on the Colors tab will now create a much more realistic image when the saturation is set to zero.
