How to opacify a photo with GIMP: Have you downloaded some photos on your PC that seem too shiny to you and would like to improve them a little by making them more opaque? Have you taken pictures in public and need a quick and easy tool to obscure the faces of some people portrayed in them? There is only one answer to your needs and it is called GIMP.

GIMP is a free and open source photo editing program compatible with Windows, Mac OS X and Linux. According to many it is the best free alternative to the very expensive Photoshop. Install it now on your computer and find out with me how to opacify a photo with GIMP.

If you want to learn how to opacify a photo with GIMPthe first step you need to take is to open the image you want to make more opaque (via the menu File> Open) and create a duplicate of its background layer by right clicking on it (in the panel Levels located on the right of the screen) and selecting the item Duplicate Layer from the menu that appears.

At this point, select the item Brightness-contrast from the menu Colors of GIMP and lower the contrast so that the image appears very opaque (but not too much). As a guideline, I can tell you that the level of contrast -40 it should be fine, but they are parameters that can vary from photo to photo. In any case, when you are satisfied with the result, click on OK to apply the effect to the image.

Now you need to change the display mode of the level by which you have lowered the contrast, so that it visually blends with the original one making the matte effect more precise and professional. Then click on the drop-down menu Normal located at the top right of the GIMP layers panel and select the item Value from the list that opens. If the result obtained seems too “loaded”, reduce the level of opacity of the layer by moving the lever to the left Opacity located at the top of the layers panel.

At this point, you should be able to get the desired result. For any filings, use the tool Fencing/It burns which allows you to increase or decrease the brightness in limited areas of the image and, when you are satisfied with the work done, save the image by selecting the item Save as from the menu File by GIMP.

You want to dull a photo with GIMP in the sense that you need to obscure the faces of some people portrayed in it? In this case, everything is much simpler. Click on selliptical selection tool present in the toolbar of the program (the one located on the left side of the screen) and draw with the mouse a circle around the face of the person to be obscured.

At this point, select the item Blurs> Gaussian from the menu Filters of GIMP and, in the window that opens, adjust the size of the blur ray to apply to the image. The default 5,0-5,0 px It should be fine. Then click on OK and repeat the operation for all the faces to be opacified.

When you are satisfied with the result, save your “censored” photo by selecting the item Save as from the menu File of GIMP and that’s it. I told you it was a real breeze
