Adjusting the exposure of photos is crucial for achieving the perfect balance of light and darkness in your images. While the concept of "Ajuste de Exposição" is typically associated with photography and image editing, it is highly relevant to macOS users who frequently work with photos. macOS provides built-in tools that allow users to adjust exposure without needing third-party software. This article will guide you through the steps to adjust exposure using the Photos app on macOS, ensuring your images look their best.

Examples:

1. Using the Photos App on macOS:

   The Photos app on macOS offers a variety of editing tools, including exposure adjustment. Here’s how you can adjust exposure in the Photos app:

   a. Open the Photos app from your Applications folder or Dock.

   b. Select the photo you want to edit.

   c. Click the "Edit" button in the upper-right corner of the window.

   d. In the editing toolbar, click the "Adjust" button (it looks like a dial).

   e. You will see a list of adjustment options. Find "Light" and click the arrow next to it to expand the options.

   f. Adjust the "Exposure" slider to increase or decrease the exposure. Moving the slider to the right will make the image brighter, while moving it to the left will make it darker.

   g. Once you are satisfied with the adjustment, click "Done" to save the changes.

2. Using Preview App:

   The Preview app also allows for some basic image adjustments, including exposure:

   a. Open the image in Preview by double-clicking it or right-clicking and selecting "Open With" > "Preview".

   b. Go to the "Tools" menu and select "Adjust Color".

   c. A panel will appear with various sliders. Adjust the "Exposure" slider to change the exposure of your image.

   d. Once you are happy with the adjustment, close the panel and save the image.

3. Automating Exposure Adjustment with AppleScript:

   If you frequently need to adjust the exposure of images, you can automate the process using AppleScript. Here’s a basic script example:

   tell application "Photos"
       activate
       set selectedPhotos to selection
       repeat with aPhoto in selectedPhotos
           edit aPhoto
           set exposure adjustment to 0.5 -- Adjust this value as needed
           save aPhoto
       end repeat
   end tell

   This script will adjust the exposure of all selected photos in the Photos app. You can modify the exposure adjustment value to suit your needs.
