Gamma Correction

How to Apply Gamma Correction to a Batch of Images?
1. Open Images
Add one or more image files by selecting them from your hard drive or by drag-and-dropping them into the reaConverter window. They can be any type of image files, because this powerful software supports not only popular extensions, such as JPEG, PNG or WebP, but also RAW, CR3, NEF, ARW, or other less known and rare image files.

2. Add Gamma Correction Action
Go to the Image editing tab, click on Add action, and then Color Adjustments and Gamma Correction.

Here you can easily customize the Gamma values in your image, while checking the result in real time in the Preview section.

3. Save the Result
Review the Saving options you have and decide on the location of your corrected images. Before completing the operation, decide if you want to preserve or change the format of your images.

Finally, click the Convert button and your new images will be available in a few seconds.
