## Step 4: Adjust the image to your liking The Settings window on the left lets you adjust the process, method and settings. There are two processes: Tone Mapping, which is applied to the merged 32-bit HDR image, and Exposure Fusion, which combines the source photos directly. The Preview window on the right shows a preview of the final tone mapped image. You can adjust the preview size using the radio buttons on top. It is important to note that the preview is only an approximation -- the final result may slightly differ in the case of the Details Enhancer and Fusion/Adjust methods. The buttons at the bottom of the Settings window let you undo or redo settings, restore the default settings, and load and save presets. You can also access presets directly by clicking on the thumbnails of the Preset Thumbnails panel. The "Built-in" presets show by default. If you have saved custom presets, click on the My presets tab to view their thumbnails as shown on the next page
