The Exposure adjustment is presented first as it has the greatest impact on all other adjustments. Use exposure in conjunction with the Strength slider in the Smart Editing section. Exposure optimizes the light exposure in every pixel, which corrects the image to emulate what you saw at the time of taking the photo.
Auto Exposure correction
By default, when Exposure is on, so is the Automatic Strength Selection. This means that Radiant Photo will independently look at each photo and suggest a specific amount of exposure correction unique to that photo.
There are three levels of auto exposure correction.
This is useful to help you fine-tune your photos when batch processing or applying presets. If you would like photos to be brighter, for example, then select High. This is why you’ll notice a different exposure value as you load different photos. If you’d like to make a change, you can manually adjust the Exposure slider.
Face Aware Exposure
If you’re correcting images with people in them (or creating a new preset), we suggest you use the Face Aware option. Checking this control enables a more advanced auto-exposure calculation, which automatically produces a more robust correction. This is great for batch processing. It will take into account the exposure of faces that it finds in the photo, as well as the background lighting. This is useful to avoid over or underexposing the people in your photos.
