The Sidebar gives you access to three important sets of controls. A Histogram is a useful tool for judging exposure and details. Layers lets you work with multiple objects to create a composite image or to isolate effects or textures to their own place. The Tools section gives you precise control over each filter you’ve added to a layer.
- Histogram. While color correcting or adjusting exposure, the histogram can be a great help. This graph illustrates how the pixels in the image are distributed across brightness levels.
- Layers. In Luminar, a layer can contain an image, transparency, and filter information. This allows you to combine (or composite) multiple images into a new image as well as make complex adjustments with maximum flexibility.
- Canvas Tools. Here you can access tools to adjust the contents of a layer. This includes Crop & Rotate, Erase, Clone & Stamp, and Lens & Geometry.
- Tools. The tools you use to edit and enhance your photos are divided into four groups. Essentials, Creative, Portrait, and Professional.
- History. With history, Luminar keeps a list of what you have done to the image since you opened it. These are multiple undos and an easy way to go back in time. Simply click on an earlier History State to revert the photo to that stage of editing. History states are also saved with an image automatically in your Luminar catalog.
