As you work with an image, the Top Toolbar contains many commands that you’ll frequently use. These are grouped logically for easier use.
These three buttons are used for changing your view of the image size in the canvas. If you go from left to right the buttons do the following.
Magnification Level. The first menu controls the zoom level. Click the dropdown menu to choose from a preset.
Zoom Out. This option reduces the view size of the displayed image. The shortcut is Cmd/Ctrl +- (minus). You can see the current zoom level in the magnification level field.
Zoom In. This option increases the view size of the displayed image. The shortcut is Cmd/Ctrl += (equals).
To see the Original Size press Cmd/Ctrl + 1 to view a 100% magnification showing the pixels in actual size. To Fit to Screen press Cmd/Ctrl + 0 and the image will size itself to the canvas.
These buttons allow you to compare the original image with the original default image, so you can easily compare how your enhancements changes the original image.
Quick Preview. The eyeball icon can quickly toggle between the original image and the enhanced version. Another way to see this change is to use the keyboard shortcut \ (backslash). This allows you to quickly compare the current image with the original. This is the fastest and most convenient mode of comparison.
Compare Button. This button activates a comparison where the image is divided by a vertical strip (“curtain”). The original image (Before) is displayed on the left, and the current result (After) is on the right. This vertical strip can be dragged left or right, so you can view the differences in the picture.
The next two buttons control the Undo command as well as let you view an image’s History. These two buttons give you complete control over reverting to an earlier state of an image.
Undo. The Undo Button (curving left arrow) cancels the last action (for example, changing a slider). This is useful to go back to an earlier step.
History Panel. The History panel will quickly become an essential part of your workflow. It’s here that Luminar Flex 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 early History State to revert the photo to that stage of editing.
