If you’re new to Lightroom, there are a lot of interface options that you may not realize hide must know and handy program features. In this post, I’ll show you some of the buttons, icons, samplers and switches that a knowledge of Photoshop (at least versions prior to CS4) won’t help you identify or locate.
In the top left corner of the Library and Develop modules you’ll see the Navigator. Beside it are the Fit, Fill, 1:1 and 3:1 options. Click these to resize the image in the current window to various sizes including fitting in the space, filling it and 1:1 and 3:1 resizing options. Other sizing ratios are available from the dropdown list.
The 1:1 ratio is particularly useful when you’re sharpening an image. You may already know that, when you hold the Alt key as you drag on the sharpening sliders the small preview image turns to a grayscale mask showing you the impact of the slider on the image.
If you are in 1:1 preview, the entire image acts as the preview, allowing you to focus in on a much larger area of the image and see the sharpening effect. 3:1 and other larger sizes also work but 1:1 is the minimum size
