There are a ton of ways to approach editing an image, with different methods having their own pros and cons. One method involves using Smart Objects, and this helpful video tutorial will guide through editing landscape images with them and show you why they are so useful.
Coming to you from Michael Shainblum, this great video tutorial will show you how to use Photoshop’s Smart Objects to edit landscape images. If you have not seen them before, a Smart Object is a special sort of layer that uses data from a raster or vector image without discarding the original information. This allows you to do things like apply resizing and geometric transformations nondestructively or use things like filters while retaining the ability to undo or go back and change their settings whenever you would like, which is particularly useful if you are applying a lot of overlapping adjustments that work in tandem to create the final image. On the other hand, you can’t do anything that affects pixel-level data on a Smart Object (such as using the Clone Stamp); you would have to rasterize the layer first. Check out the video above to see them in action while Shainblum edits.
