What's New in Photoshop 14.2 - Perspective Warp
When you are working with photos, you might find that sometimes, your perspective is off, just a bit. The new Perspective Warp feature in Photoshop CC can help you adjust the perspective of a photo or combine photos with different vanishing points.
Perspective Warp includes two different modes, Layout Mode, and Warp Mode. Layout Mode will allow you to draw a grid to define the perspective of a photo. The finished grid appears as a 3D wireframe. Warp Mode let's you drag the grids you created in Layout Mode to adjust the photo's perspective.
