Photoshop Tutorial: Correcting photos using the Warp tool
A quick, clean mask is applied to the product image. One challenge is presenting a linear image of the book's edge. So, back to the Transform tool Warp for photo correction.
This is the oft debated linearity and nonlinearity vrs. convexity and nonconvexity. I don't pretend to know which side to support. All I know is that I don't want an image of a "bloated" new Planner.
A minor correction to create a more linear image is one of the most practical application of Photoshop CS3's new tool Warp.
Then to finish the image, I include subtle shadows using gradient and effects applied to a few layers.
