How to Use the Inverse Feature in Adobe Photoshop. Use the Inverse feature in Adobe Photoshop to select the area you don't have selected at the time. This can be helpful when you wish to remove or alter the background, but keep the focal point of an image untouched. Using the Inverse feature can be a quick and easy way to select a large area of an image at a time.
Open Adobe Photoshop and open an existing image from your files for you to practice using the inverse feature on.
Use the Lasso tool or Magic Wand to select the object that you want to be the one thing that remains in your document after you apply the Inverse function.
Choose "Inverse" from the "Select" menu to inverse your selection. Now, the rest of the image is selected excluding the original object that you excluded.
Using the option bar at the top of the screen, set your feather to the desired pixel amount between 0 and 250. The higher the number, the more feathered the remaining object will be.
Check the anti-alias option on the option bar to smooth the edges of the inverse selection.
Press your delete key on your keyboard. The background should now be gone and you should only have your original selected object.
When an item is selected in Photoshop, you will see marching ants surrounding the selection. If at anytime you would like to deselect your selection, go to "Select" and then "Deselect." Instead of deleting the background, you could apply a special effect to it.
