How to Match the Perspective of an Existing Image in Photoshop
Matching the perspective as you add objects and textures to a Photoshop document has been simplified with the Vanishing Point filter.
Open a building image in Photoshop (File > Open...).
Add a new blank layer above the image layer by clicking the Create New Layer icon. Name the layer, Perspective.
With none of the layers selected, click the Text tool and add some text that will be placed on one of the building faces. Adjust the font, color and size as necessary.
Rasterize the text layer contents by selecting the layer and choosing Layer > Rasterize > Type.
Select the text layer by clicking the layer thumbnail and choosing Select > All (Cmd/a (PC-Ctrl/a)). Copy the selection by choosing Edit > Copy (Cmd/c (PC-Ctrl/c). Hide the Text layer by clicking the layer eye icon.
Select the empty perspective layer and choose Filter > Vanishing Point.
Use the Create Plane tool (c key) to click four corners of the area where the text will be placed. With the plane still selected choose Cmd/ v (PC-Ctrl/ v) to paste the text.
Move the curser over the text and drag it to the plane. Resize if necessary using the Transform tool (t key). Press OK to accept. The perspective text is on the perspective layer.
