Offset and the results.
Why?
The problem with any image and trying to make it seamless is getting to the
seams. The seams are the edges of the image. The Offset with the Wrap Around
option activated does some important things for us. First, it offsets or slides
all the pixels over (and/or down) and then wraps the pixels that it slides off
the edge of the canvas around to the other side of the image. This means two
important things. First, after the Offset filter has been applied, the right edge
of the image matches seamlessly to the left edge of the image and the top and
the bottom match as well. Second, it takes the old edges (the old seams) and
puts them right in the middle of the scene where we can deal with them.
Step 4:
Clone Stamp out the seams. The Clone Stamp is an incredibly
powerful tool that allows for interactively painting the pixels from one
part of an image to another. To use it, select it from the Photoshop tool
bar, then hold the Alt (Option on a Mac) and click the area where the pixels
are to be pulled from. Release the Alt and mouse, and then go and paint
where the pixels are to be painted (in this case the seams in the middle of
the image). The results are seen in
