I have few photos in portrait mode. I wish to make a good wallpaper by removing the background and applying various photoshop techniques.
Can you please suggest me few tutorials or ideas to make a good wallpaper?
A good wallpaper usually has an excellent use of "negative space". What I meant is that it is usually mostly empty and only a small area has any real content in it. The rest are left with lines/colors/empty.
Now, the placement of the main object is also important. The easiest is always to put it in the middle, but depending on the object itself, other placements may yield a more attractive result.
Here are some examples from Smashing Magazine.
