What is the name of the effect used in this photo and how do you apply it to a photo?
As you can see, the nearest servers (which look like cupboards) are somewhat distorted. That is the effect I want to know of.
This effect is called fisheye effect
You can either get this effect by using a fisheye lens or using photoshop. Try googling fisheye effect photoshop. I found there great tutorials there.
