In other words, front tilt; just so there is no confusion that a Lens Baby's effect is anything but this combined with a cheap lens. So, use a Lens Baby if you want images that look technically flawed, and use other tilt methods (such as a view camera) if you want more technically sound pix. This is not a judgment against Lens Babies; it is just a description of them compared to other tilt methods.
