 ## Image Transforms
 
-You'll notice a collapsed group of controls named *Input Transform* in the *INPUT* section under the *Diffraction* panel. RealBloom applies what's called an *Image Transform* on any input image used by any module. An *Image Transform* lets us apply basic corrections and modifications to our input images before feeding them to modules. You'll see *Image Transform* controls in the other module panels as well. Here's what you can generally achieve with an *Image Transform*.
