Photoshop. Different parts of the image have entirely different shadow angles from other parts of the instrument body. The black keys of the keyboard have NO shadows at all. The toggle bar has two shadows, one flash stronger than the other. The ribbon controller has NO shadow that the weaker flash would have to produce on it if it was taken in the same photo. Underneath the white keys you see shadowing that would be produced from a light source pretty nearly directly over head, yet the light sources for other parts of the device obviously are coming from the front right hand side of the keyboard, except for that single lighter shadow on the toggle which appears to be from a light source directly from the camera taking the photo. If you look closely, you can see a shadow cast from that camera angle light source on the lip of the body right at the top of the left most C# key, yet there is no shadow at all on the C key at the extreme left end. And take a look at the lip of the body of the machine at the back of the black keys. At the right of the keyboard, it looks perfectly perpendicular, yet at the right side of the keyboard it appears to slope outwards towards the keys. Look at the LONG shadows on those three dials on the right side of the control body. Yet the rotating wheel virtually has NO shadow at all. A light source that would make the shadow on those dials so stark would wash out any shadow showing underneath the white keys themselves.

Very little attention to details in this fakery..
