I purchased this item: Morris | Soft Box - 15x18" | 32600 | B&H Photo Video I cannot for the life of me figure this thing out. I will admit, I'm a complete idiot when it comes to artificial lighting (I am only accustomed to natural up until this point). I recently purchased a Canon 580ex II and I wanted this softbox because it said it was an "on camera" softbox. I cannot for the life of me figure out how to attach it to my camera's flash. There is a shoe mount on it, but if I mount the flash to the softbox's shoe mount, then how in the world does my flash mount to my camera? And if the flash is not supposed to mount to my camera at this point, then how does the flash know when to "flash"??? You can laugh at me and call me names, but please help me. I'm pretty much desperate at this point and I have nobody to ask. If there is something else I needed to buy, or if it's not intended to even be mounted on my camera please let me know.
