Since I have declared the Flashright to be the "winner" over the Lightsphere, just how necessary is it REALLY? Here is a side by side of the Flashright turned to the rear and bare flash facing the rear at about a 45 degree angle. There is some more distinct shadow with the bare flash. If eliminating that small extra shadow is worth the cost of the Flashright is something only you can decide. Keep in mind, the subject is close to a beige door. In a more real life situation. the faint amount of extra shadow created by using the bounced bare flash would never be seen.
