Bare flash

My raw bare bulb flash in its speedlight mostly unmodified. I shoot both its speedlight head and with the flash bulb head. I also shoot the speedlight with MagMod grid in single and double (2 stacked grids). The bulb created some nice shadows. I suspect this was due to reflection from the wall and ceiling given that I do not have the entire room blacked out. The grids do what is expected and deepen the shadows and focus the light. Note: When I added the modifiers I did not move the light back as this would affect the light I was comparing to.
