Lighting 102 Specular light test


80mm zoom with snoot
1/64 for all except the last few ones as noted.
Flash slightly above on camera right







28mm zoom with snoot
darker
But catch light is ~same size because snoot is same






28mm without snoot
catchlight is dimmer now because light is not concentrated as before by the snoot
1/64




Moved flash to the side.
Trying to see if I can get total "external" reflection without transmission thru the glass (i.e: no see through). I didn't get it. I tried angling to make light just hit the surface and bounce off the glass. Seems like I need smaller acute angle of flash to glass.

80mm zoom with snoot


Flash bounced off the ceiling.
80mm zoom with snoot
1/2 power seem 1/64 for others is too weak to bounce off the ceiling and come back.

Catch light is bigger and weaker now that it's not quite noticeable. Bounce off flash is s a bigger light source now.


After this, I don't know what I'm supposed to get and forgot the goal. Gotta read strobist lesson again.
