I've only used one color background, for my product photography, for a long time: Savage Studio Gray. It showed as not quite white and not really gray. I've finally added some new colors. I tried the Super Black which I liked. Now I've added Super White and Thunder Gray. This is a test to see how something looks with each backgound. I am particularly intersested in the Thunder Gray for portraits, my next test. Then I can start playing with spots of light and color. I have a Flickr set with larger images: Seamless background paper test.

The Canon Model V flash gun folded up. The Canon P rangefinder has a unique attachment. The flash pc sync socket is on the end of the top of the camera with kind of a bayonet mount around it. The Canon Model V slides over it and a ring locks it. Very solid and it angles the flash to the side and up. Flash bulbs may be obsolete but electronic flashes are mere wimps compared to the common 25b press bulb. The average on-camera flashes for point and shoots have a guide number of around 14. My Vivitar 285 is 110, I think. My Metz 45 CL1 is around 150. The guide number for this little blue bulb is around 200. I have a battery on the way. I'm looking forward to using it. I've used them on my Brownie Hawkey Flash Model. I love it when people start screaming "I can't see! I can't see!" followed by "What is that smell?"
