As headlined here, yesterday was the 66th anniversary of Edwin Land demonstrating the first instant camera - the Polaroid Land Camera - an invention that was significant in the lives of many femulators in the second half of the 20th Century.
A joke: How many femulators does it take to change a light bulb?
Punch line: Three. One to climb the ladder to change the light bulb, one to hold the ladder, and one to take photos of the event.
Before Polaroid, in order to see the photos of the changing of the light bulb, you had to take the film somewhere to be developed, such as a camera store, drug store, etc. These establishments were just middle-men and sent the film out to a photo lab to be developed, but you had to wonder, did Mr. Gower take a peek at the photos when they arrived back from the lab? Did he see you and your "girlfriends" changing that light bulb in all your feminine glory?
You never knew and that lack of knowledge dissuaded many girls from taking photos of their femulations unless they had their own darkroom. (I know of one instance where a femulator built and equipped a darkroom just so she could avoid having her "pretty photos" developed by strangers.)
The Polaroid camera changed all that.
For example, the only photos of my earliest days of femulating were from my first Halloween outing en femme. I did not dare take any photos of my deep-in-the-closet femulations until I obtained a Polaroid SX-70 camera. The camera did not have a self-timer, so I rigged up a mechanical remote control in order to take "pretty pictures" of myself.
And despite their expense, I took a lot of pretty Polaroids. But sadly, many were lost in "The Great Purge of 1983."
And so it goes.
