ASSIGNMENT #8: BRACKETING & LIGHT METERS

​I bracketed.
The assignment: to photograph black against black, black against white, and white against white. While doing this, use an incident light meter and a reflective light meter while ALSO bracketing to see the slight changes. This must be done on film.
Great. I have a black cat and a black background. I too, have a white background and golf whiffle balls my cat loves to chase around (on a white background). 
What could go wrong?
Lots. :-)
Well not lots, but some..
I set up the black background in the living room. (It really is time to get rid of the living room furniture). Upon doing this, my wonderful bae, May, (my cat) gets interested and checks it out. PERFECT. I take the incident light meter reading. Got it. f/4 at 500 shutter. Cool. Click. May is posing and loving it. I bracket to f/5.6 at shutter 350. Click, click. Even greater! My cat is notoriously difficult to photograph. She does not like to look into my camera - ever - and now she was acting like a full out supermodel! Click. I bracket again. f/8, shutter 250, something like that. Fantastic. Click, click, click, click. 
Next, I mix in my other camera with a reflective light meter inside. This one I can see when looking through the viewfinder. Click, click, click, click. May is starting to stray off the background so I offer her some kitty treats. I bracket again. f/11, shutter 150. Click, click. 
Things seem to be going great. 
I decide to take down the black background and put up the white background.
Done.
May LOVES the white background. Full model mode is back. I begin a new roll and take the light reading again and start over f/4, shutter 500. Click, click, click, click, click. I have never been able to get so many photos of my cat!
Three rolls of film later - and an two or so hours in my bathroom/darkroom - I have many, many greatly exposed photos of my cat. 
Fantastic..
Except..I cannot tell any difference between the bracketing changes.
I go into darkroom at PCC and confer with Mike..
Oh crap. I did EQUIVALENCY BRACKETING.. (I read that was what bracketing was..)
He wanted me to do regular bracketing. What is this ?
This is not moving both the aperture and the shutter speed. Move one or the other - 
NOT BOTH.
Gotchya. That was my biggest lesson. 
I learned there is EQUIVALENCY BRACKETING and there is BRACKETING.
