Your bind:... message send looks fine. Are you certain you're binding
to the same CIFilter instance whose state you're logging? (Probably
so, but worth asking.)
Do any suspicious messages appear in the console?

The redrawn image is unaltered, and when I get a description the
filter is still at their default value. I don't actually have
observer code present yet, I just have a button set up to manually
redraw. On the manual redraw, it prints out a description of the
filter it's trying to draw. I throw the slider around and I always
get for the description:
2005-10-21 15:59:23.268 Catalyst[7243] {CIHueAdjust {inputAngle = 0;
inputImage = {CIImage [0 0 22 26]}; }}
2005-10-21 15:59:23.438 Catalyst[7243] {CIHueAdjust {inputAngle = 0;
inputImage = {CIImage [0 0 22 26]}; }}
2005-10-21 15:59:23.640 Catalyst[7243] {CIHueAdjust {inputAngle = 0;
inputImage = {CIImage [0 0 22 26]}; }}
2005-10-21 15:59:24.348 Catalyst[7243] {CIHueAdjust {inputAngle = 0;
inputImage = {CIImage [0 0 22 26]}; }}
2005-10-21 15:59:24.528 Catalyst[7243] {CIHueAdjust {inputAngle = 0;
inputImage = {CIImage [0 0 22 26]}; }}
2005-10-21 15:59:24.708 Catalyst[7243] {CIHueAdjust {inputAngle = 0;
inputImage = {CIImage [0 0 22 26]}; }}
The key that I am trying to bind to is "inputAngle" but inputAngle
is never changing. The binding code with the variables substituted
in is something like:
[newSlider bind:@"value" toObject:(CIHueAdjust here)
withKeyPath:@"inputAngle" options:bindingOptions];

This looks like it should work as written. I have some very
similar code in a project that works fine. In what sense is this
broken? Is it a matter of your image display not refreshing when
you move one of the sliders, or are you seeing the corresponding
attribute unchanged when you read its value back from the filter?
One thing to be sure to do (which might be in code you elided
below) is set the min and max values of the slider to be compatible
with the attribute's recommended range (kCIAttributeSliderMin to
kCIAttributeSliderMax).
