I am slowly pushing in on text with a camera in my composition. I want to give it a kind of random, handheld feel. Not too shaky, but definitely slight variances in the rotation and point of interest to give it a handheld, steadycam look.
I’ve been messing with a wiggle expression and it looks ok, but I was curious if anyone else had other suggestions.

Another good thing to modify if you are using a wiggle() expression are the octaves.
The first two properties supplied to wiggle (frequency and amplitude) are required for the expression to work, the rest of them are optional. If you supply a value for the 3rd property in the wiggle you can increase the number of octaves from the default:
wiggle(1, 10, 3);
The above, for example, will wiggle with a frequency of 1 Hz, an amplitude of 10 but with 3 octaves. This is similar to the “Complexity” of the Fractal Noise effect. It will preserve the overall effect of the wiggle but create additional “sub-wiggles” that add detail.
Here’s an image of a wiggle() with 1 octave:
And here’s a wiggle() with 3 octaves:
Note that both curves follow the same basic path, but the one with 3 octaves has more “sub-wiggles.” If you want to reduce or increase the effect that these additional octaves have you can add a 4th property to wiggle():
wiggle(1, 10, 3, 0.2);
The default value is 0.5. A value of 0.2 would reduce the effect that the additional octaves have on the total wiggle.
