Being in the middle of the vortex of noise and chaos can be energizing and stimulating, and it can be something of a cheap thrill to try to hold your own in it.

Subvocalization creates enough mental noise that it can hold your attention, but without that it can often be difficult to stick with what you are reading.

Alternatively, increase the sensitivity of the sensor to hand-hold the camera, but be aware at what setting, noise (unattractive speckled patterns) will become a problem with your sensor.
