5. Use a remote cable release or the self timer in addition to a tripod to increase sharpness. This makes such a big different especially when long exposures are required! To increase sharpness even further, engage the camera’s mirror lock-up feature if it comes with one.
6. Use Live View in conjunction with full magnification to manually focus. Thank God for Live View!
7. Shoot waterfalls under overcast conditions. This allows the shutter to remain open for longer in order to achieve that nice silky water movement that you see so often and wonder how it is done! Alternatively, shoot in shutter priority mode (Tv) and dial in a shutter speed of at least 1/15 seconds, or better still use an ND filter to achieve the same effect.
