1) It is vital to snap a picture the moment it drifts into focus.
2) Even though this camera has a "shake reducing" tool, it is important to have my arms in a rested
position when I shoot.
3) Simply have a wide plane of the target's surface parallel to the camera's lens, or accept that
getting a clear shot of a steep surface will require more effort and/or time.
As always, this is only a reflection of my own understanding and skills. It worked, though!
