Reason: Take IXUS 950IS as example, please refer to the Advanced
Camera User Guide Shooting-Switching between Focusing Mode p.49. In
most cases, the purpose of micro-photography is to take pictures on a
specific part of a subject. During the shooting process, that specific part
is usually moved to the center of the LCD monitor. The camera will only
focus at a central AF (autofocus) frame area when AiAF is turned OFF.
This is convenient for focusing on a specific part of a subject with
greater certainty. Hence, all the user has to do is to move X-Loupe up and
down searching the best working distance and find the best focus. This
focusing mode is more appropriate for micro-photography. If AiAF is
turned ON, X-Loupe might find many auto-focusing spots which are not
necessarily wanted. This situation occurs frequently on taking pictures for
a non-flat subject.
Shooting with the Auto Focus Lock (AF Lock), press the shutter button
halfway and press the button . The AFL icon will display on the right
of camera LCD monitor. The AF lock is convenient because you can let go
of the shutter button. In addition to that, the AF lock is still effective after
the picture is taken and it allows you to take the next picture with the same
focus. It is suitable to used when the X-Loupe is mounted on the stand,
just rotating the knob of the stand and taking the pictures as desired.
Please refer to IXUS 950IS Advanced Camera User Guide P.51and P.52.
4. Zoom:
A subject can be zoomed approximately up to 16X, using the combined
digital (4X) and optical (4X) zoom. When the zoom is set higher than the 4X
optical zoom (where the digital zoom will be used), there might be some
noises and the sawtooth-like stripes showing on the LCD monitor with only
0.23 mega-pixels resolution. It is better to inspect the subject from LCD
monitor when the digital zoom is used. When a picture with good quality is
need, please use only the optical zoom on shooting to get better result.
The Digital Tele-Converter, pp.33~34 in the Advance Camera User Guide
of Canon IXUS950IS, allows users to mimic the effect of telephoto by using
digital zoom. The focal length is 1.6X or 2.0X increased, which is good for
taking pictures both from the short and long distance. The Digital TeleCoverter
can also improve the magnification of X-Loupe. For example, with 300X
objective lens of X-Loupe and 2.0X Digital Tele-converter, the magnifica-
tion is 600X.
To take pictures for a living thing such as insects, it is suggested to use
Continuous Shooting Mode, and then pick the best one from shooting. For
IXUS 950IS, please refer to Advanced Camera User Guide P.37.
Using the Self-Timer in micro-photography can prevent the shaking while
you press the shutter button. Besides 2sec and 10sec Self-Timer, you can
also change the delay time and number of shots (i.e. Customer Timer). For
IXUS 950IS, please refer to Basic Camera User Guide P.16~17.

5. Distance:
In micro-photography, any tiny minor vibration (such as the pulse) can
have some influences on picture quality. To acquire maximum stability, the
working distance of X-Loupe was designed to approach the subject, like
