Basic Skills for Micro-Photography
Basic Skills for Micro-Photography
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.
3. Continuous Shooting and Self Timer:
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.
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.
