Canon Digital Camera Basic Setup – Micro-Photography

Digital Magnification of X-Loupe

 

 

Suggestion: Turn OFF

Explanation:In most cases, the purpose of micro-photography is to take pictures on a specific part of a subject. If AiAF is turned off, the camera will find its focus at a central AF (autofocus) frame, and the best focal distance can be found by simply moving the camera up and down. The camera will automatically find more than one focal positions while AiAF is turned on, but some of the focal positions may not be necessarily wanted. Nevertheless, AiAF can be utilized depends on the practical demand.

Suggestion: Turn OFF

Explanation:AF-assist Beam is located at the front side of the camera, and is used in the dim environment by pressing the shutter halfway. Since AF- assist Beam is blocked by X-Loupe module and X-Loupe is equipped with its own light source, AF-assist Beam should be turn off.

Suggestion: Turn ON

Explanation: For inspection purpose, the bigger digital zoom you use, the less picture quality you get. However, it helps users to view the subject in an easy way. For micro-photography purpose, suggest to use optical zoom only (i.e. 4.0X for IXUS 800IS/950IS) to have better picture quality. Then inspect the digitalized picture with larger magnification on the PC monitor.

Suggestion: Set as desired

Explanation:In some circumstances, it could help to decide the composi- tion of an image with Grid Lines ON.

Suggestion: Hold

Explanation:The micro-photography is utilized on the inspection and photography of a tiny part of a subject; hence, the review of every picture is very important. If the review is not set to Hold, pictures can only be inspected or deleted after switching to Play Mode.
