Basic techniques for better images
Color | On the effects of lighting | |
|
|

The apparent color of the subject is affected by the lighting conditions.

The color tones are adjusted automatically in the auto adjustment mode. However, you can adjust color tones manually with [White Balance] (page 69).
Quality | On “image quality” and “image size” | |
|
|
|
A digital image is made up of a collection of small dots called pixels.
If it contains a large number of pixels, the image becomes large, it takes up more memory, and the image is displayed in fine detail. “Image size” is shown by the number of pixels. Although you cannot see the differences on the screen of the camera, the fine detail and data processing time differ when the image is printed or displayed on a computer screen.
Description of the pixels and the image size
1Image size: 9M
3456 pixels × 2592 pixels = 8,957,952 pixels
2 Image size: VGA
640 pixels × 480 pixels = 307,200 pixels
