Digital Camera Settings
When you capture images with a digital camera, the image quality is significantly affected by the
number of recorded pixels (image size) and the compression rate.
Recorded pixels (image size) refer to the number of pixels comprising an image recorded on a
memory card or other digital media. The higher the value, the higher the resolution and the better
the quality of the image.
However, higher value of the recorded pixels means larger file size and more time spent saving
captured images. Note that if the number of pixels is set to high, you may miss an opportunity to
capture an important moment during sports photography, for example, where continuous
shooting is required.
The compression rate is the rate used to compress image data in JPEG format. With Canon
digital cameras, the compression rate increases depending whether you use SuperFine, Fine, or
Normal. The higher the compression rate, the smaller the file size.
The compression rate also affects the image quality. When the compression rate is increased,
noise caused by tonal variation tends to appear. Many of these noises show up in landscape
photos in which colors of similar tones, such as the blue of the sky and the green of the trees, are
likely to occur. It is recommended that you set the compression rate to low (by selecting
SuperFine) when capturing landscape images.
In other words, you can capture the highest quality images by setting the recorded pixels to the
maximum and by setting the compression rate to the minimum. However, the file size will
increase.
When setting the recorded pixels (image size) and the compression rate, it is important to be
aware of the purpose of printing photos, the paper size and the image quality you want.
When printing on 4" x 6" (10 x 15 cm) size paper, select 1600 x 1200 pixels for the best results.
See the table below to set the number of recorded pixels for the paper on which you are printing.
