The 100 offers four image quality modes and three image sizes. Choosing the right mode and image size is all about finding the right balance between quality and capacity to suit your needs. For a higher image quality the required storage for each image increases, so the camera’s removable media will store fewer photographs for a specific capacity. Smaller image sizes are generally ideal for the web or e-mailing pictures – and here the JPEG compression format can be perfect to keep file sizes down while maintaining good image quality. When you need to retain the highest possible image quality however, the RAW format records the image signal exactly as it’s been captured by the CCD to create ‘digital negatives’. Since the RAW data is uncompressed, there’s none of the compression artefacts commonly associated with JPEG images. RAW files also provide the opportunity to process the image further with minimum degradation.

Relationship between number of images that can be stored, dependent on quality mode/compression ratio/image size

The number of possible photographs remaining is the standard calculated value when using a 512Mb CF card. The number of photographs that can be stored depends on the camera settings and subject.

A major creative advantage offered by digital SLR photography is the ability to control the ‘blurring’ of out-of-focus areas in an image

–such as the foreground or background. Blurring of other parts of the image can make the subject stand out even more, providing a more three-dimensional feel. The large image sensor inside the 100 makes it possible to exercise greater control over blurring using wide aperture settings for a wide range of creative effects.

Comparison of the CCD image sensor size (approximately full size)

A 100 APS-C size = 15.8mm x 23.6mm (approx.)

Typical compact digital cameras (1/2.5 inch) = 4.3 x 5.7mm (approx.)

100 Compact camera

The blurring of out-of-focus areas is the greatest when aperture is open (small ‘f’ value). These photographs were taken using the 100 and a compact digital camera with an open aperture. Because the background of the 100 image is blurred very gently, the in-focus section stands out more effectively.
