Description

Changing the resolution, compression and RAW selection on PowerShot G10.

Solution

Changing Resolution / Compression Settings

When pictures are taken as JPEG images, the images are processed inside the camera for optimum image quality, and also compressed to allow a larger number of images to be stored on the memory card. However, the compression process is irreversible, meaning that the original image data cannot be recovered once it has been compressed.

RAW data is the data output by the imaging element and converted to digital data which is recorded as is. This results in images with almost no deterioration in image quality and a higher quality than JPEG images. To shoot in the RAW file format, the camera must be set to a creative mode, either <P>, <Av>, <Tv>, or <M> and the RAW quality option selected as shown below. To view RAW images on a computer, you need to use the supplied software (ZoomBrowser EX/ ImageBrowser), which also lets you broadly adjust images without deterioration in image quality. Using the software's image processing functions, you can take the adjusted image data and convert it a JPEG, TIFF or other type of image in line with your intended use. However, you cannot use direct print or make print (DPOF) settings with images taken in RAW.

Simultaneously Recording RAW and JPEG Images.

On Two images, a RAW image and a JPEG image (Large / Fine), will be recorded with each shot. Since a Large Fine image is also recorded, you can print the image, or view it on a computer, without using the supplied software. images are saved with the same file number to the same folder, and can be distinguished by their file extension. RAW images end with the ".CR2", while JPEGs end with ".JPG"
Off Only RAW images are recorded.
