Printing Rewarding Photos from RAW Data
Although it is more usual to compress and save captured images in JPEG format, some digital
cameras allow you to capture images in RAW format.
RAW is a file format designed for computer-based image processing. RAW is supported not only
by digital single-lens reflex cameras but also by some compact digital cameras, and it is quite
common for many professionals and amateurs to capture images in RAW format.
RAW images cannot be printed from photo printing applications in most cases, and an image
processing application is required to adjust white balance, contrast, etc. In addition, RAW images
are larger in terms of the number of recorded pixels than images captured in other formats.
Then why is RAW used to capture images when it requires image processing and increases the
file size?
These are the advantages of capturing images in RAW format.
(1) While compressed data continues to degrade after being corrected on a computer, RAW
data shows almost no degradation.
(2) You can adjust images captured with incorrect exposure, contrast, etc. when processing
them on a computer to match the real scenes.
These two characteristics, no degradation from corrections and the ability to adjust on a
computer to match the real scenes, have made it possible to transform pictures in your mind into
actual images as you wish. This is the main reason for the use of RAW.
It is recommended that you capture images according to your own requirements. For example,
capture snapshots as compressed data and capture photos for an exhibition in RAW format to be
able to adjust them to your satisfaction.
