JPEG (Compression and Saving)
Your image is now processed and ready to save. At this point, JPEG compression will be applied, and then your finished, compressed image will be written to your camera’s media card.
The procedure described here is what is required to turn the image data your camera captures into a final image. When you shoot in JPEG mode, all of that processing happens in your camera’s on-board computer. However, your camera may offer an additional option.
RAW Images
If your camera provides a raw mode, you have the option of deferring all the steps described in the previous section.
In raw mode, your camera reads the data off the camera sensor, and writes it to your camera’s storage card.
No processing is performed - Because these files are larger than JPEG files, they’ll consume more space on your card and take longer to write.
To turn a raw file into a usable image, you must run it through a Raw Converter.
Raw shooting offers several advantages over JPEG shooting:
Control conversion. (better image)
Correction of white balance.
Control of processing. (contrast, tone, saturation, sharpening)
Preserve all the color information it captured.
Improving algorithms (As new raw processors come out, you can return to your old raw files and reprocess them)
