Title: Do I see RAW, JPEG, or what on my lcd screen?
Post by: dentheman on May 14, 2009, 04:11:46 PM
Hello, I shoot in RAW and JPEG simultaniously (sp?) with my 40D.  My question is:  After taking a shot and viewing it in the LCD, am I viewing it as a RAW image, or has the camera done some processing and showing me a JPEG image?  Thanks.

When you review images on a camera's lcd you are really viewing a small jpeg file that is embedded in the EXIF data.

Is it really small jpeg?
We can zoom it many times larger.

You can think of it as showing a JPEG. You can't display a RAW file so what it displays is effectively a JPEG which corresponds to the RAW file processed with the camera's JPEG settings at the time the shot was taken.

So, it is a raw file processed to meet the camera settings, making it a JPEG.  That's really what any JPEG is, right?  A raw image that has been processed, so it is no longer raw.  Thanks for the inputs, you have answered my question.

Raw image data is not part of the jpeg exif specification.  Raw is not a standard specification as jpeg is so each brand can have their own version and most do. However, both jpeg and raw images include a jpeg exif header file.
