Join Ben Long for an in-depth discussion in this video Customizing JPEG compression, part of Learn Photography: Shooting in Raw Mode.
- JPEG compression is an agreed-upon standard.…The name, JPEGing actually stands for…Joint Photographic Experts Group,…the governing body that specifies the process…of creating and storing a JPEG file.…Because it's an agreed upon standard,…any JPEG image can be read by any JPEG…compliant device or software.…The JPEG specification does allow you to control…some compression parameters…and your camera provides features for customizing…several parts of the raw to JPEG conversion process.…This is a Canon SLR and the features we're about to look at…are available on almost all Canon digital cameras…and similar features will be found on just about…any camera made by any other vendor.…
Earlier, you learned that after demosaicing…and performing color metric adjustment…your camera maps the resulting color data…into a color space.…This space specifies exactly what color each number…in the processed image represents.…These days almost all cameras provide the option…to shoot in one of two color spaces.…sRGB and Adobe RGB.…Adobe RGB is a larger color space.…
In this course, photographer and educator Ben Long shines a light on what it means to shoot in raw—and what it doesn't. Learn the benefits of shooting in raw, learn when your camera's RAW+JPEG mode makes more sense, and get insights into why some people prefer certain raw conversion software over others.
