Join Ben Long for an in-depth discussion in this video Correcting and compressing a JPEG, part of Learn Photography: Shooting in Raw Mode.
- There's something odd about your senses.…If you're holding a watermelon…and I hand you a second watermelon of the same weight…you don't actually experience a doubling of weight.…Similarly, if I doubled the amount of light in the room…your eyes don't experience a doubling of illumination.…In other words, your senses don't perceive…increases in stimulation in a linear way.…Instead, the experience increase…and decrease on a curve.…The sensor in you digital camera isn't like this.…It's a linear device.…So if you double the amount of light in a scene,…the sensor records a value that's twice as big.…
This means that what it sees is a little different…than what your eyes see…or what film records.…Film, like your eyes, has a non-linear response to light.…Where your eyes might see this,…your digital camera sees something rather different.…Like this.…In simple terms, your digital camera…just doesn't see as much contrast.…It's images appear flatter.…Our eyes manage to expand contrast in a scene.…This allows us to see more areas in bright highlight…
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.
