Olympus Dramatic Tone art filter
The techie bit - Dramatic Tone is a Pseudo HDR Processing. The Dramatic Tone Art Filter is simply a very quick 'in-camera' processing to drastically lift up the details in the shadow region, while toning down significantly the brightness in the highlight region. The filter balances up the dark and bright areas, but at a very extreme margin that the image will most likely turn out looking very unnatural. The lighting balance has been heavily manipulated, and the colour saturation has also been boosted, along with the overall contrast of the image. The overall outcome is a very punchy, strong, vividly surreal looking image.
