Some cameras have an auto-exposure bracketing (AEB) feature with a far greater dynamic range than others, from 0.6 at the low end to 18 EV in top professional cameras, As the popularity of this imaging method grows, several camera manufacturers are now offering built-in HDR features. For example, the Pentax K-7 DSLR has an HDR mode that captures an HDR image and outputs (only) a tone mapped JPEG file. The Canon PowerShot G12, Canon PowerShot S95, and Canon PowerShot S100 offer similar features in a smaller format. Nikon's approach is called 'Active D-Lighting' which applies exposure compensation and tone mapping to the image as it comes from the sensor, with the emphasis being on creating a realistic effect. Some smartphones provide HDR modes, and most mobile platforms have apps that provide HDR picture taking.
