Digital Filters

The K-7 comes with a range of built-in effects called Digital Filters. The ability to apply image effects in-camera is by no means a new one but still fairly uncommon on DSLRs, especially in the semi-pro/pro segments of the market. It has traditionally been a domain of the digital compact camera.

The Digital Filters are set on the INFO screen and applied at the time of exposure (only when shooting JPEG, Digital Filters are deactivated when shooting RAW or RAW+JPEG). Alternatively you can apply them in the Image Adjust menu after shooting (This works both on JPEG and RAW images). Exposure modes and all other parameters can still be chosen freely.

The filters offered are (Parameters in brackets):

  • Toy Camera (Shading level, Blur, Tone break)
  • Monochrome (Filter effect, Toning)*
  • Retro (Toning, Frame composite)
  • Color (Color, Color density)*
  • High Contrast (Intensity)
  • Soft (Intensity, Shadow blur)
  • Extract Color (Color, Color Frequency range)
  • Star Burst (Effect density, Size, Angle)
  • Water Color (Intensity, Saturation)*
  • Fish-eye (Intensity)
  • Pastel (Intensity)*
  • Slim (Intensity)*
  • Miniature (Blurred area)*
  • HDR (Intensity)*
  • Base Parameter Adjustment (Brightness, Saturation, Hue, Contrast, Sharpness)
  • Custom Filter (High contrast, Soft focus, Tone break, Shading type and level, Distortion type and level, Color inversion)

* Only available as a post-shot option through the Image Adjust menu

Some of the filters are purely tonal, affecting only the color and contrast of the shot, others are having a more dramatic effect that goes down to a pixel level. All of them have one or more parameters to play with. The Custom Filter allows you to combine elements of the other filters and can, with a bit of experimentation, create some quite interesting results.

Below are samples of the same shot that has each time been re-saved after applying a Digital Filter in the Image Adjust Menu.
