Sharpening

The C2100UZ offers three sharpening levels selectable through the record mode setup menu, as with other Olympus digital cameras we found that changing the sharpening also appears to change the correction curve applied to the image. Thus:

  • Low sharpening = Low sharpening + Low contrast curve
  • Normal sharpening = Normal sharpening + Normal contrast curve
  • Hard sharpening = Hard sharpening + High contrast curve

I personally liked the look of the low sharpening image the most as the flatter contrast curve appears to preserve more image data, but this image will need the most post-processing.

Image "Functions" (post-processing effects)

Just like other Olympus digital cameras the C-2100UZ has the option to apply post-processing filters to the image to simulate black & white, sepia and two text copying modes white board and black board.

Function: Off 
 
Function: Black & White
Function: Sepia Function: White Board
(original was black text on white paper)
 
Function: Black Board
(original was white text on black paper)
 

The White Board and Black Board functions are designed for taking images of black text on white paper or white text on black paper, they seem to work well but I've always wondered why such modes output in JPEG which isn't suited to bitmap files (GIF would have been far better).


Macro Focus

I'm sure the Macro mode on the C2100UZ shouldn't truly be labelled Macro as it's more of a close-up mode, the best frame coverage we could achieve was about three inches with the focal length set to about 1/3 full zoom.


Pop-up Flash

The C-2100UZ has a pop-up flash with a specified range of (at wide) 0.3 - 4.0 m and (at tele) 1.0 - 3.2 m. Other flash features include redeye reduction and the ability to control the flash output by +/-2EV.

Skin tone test, and the camera does well, good balance and not washed out or pale tones. Colour chart (about 5° off axis), again good performance. Full wide "white wall" test from 2m away, coverage here is only average, you can see drop-off in the corners.
Flash compensation -0.3 Flash normal Flash compensation +0.3


Aperture Priority

Aperture priority is where you designate the aperture and the camera calculates the best shutter speed, if the exposure is outside of the cameras range (either over or under exposing) the nearest shutter speed will displayed and the aperture will appear in red on the LCD screen. Used properly Aperture Priority can be invaluable as it has a direct effect on depth of field (the distance in front and behind the focal point which will be in focus when taking the shot).

The C-2100UZ has the following range of apertures:

  • Wide: F2.8, F3.2, F3.5, F4.0, F4.5, F5.0, F5.6, F6.3, F7.0, F8.0
  • Tele: F3.5, F4.0, F4.5, F5.0, F5.6, F6.3, F7.0, F8.0
ISO 100, F2.8, 1/50s ISO 100, F8.0, 1/6s; More depth of field

Other manual features are available: Shutter Priority and Full Manual.
