Noise Management

Noise is always a problem with digital photography. Olympus offers different solutions to minimise the noise.
 
Noise reduction
Fixed pattern noise is the type that always appears on same pixels with long exposure shots. It can be eliminated to a huge extent with the Noise Reduction mode.

How it works: Two images are taken – a regular shot and another with the same exposure settings but where the shutter is kept closed. The pure black image includes all likely noise in the same positions as on the real image. The noise detected in the ‘dark’ image is then removed from the proper image file.
For the right image the Anti-noise reduction was switched on.
 
  
 
Noise filter

The Olympus E-1 incorporates an additional anti-noise feature, the noise filter.

Random pattern noise can occur, for example, when shooting with a high ISO setting and may also appear in dark areas of a photo. By intelligently analysing and processing the image information, the Noise Cancellation function helps remove some of this noise, smoothing the contours of the objects in the photo. Its benefits are particularly noticeable in lower contrast areas of the shot, such as a blue sky or person’s skin.


Here are frames taken without and with noise filter.

Colour adjustment

The Olympus E-System features a number of modes that let you adjust the colour of the image before capture. Colour Spacing helps optimise the photos for use with certain products, like printers or monitors. The colour saturation settings enable on-the-spot enhancement of colour tones.
 
Colour spacing

There are two colour space settings.
sRGB ensures images are saved with a standard colour scope used by the Windows operating system and similar to those of most ink-jet systems.

E.g. offset printing can be done with Adobe RGB as it supports this colour range and is therefore particularly suited to such applications.

 
Colour saturation

Adjustment modes are on hand for when you want to experiment or obtain special effects on location and not wait until you get back to your computer.
There are five levels which can be chosen for general colour saturation.

White Balance

The E-System offers an array of precision white balance settings to give you the versatility to shoot in a wide variety of light temperatures.
 
White balance pre-sets
Besides the auto setting, you can also select different white balance modes, extending from 3000K to 7500K plus manual settings.
 
Auto bracketing - choose your best photo
The camera takes a single shot and creates three different files, each processed at a slightly different white balance setting. You can select between increments of 5, 10 or 15 mired (Micro Reciprocal Degrees). The bracketing function enables you to choose the frame that has the best white balance.
 
One-touch calibration
For an even more exact white balance than the pre-sets can deliver, you may use the one-touch white balance. This is sensitive to temperatures from 2000K to 10000K and the setting can be stored in memory (E-1 = 4 settings/ E-300 = 1 setting).
 
Compensation
Fine-tuning is possible with the white balance compensation feature. You can increase or decrease the setting of the camera by 14 mired (Micro Reciprocal Degrees) in 2 mired steps in the auto or pre-set modes.
 
Special auto white balance with the E-1
The camera’s advanced auto white balance uses a hybrid metering system. Readings are taken with a detecting sensor on the camera’s front as well as 'Through The Lens' (TTL) using the CCD. This dual system ensures precision measurements under most conditions.

Shutter

Ranging from 1/4000 sec. to 2 sec. in the program, aperture or shutter modes and up to 30/60 sec (E-300/E-1 & E-500). in the manual mode, the Olympus E-Systems ’s focal plane shutter provides the versatility necessary for a wide variety of subjects, effects and situations. Exposures up to 8 minutes long may be taken in bulb mode.


The flash synchronisation of the Olympus E-System is outstanding. It offers particular flexibility when working with an external flash system. With the FL-36/ FL-50 flash synchronisation at all shutter speeds is possible – even 1/4000 sec.

 
Exposures can be triggered using the soft-touch electromagnetic release, self-timer or remote control. Using the anti-shock function, the shutter releases from between 1 and 30 seconds after the quick return mirror has moved up. In this way, any slight vibrations can be avoided.
A self timer mode can be chosen as well as a remote control for shutter release.

Focusing

For accurate focusing, three separate modes are available:
  • Single AF
  • Continuous AF
  • Manual focus
The system uses three user selectable or automatic AF points (left, centre, right).
 
A dedicated AF system
The autofocus sensor has a totally new design to combine speed with accuracy.
Readings are taken Through The Lens (TTL) using a phase difference detection method. To enable fast processing, the signal is digitised into 16 bit data and processed by an ASIC chip. The dedicated focusing motor provides quick focusing with the highest precision. (Accuracy needs to be 5 times higher than with conventional 35mm systems.)
 
Taking readings from either the three points shown in the frame or from one of these selected manually, the Olympus E-System keeps images sharp. The focus setting may be locked by pressing the AF lock button.
In low contrast conditions, a 3-beam AF support lamp supplies the necessary light to aid focusing on objects up to 7 metres away in the E-1. The E-300 uses pre fired flash for correct metering.
The AF system has a working range of 0 to 19 EV (ISO 100). By selecting the release priority, the camera takes the shot even if it does not have the subject in focus.

 

AF engine

 
Continuous AF - For fast shooting
For keeping fast-moving subjects in focus, the Olympus E-System features a continuous AF mode. Here, the focus is constantly readjusted as necessary.
 
Manual Focus
The focus is adjusted manually using the focusing ring.The Olympus E-System also permits the combination of automatic and manual focus. When taking individual shots, you can make fine manual adjustments to the focus after the autofocus has been carried out.

Exposure Control

A range of exposure metering and adjustment options are available to support you in capturing well-balanced images in virtually all situations.
 
Exposure modes
There are four exposure modes: Program, Aperture, Shutter and Manual priority. In the ‘Program’ mode, the camera sets the optimum aperture value and shutter speed automatically based on the readings taken. A program shift is possible, while keeping the correct EV to meet requirements on aperture or speed.
 

‘Aperture Priority’ lets you choose the aperture and then automatically selects the best shutter speed. In ‘Shutter priority’, you determine the shutter speed and the camera sets the optimum aperture. In both of these modes, by using the preview button, you can see the depth of field in the viewfinder.
Naturally, full manual control of the aperture and exposure time is possible.

The E-300/ E-500 features additional scene programmes for easy access, automatic exposure and image parameter setting. Just choose one and you will be guided on the LCD how to use it.

 

 

Metering methods
Digital ESP exposure metering
The camera measures the light levels and calculates the differences between the various areas of the frame – both in the centre and around. This method is recommended for most standard situations, but is also capable of handling others, e.g. backlit situations.
 
Centre-weighted metering
Unlike the digital ESP mode, the centre-weighted metering method places more importance on readings from the centre of the frame. Here, approximately 6% in the centre of the total area provides the majority of exposure information, but a few readings are also taken from outside the centre to provide an average measurement. Consequently, this mode is recommended when you want to prevent the background affecting the exposure value.
 
Spot metering
Taking readings from approximately 2% of the frame in its centre, you can be sure you have metered correctly for a very precise section of your photograph. Additionally, the E-500 incorporates highlight and shadow basis metering for enhanced preciseness.
 
AEL lock button

With the E-1/E-300 the exposure settings as well as the AF settings can be locked with a press of the AEL button according to the setting made . You are then free to re-frame the shot. With the E-300 you can preset a special metering method for easy access.

 
Exposure compensation
In some situations one may get better results if the exposure values are refined manually. For fine-tuning the exposure settings, exposure compensation of +/- 5 EV in 1/3, 1/2 or 1 steps is possible. This adjustment is kept for subsequent shots.
 
Exposure bracketing

Using the bracketing function, the camera shoots a number of pictures at different exposure values for each frame. In situations where correct exposure might be difficult to obtain, bracketing gives you more than one exposure so that you can choose the best result. It is possible to shoot 3 or 5 pictures of the scene in sequential shooting, but the shots can also be taken manually.

The bracketing function can be used in all dial exposure modes. Used in the program mode it changes aperture and speed, whilst in the aperture or shutter priority modes the pre-set values are kept and only the counter value changes. In the manual mode the priority lies on the aperture, so that the shutter speed is modified.
 
The compensation values can be adjusted in 1/3, 1/2 or 1 EV increments.
 
Working range
Thanks to the wide working range, accurate exposure readings can be taken even in darker situations, like twilight. ESP and centre-weighted metering can handle light levels between 2 EV and 20 EV (E-1/ E-500 between 1EV and 20 EV), while spot metering allows light intensity ranging from 3 EV to 17 EV (50mm f.2, ISO100).
