<Capture and Playback>
What finishing touches setting are included in the Custom Image function?
Select from the following finishing touches:
Bright, Natural, Portrait, Landscape, Vibrant, Muted, Reversal Film and Monochrome.

* The default setting is [Natural].

What is Dynamic Range (D-Range)?
Dynamic range is the ratio that indicates the light level expressed by the CCD sensor pixels from bright areas to dark areas. The larger it is, the better the whole range from dark to bright areas will appear in the picture. By expanding the dynamic range, you can expand the light level expressed by the CCD sensor pixels, making it more difficult for an overexposed area to occur in the image.

*When the dynamic range is expanded for highlights, the lowest-available sensitivity is ISO 400 (or ISO 200 in combination with the sensitivity expansion function).

What is [Slow shutter Speed NR]?
When shooting with a long exposure for extremely dark scene such as night scene or starry sky, image noise (Thermal noise) may become noticeable by produce heat of CCD sensor.
[Slow shutter Speed NR] function can reduce such image noise.

Noise Reduction function can be set ON or OFF in [19.Slow shutter speed NR] in the custom menu.

1: ON:
The camera determines the conditions such as the shutter speed, sensitivity, and internal temperature, and automatically reduces noise as necessary.
Process of Slow shutter speed NR is executed after shooting.
Remaining image storage capacity display (S-LCD) will be brinks during processing Slow shutter speed NR.
Slow shutter speed NR process takes the same time as exposure time.
The camera cannot take next picture until processing is completed.

2: OFF:
When shooting with a long exposure, the camera does not execute noise reduction as much as possible. If some noise is occurred but noise reduction process time is inconvenience, select noise reduction OFF. However, the camera automatically determines sensitivity and internal temperature then noise reduction may be executed forcibly.
What is [High-ISO Noise Reduction]?
When you use digital camera to shoot with high sensitivity setting, image noise (image roughness or unevenness) become noticeable.
645D has Noise Reduction function that you can reduce image noise by using Noise Reduction.

* Images shot with Noise Reduction take longer to save.
* Start sensitivity for [High-ISO Noise Reduction] can be selected by setting. Initial setting is ISO 400.

What is the frame number of the consecutive shooting?
Continuous Shooting --- 1.1frames / sec.
JPEG [40M, starstarstar] / up to 13 frames
RAW [PEF] / up to 13 frames
RAW [DNG] / up to 13 frames
RAW [PEF] + JPEG [40M, starstarstar] / up to 13 frames

It is similar in case of using 1 card slot and 2 card slot.

Can a remote control be used with the 645D?
Yes. The optical remote Control is available.
You can select the remote control shooting mode from [Remote control], [3 sec. delayed release] or [Remote continuous shooting].
What is [Extended Bracketing]?
You can save pictures with three different White Balance, Saturation, Hue, High/Low Key Adjustment, Contrast and Sharpness levels. Three pictures are saved each time the shutter is released.

*When Extended Bracketing is set, the file format is always set to [JPEG] and cannot be changed. You cannot use Extended Bracketing when the file format is set to [RAW].
*Extended Bracketing, DHR (High Dynamic Range) capture and Multi-exposure cannot be used at the same time.

Can Multi-exposure shooting be used with the 645D?
Yes. You can select from 2 to 9 shots.

*Extended Bracketing, DHR (High Dynamic Range) capture and Interval Shooting cannot be used at the same time.

Is there limit on exposure time for Bulb shooting?
No.
What is the "Bright / Dark Area" warning?
When this function is activated, areas in the image that are too bright or too dark and have lost gradation detail will blink on the monitor during playback and instant review.

* Bright portions blink red on the monitor and dark portions blink yellow when [Bright/Dark area] is ON.

What function is "Lens Correction"?
Reduces distortions and lateral chromatic aberrations occurring due to lens properties by digital processing.
