Doubling the ISO film speed halves the light quantity recorded by the image sensor.
Light quantity recorded by an image sensor does not change just because the ISO film speed is adjusted. The ISO film speed adjustment on the camera usually changes it at an analog level before digitizing the voltage output from an image sensor.įor example, with the ISO film speed doubled, information is doubled and sampled with an amplifier from the image sensor in the camera.

For more details, please see '10.1.3 Utilizing Difference between ISO Speed Adjustment of Camera and Exposure Bias of SILKYPIX® Developer Studio Pro 6'.ĭepending on the type of camera, developing with a lowered sensitivity of around –0.5 to 1.0EV is possible, and you may be able to save skipped portions, but many cameras cannot save whiteouts with lowered sensitivity at development.ġ0.1.3. When it is so dark that you have to use a slower shutter value or a faster lens, one smart way is to try to use a low shutter speed or aperture value to result in an underexposed image. Photography without Backlight Compensation'. This is considered an effective photographic method for digital photography.Īlso when it is difficult to determine an exact exposure under shooting conditions such as backlight or so on, take a picture with a little underexposed value using the exposure bias.įor more details, please see ' 10.2.1. Increasing sensitivity during raw development normally lessens noise if at around +1.0EV. You can reduce the time and labor when shooting and concentrate more on taking your photograph by performing exposure bias at the time of raw development.įurthermore, exposure bias on the camera often influences the shutter speed, and you must take care concerning camera shake or the subject moving. (*1)Īlso, the appropriate amount of exposure bias must be determined and settings on the camera be changed when performing exposure bias on the camera. There is no information for portions that go over the image sensors dynamic limit, even in RAW data, and there is nothing to retrieve when developing, even when developing with lowered sensitivity. When performing exposure bias on a camera, if the exposure bias is too large, it may not record over exposed highlighted portions. One is that it gives you the ability to control over exposed highlighted portions. However, there are huge merits to exposure bias when developing. Compared to exposure bias on the camera, you may result in a photograph with a bit more noise. Performing exposure bias of +1.0EV at the time of development, development processing is performed with the amount of light recorded in RAW data doubled.Īs a result, both are the same, but they each have their own advantages and disadvantages.Ī drawback of increasing exposure bias when developing is that noise is doubled. On the other hand, exposure bias when developing corrects the exposure recorded in RAW data and develops the photograph.įor example, consider performing exposure bias of +1.0EV.īy performing exposure bias of +1.0EV on a camera, the amount of light recorded on the image sensor is doubled. The exposure bias on cameras slows down shutter speed, opens the aperture and in some cases reduces light with ND filters, thereby changing the amount of light falling on the image sensor.
