Exposed to Light?

The correct exposure in digital photography!?
In digital photography there are various methods/philosophies about and for the correct exposure.

Method 1 (Exposure to light)

Here you try to capture the bright areas of the image (“devouring“ of light is avoided). The brighter image sections should be exposed for this method. Therefore, depending on the contrast rate, the captured image is more or less dark. This method is comparable to the exposure control in analog reversal film. The reason behind this is that overexposed areas cannot be (or only to a very limited extent) corrected after the image has been captured. A correction of the dark image sections can be done relatively easily in a photo editing program (e.g. Photoshop, Gimp). Disadvantage – By correcting the dark image sections, image noise may become noticeable.


Method 2 (As bright as possible – preventing overexposure)

This method does not directly contradict the method mentioned above; however, the aim is somewhat different in respect to image noise, camera sensitivity and the camera’s effective resolution. Using this method, just like with the method mentioned above, it is advantageous to capture images in RAW format. Here the histogram on the photo review is an extremely valuable tool. For this method, try to move the histogram as far to the right as possible without touching the edge using exposure compensation. If the image appears too bright in the review, this is no deficit. The bright areas of the image have still been stored in this case. The brightness corrector uses the respective RAW converter and sets it to minus. By doing so, not only is the brightness corrected but also image noise can potentially be improved. In doing so, the camera’s sensitivity can artificially be set to below the camera’s lowest possible ISO rate. This method can also be helpful when referring to motion blurring.

 

Note:
Should you be confronted with difficult lighting conditions you should, if possible, use the RAW format when capturing an image. These image files contain more image information than JPG images and are therefore usually much easier to colour correct.
