4.4 … use variation with manual exposure (continued)
Step 4: The exposure correction curve is designed according to the image content.
Add as many intermediate point as necessary by just clicking on the corresponding
location on the curve.
In this example, the exposure correction curve is defined as follows:
- section 1: smooth transition from the initial exposure time to 2 f-stops brighter
- section 2: stable exposure time at +2 f-stops
-
section 3: sharp transition From +2 to -1 f-stop the resulting image will be darker
Step 5: When the exposure correction curve is designed, create a new scan to see the
results. If the image is not perfect, fine tune the curve by moving every point separately.
When changing the image angle, the lens or any other parameter
affecting the image format, the correction curve will be reset to flat. It is
then necessary to design a new correction curve.
