Here is the second part of our article on graduated ND (Neutral Density) filters.
Depending on how well calibrated your monitor is, there should be a difference in the images displayed below.
The exposure for the images were identical and the camera was used on ‘Daylight’ for the white balance setting, unless otherwise stated, we took the initial meter reading then put the camera into manual mode.
Without filter
With filter
Filter position adjusted to bias sky
Auto exposure
Auto white balance
Conclusion:
Positioning of the filter will make a considerable difference, as will the strength of filter, there is a degree of trial and error involved, but the results are worth it.
Putting the camera onto auto exposure reduces the effect of the filter, better as stated previously is to take a reading before using the filter and using the camera in manual exposure with the same settings.
Also notice what happens when the camera is set to AWB (Auto white balance), the camera tries to compensate for any colour bias in the filter resulting in a warmer foreground.
