Seagull correction

What can be done?

Use this correction after the image has been adjusted with top and bottom bow and keystone. If an “S” curve on top and bottom of the image is visible, proceed to the seagull correction. Due to interaction, it is possible that the top and bottom bow have to be readjusted after adjusting the seagull correction to obtain an improved image. The default value on the bar scale of this correction is 50.
