This is probably an obvious question that I can't figure out but when I take an image capture, Snagit applies some effects by default, like a shadow, a jagged edge, etc... How do I take a shot with no effects?
Change the profile you are using. A lot of the magic of Snagit is in profiles that let a user apply many customized effects. Probably the easiest way to is to reset your preferences. In V13 right click the icon and select Presets > Open Capture Window. Then select the preset you normally use on the left hand side. Last select Edit on the menu and Reset the Settings. Alternatively, use whatever setting you want.
