[QUOTE="Dave King, post: 40968, member: 3"] 4mesh063 Here's the original photo. [img]http://the-king-family.com/UserPages/DaveKing/elk-snow-orig.jpg[/img] Notice the elk are walking down an slope. The elk I have circled is the one in the smaller picture. Pict #1 is the uncanted picture and the crosshairs are level to the original picture (horizon). Pict #2 IS canted 6 degrees (according to the software I used to adjust the image). The crosshairs are leveled in reference to the elk in pict #2 so they have a 6 degree cant too. This is how a shooter can induce cant without knowing it, as the point of reference becomes the target on a confusing background. *WyoWhisper* picked up on the problem right away.
