Red-tailed Hawk as it hunted voles from relatively short power poles in Utah County.\u00a0 Usually when it spotted prey it was far enough away that the bird took off at a normal angle but occasionally the vole would be relatively close to the\u00a0perch so the bird would launch at a steep angle.\u00a0 I think the angle and wing position of such shots adds to the drama.<\/p>\n<p>But with a featureless blue sky as background it begs the question &#8211; &#8220;was this the true angle of the bird?&#8221;.\u00a0 There are no visual cues in the background (such as a horizon line)\u00a0as to what is &#8220;level&#8221; and when one shoots hand-held or from a vehicle window it&#8217;s very easy, even typical, for the camera to be seriously off level as you follow the bird.\u00a0 In cases like this it may even be tempting for the ethics-challenged photographer to artificially exaggerate the angle during processing by using the &#8220;rotate&#8221; tool.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><a href=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2014\/02\/red-tailed-hawk-8599-ron-dudley.jpg\"><img loading=\"lazy\"

style=\"text-align: left;\">Rotation can be tricky.\u00a0 When I posted this image of a Prairie Falcon carrying a Northern Shoveler to an online critique forum, \u00a0one experienced bird photographer dinged me because she said the falcon was tipped too far forward in flight so the image needed counter-clockwise rotation.\u00a0 She failed to notice the horizon line (Great Salt Lake\/sky on a blustery morning &#8211;\u00a0the out of focus\u00a0blobs on the water are whitecaps) and to take into account that when the falcon is hauling a load like this it would affect the angle of attack.<\/p>\n<p style=\"text-align: left;\">For me, images\u00a0that aren&#8217;t properly rotated to level (when there\u00a0are visual cues to level) are seriously\u00a0distracting.\u00a0\u00a0 This is\u00a0an especially common problem for birds on\/in water when there are reflections involved &#8211; possible grist for another post in the future&#8230;<\/p>\n<p style=\"text-align:
