I like this one in part because of the somewhat twisted body posture &#8211; the hawk was flying to my right but my shutter clicked just as she began a turn to my left so she&#8217;s looking that way with her tail flared just as she was beginning to change direction. I also like the strong hints at habitat and the complementary colors throughout the image.<\/p>\n<p>&nbsp;<\/p>\n<p>Readers will remember my recent issues with soft images on the very cold morning when I photographed a <a href=\"https:\/\/featheredphotography.com\/blog\/2019\/12\/18\/golden-eagle-banking-in-flight-in-warm-light\/\" target=\"_blank\" rel=\"noopener noreferrer\">Golden Eagle in flight<\/a> from inside my warm pickup. Yesterday morning was almost as cold (I saw 13\u00b0 F. not long before this photo was taken) and I sure as hell didn&#8217;t want it to happen again. So as I tried to think of a possible, practical solution some advice from a good friend came to mind. Jim DeWitt (<a href=\"https:\/\/wickershamsconscience.wordpress.com\/\" target=\"_blank\" rel=\"noopener noreferrer\">Wickersham&#8217;s Conscience<\/a> on his blog) made this statement among others when he discussed possible causes of my problem on Facebook:<\/p>\n<ul>\n<li><em>&#8220;Warm air rises and changes the path of the photons, because the index of refraction changes. The warm air in your lens hood can be a really bad offender.&#8221;<\/em><\/li>\n<\/ul>\n<p>So very soon after I arrived at the refuge I decided to remove my lens hood. The result? Nearly all of my photos that should have been sharp actually were!<\/p>\n<p>That&#8217;s far from conclusive evidence that my lens hood was the offender causing my soft shots but on cold mornings I&#8217;ll continue to experiment with having my lens hood on and off and see what happens. At this point I&#8217;m at least slightly encouraged that there&#8217;s a possible, partial solution to my problem.<\/p>\n<p>Thanks Jim.<\/p>\n<p>Ron<\/p>\n<p>&nbsp;<\/p>\n<p><em>Notes:<\/em><\/p>\n<ul>\n<li><em>With the hood removed the overall length of my huge 500mm lens is reduced by about a third. In 12 years of shooting with two different versions of that lens yesterday was the first time I&#8217;d ever shot without the hood attached. It seemed like I was shooting with some little toy lens. It really felt weird.<\/em><\/li>\n<li><em>Shooting without the hood is potentially perilous and expensive. With Canon&#8217;s 500mm lens there&#8217;s no UV filter in front of the big glass in front so there&#8217;s danger of scratching that very expensive piece of glass.<\/em><\/li>\n<li><em>I sure hope I never lose that lens hood. Replacing it would be insanely expensive. Check out the replacement <a href=\"https:\/\/www.bhphotovideo.com\/c\/product\/763754-REG\/Canon_5171b001_ET_138W_II_Lens_Hood.html\/?ap=y&amp;ap=y&amp;smp=y&amp;smp=y&amp;lsft=BI%3A514&amp;gclid=CjwKCAiA__HvBRACEiwAbViuUyVmfpOD0Hfi0JzFGJgMT7JdqTRmudTS7xGrUjjLsC0u7cAUydQB9hoCEycQAvD_BwE\" target=\"_blank\" rel=\"noopener noreferrer\">price<\/a> just for the hood! In case you&#8217;re wondering, the hood contains zero glass &#8211; it&#8217;s just a hood. The reason it&#8217;s so expensive is because it&#8217;s made of magnesium and titanium to save weight.<\/em><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>My photos in the cold yesterday morning were actually sharp!
