These two images demonstrate how dramatically shutter speed can change in different lighting conditions when you’re shooting in aperture priority.<\/p>\n

\"black-crowned<\/p>\n

I photographed this juvenile Black-crowned Night Heron about two weeks ago at Bear River MBR. It was early in the morning and it was still somewhat smoky from the fires so the light is low and warm. I was anticipating take-off so I needed enough shutter speed to freeze the\u00a0motion and had to go to ISO 1250 to\u00a0get it. I think it worked out pretty well. I like the pose, the warm light on the bird, the natural setting\u00a0and the action.<\/p>\n

In a recent post <\/a>there was a lot of discussion about using high ISO settings to get sufficient shutter speed and the digital noise that can result. At the request of a reader I plan on addressing that issue fairly soon but this post should demonstrate how\u00a0quickly shutter speed can change in different conditions (when you’re shooting in aperture priority)\u00a0and how much attention the photographer needs to pay to camera settings in the field whenever he\/she has the time to do so.<\/p>\n

Ok, back to this shot for a moment. Notice once again that the light on the setting, background and bird is low and filtered so I needed this high ISO to get sufficient shutter speed for take-off.<\/p>\n

\"black-crowned<\/p>\n

1\/8000, f\/6.3, ISO 1250, Canon 7D Mark II, Canon EF500mm f\/4L IS II USM +1.4 tc, not baited, set up or called in<\/em><\/strong><\/p>\n

Just seconds later another juvenile heron flew by so I quickly raised my lens and fired off a few shots. I had no time to\u00a0adjust my settings so it was one of those “spray and pray” situations. The exposure worked out pretty well (I increased exposure a little in processing) but check out that shutter speed. Since I was still shooting at ISO 1250 and the light was much brighter in the sky than it\u00a0had been\u00a0on the ground\u00a0my shutter speed jumped all the way up to 1\/8000 sec – much, much faster than I needed for the situation and as a result there’s noticeable noise in the background because of the high ISO. It isn’t bad (it would have been worse if the background had been darker or if I had cropped more tightly) but it’s\u00a0more noticeable\u00a0than it needed to be and it would be even more obvious in a large print.<\/p>\n

Another geeky post I know but where would we be as photographers without a little geekiness in our lives…?<\/p>\n
