Caught In Passing. March 7, 2012

Passing through the center of little Cummington this evening, a short ways south of here, I spied this wonderful scene of an atypically-colored maple sap bucket hanging from a tap on an atypically-colored sugar maple, and just had to share it with you:

The orange lichen on the tree bark added just the element to get me lying down on the snowmelt-soaked sidewalk, aiming Ollie skyward and muttering as passers-by slowed and shielded their children’s eyes.

Oh, to be a fly on the wall for the ensuing explanations…

I was pleased with this shot from my non-tilt zoom, probably set at around 80mm.  At f/16 the depth of field is acceptable, and at ISO 1000 my D5’s on-board noise reduction was sufficient so that I didn’t have to deal with it in post-processing, so all’s good in the world!

Another excellent picture! crisp, clean, content

Does the ISO 1000 give the ability to keep it in focus?

Diane, ISO is to digital photography as ASA is to film – it’s the speed of the medium. Higher ISO enables shooting in lower light at faster speeds, but it generates “noise,” kind of a graininess. It relates to focus only in that shooting at smaller apertures (larger f-stop numbers) increases depth of field, and higher ISOs allow shooting with smaller apertures. The greater sensor sensitivity registers more light without opening up the aperture, getting more of the subject in focus.

In other words, Yes.

Nicely put. 😀

Thank you for the explanation, I have tried to understand it and think I get it now, you made sense to me! Were you a teacher?

If that wasn’t a big bowl of word salad, there’s no such thing.

And yes, I’ve been a teacher of sorts, though you can’t tell by that mess…
