I love playing with the isolation that a thin<\/span> depth of field offers, and\na 340mm<\/span> lens wide open offers a pretty<\/span> darn thin depth of field.<\/p>\n\n

I was at the Kamo River for an Anthony school event, and snapped a few<\/span>\npictures of a hedge<\/span> of long thin branches. The next two<\/span> shots are of pretty\nmuch the same scene from the same location, but the first is focused\nfurther away, while in the second the focus point is closer to the lens...<\/p>\n\n

Both are at f<\/span>\/14 which should generally give a\nfairly<\/span> deep focus area, but with this much zoom you can still get some nice\nisolation.<\/p>\n\n

Here's an amazing example\nof depth-of-field isolation and a moving<\/span> point of focus<\/a>, a short<\/span>\n(90-second) video Zak Braverman made with his video-capable Nikon D90 and a\nZeiss<\/span> 100m f<\/span>\/2. There's not much plot, but it sure\nholds a few<\/span> exciting surprises.<\/p>\n\n

A few more examples from the day...<\/p>\n\n

<\/a>\nD700 + 70-200mm f\/2.8 + 1.7× TC @ 195 mm — 1<\/sup>\/<\/big>500 sec, f<\/span>\/5.6, ISO 360 —\nmap & image data<\/a> — nearby photos<\/a><\/span>\nTea<\/span>\n<\/div>\n\n
<\/a>\nD700 + 70-200mm f\/2.8 + 1.7× TC @ 340 mm — 1<\/sup>\/<\/big>500 sec, f<\/span>\/4.8, ISO 450 —\nmap & image data<\/a> — nearby photos<\/a><\/span>\nBirds<\/span>\nfull frame\n<\/div>\n\n

The depth of field is so thin here there's just no forgiveness. I wanted<\/span> the focus on the center bird's eyes, but I missed<\/span> it by a centimeter<\/span> or so,\nand now you can't even see the bird's eyes in the resulting mush....<\/p>\n\n

<\/a>\n( closeup-crop of the previous photo )<\/span>\nMasked Bandit<\/span>\nstole my focus\n\n<\/div>\n\n

Generally, my standard mode of operation is aperture-priority, where I\nchoose<\/span> what depth of field I want<\/span> and let the camera figure out the rest.\nIf you've seen more than a few<\/span> of my posts, you know how much I tend<\/span> to go\nfor the thin depth of field shots.<\/p>\n\n

Heck, my first post after I got my first digital SLR, when I still<\/span>\ndidn't really know how to use it, includes depth-of-field isolation, like\nthis shot of Anthony looking at fire trucks:<\/p>\n\n

<\/a>\nNikon D200 @ 56 mm — 1<\/sup>\/<\/big>160 sec, f<\/span>\/4.8, ISO 100 —\nfull exif<\/a><\/span>\n( from my January, 2006 post Fire Department Parade, and my new D200 Camera<\/a> )\n<\/div>\n\n

It would have been totally flat if the truck were also in focus.<\/p>\n\n

I must have posted hundreds of examples since then. Heck, this very same\nriverside area was fruitful last spring (A Pleasant<\/span> Day Along the Kamo\nRiver<\/a>), and not long before that I posted<\/span> a few<\/span> shots with Selective Focus<\/a>, but\nwithout much comment.<\/p>\n\n

Here's a great example with an ultra-fast\nlens<\/a> showing Anthony holding a toy<\/span> that's completely blurred even\nthough it's right in front of his face.<\/p>\n\n

Here's one from three yeas ago: Motherhood Knows no\nVacation<\/a>. Well, like I said,<\/span> there must be hundreds. They're sort of\neasy to spot if you browse the “photos appearing in...<\/a>”\npages. It's fun to<\/span> browse in there, if I do<\/span> say so myself :-).<\/p>\n\n\n\n\n\n","protected":false},"excerpt":{"rendered":"
