Nikon 3D Matrix Metering and Focus Points

Ever wonder why you can get different exposures on the exact same scene with your Nikon camera using 3D Matrix Metering? The meter and AF system are linked in a way that usually produces great results. But for landscape photographers, it can sometimes cause overexposure if you focus on dark parts of the scene, like a shady foreground.

Nikon’s 3D matrix metering is an advanced exposure system that evaluates the entire color image. The same scene can be exposed differently, depending on the location of the active AF point. When the AF point falls on a dark part of the scene, the meter tends to open up the exposure (brighten it). If the AF point is on a bright part of the scene, the camera will expose the scene slightly darker. This difference in exposure can be particularly important to landscape photographers, who usually choose a foreground object for the focus point. If the foreground is relatively dark, the camera will often blow out the sky.

The solution is to first focus on the dark object in the foreground, and then lock focus (I use the AF-On button technique for this). Next, move the active AF point to a bright part of the scene. This allows the meter to bias the exposure to preserve highlight details in the final image.

Look through the viewfinder of the Nikon D4 (video)

Hey friends, here’s a quick video I put together that shows you what it’s like to be behind the wheel of a Nikon D4. I used my little Nikon 1 V1 camera to capture video right through the viewfinder of my D4.

In the viewfinder, you have the option of enabling gridlines. In the D3, you had to buy a separate viewfinder screen. So that’s another welcome improvement. In the video, you’ll see the full viewfinder display readouts, including Metering Mode, Exposure Mode, Shutter Speed, Aperture ISO, and frame counter. You can also see the light meter readout on the right side of the viewfinder window.

The AF system is Nikon’s Multi Cam 3500 FX phase-detection module, with 51 AF points. Each point lights up in red as you activate it.

The D4 is capable of shooting single shots, and at a variety of continuous frame rates. The default rate for Continuous Low (CL) is 6 fps and in Continuous High (CH) you get a whopping 10 frames per second! The D4 will shoot faster than that, but you lose some exposure and focus capability.

The viewfinder blackout in the Nikon D4 is practically nil, meaning you can easily track a moving subject while firing 10 fps bursts.

You can also put the D4 into a “quiet” mode. In this mode, the mirror raises and the camera fires when you press the shutter release, but the mirror won’t drop back down until you release your finger from the shutter button. When it drops down, it does so slowly.

Hope you enjoyed the tour!
