NIKON D90 LOW NOISE RECIPE

NIKON D90 LOW NOISE RECIPE



1. You will need a manual lens or use the trick I posted earlier.

2. Open the lens to it's widest aperture. This forces the ISO down.

3. Turn on the live view.

4. Zoom completely in with the zoom/qual button.

5. Point the camera at a white card or light colored illuminated object.

6. close the aperture click by click and evaluate the noise. (If it's noisy at the widest aperture, add more light to your scene.)

7. When noise begins to appear, stop and open the aperture until the image is noise free and press the AE-L button.

8. Zoom back out and evaluate your scene.

As soon as you let go of the AE Lock button, the camera takes over again. Did you leave out a step?

Great post, thanks. At step 6, you say "close the aperture click by click and evaluate the noise."

This might confuse users unfamiliar with photo-lingo. If by "close the aperture click by click" you mean stopping-down, you could say "close the aperture stop by stop."

(Of course, that's the only way to close the aperture; maybe it's better to say "pausing at each stop.")

That way newbies may be less likely to think the "clicks" are the "noise" you advise them to judge.

I'd be interested to see how the D90 performs with a green screen behind it.

One note is that if you turn on option b2: easy exposure compensation, then you have a little more flexibility before locking exposure if you only have neutral gray instead of a white card.

First, set the camera to aperture priority. I found that if you set to M, even though the thumb doesn't change the video shutter, it disables the exposure compensation.

Then zoom in (or walk in) and point the camera at your gray card.

Finally, use the thumbwheel to adjust up the number of stops that you want. You could do this with the +/- exposure compensation as well, this is just quicker.

Oh, also make sure that your reference card is reflecting your key light - hold it like a mirror bouncing the main lighting. Also works for presetting white balance.

This would be so great if it was a small video toturial.
It's hard to understand for a beginner.

Is there any chance for this?

You wrote "1. You will need a manual lens or use the trick I posted earlier" Please send or post a link to that post. I want to lock the aperture when using a non-manual lens. Thanks.
