Magenta color tint in high ISO in Nikon D3100

[indrajit]

<p>Hello everybody!<br>

I have a new D3100. It shots fine but there is always a magenta tint in the pictures in the following conditions:</p>

<ul>

<li>High ISO (Hi1 or Hi2) and</li>

<li>Low light</li>

</ul>

<p>I have upgraded the firmware version but the problem still persists. Can somebody help me to solve this problem?</p>

<p>Are you shooting raw?</p>

Is it noticeable over the entire image?

 

What is the RGB measured value?

[indrajit]

<p>Yes, I'm shoting raw.</p>

<p>The tint appears in the darker areas of th picture. And for the RGB values, I will have to check ion the Photoshop (perhaps it cannot be checked in the camera).</p>

<p>Posting an example would help. Sounds like a noise issue to me which would be considered normal IMO when dealing with high ISO and possible underexposure.</p>

[indrajit]

<p>Here is a sample picture. It is taken under these settings:</p>

<ol>

<li>Shutter Speed: 1/30</li>

<li>F-Number:14</li>

<li>Exposure Program: Aperture Priority</li>

<li>Metering Mode: Matrix</li>

<li>Focal Length: 22</li>

<li>Flash: No</li>

<li>Noise Reduction: On</li>

</ol>

<p>I have tried almost all combination of ADL, Noise Reduction etc. but the result is same.</p><div></div>

<p>That's noise you're seeing. Your camera is at ISO 12,800 in that photo. Splotchy color noise, especially reddish and magenta, is unavoidable at extremely high ISO settings.</p>

<p>If you must shoot at high ISOs and you want to remove the noise, you'll need to use noise reduction software in post processing. There are several good third party noise reduction programs. Most offer free trial periods. Try one at a time until you find one that works for you. I like NoiseWare and Noise Ninja, but there are other good programs available.</p>

<p>Well......... Thanks!</p>
