Achromatic pixels

GabrielS. · 01-21-2012, 11:51 AM

Hello to everybody,
i would like to ask here,if somebody knows about a Pentax K-r camera the next issue.
I've noticed that when i take a picture on 10M recorded pixels some achromatic pixels ( two) appears on my foto's.
Does anyone know this kind of issue?
The camera is 2 month old.
One pixel is green and one is red.
I know that the red one is a "hot"pixel..How the achromatic pixel appear it's not totally clear for me.
If i would know ,than probably i would take care in the future.-see the picture bellow
I didn't try yet the pixel mapping.
Thank you in advanced!

Pixel mapping did not solve this problem?

Dane,
I’ve tried the pixel mapping.
At this point i can see a difference.
I must make some macro photo's to see it.
Thank you anyway for your replay.
I appreciate.
