rob_ned Posted May 5, 2015 Share Posted May 5, 2015 <p>Hi,<br>I have a video camera with a proprietary wide lens that I have changed to a 12 mm MP12 IR lens. This works perfectly in order to take pictures and videos with zoom, however, all pictures have a purple / red discoloration. The White Balance is totally off with this lens. I have tried to tweak the WB, however, the DVR attached to the camera is limited. As soon as there is a slight change in type of light, all colours turn out purple. The original lens is much more forgiving. <br>The original proprietary mini lens has a reddish tint on the glass next to the sensor. This is not the case with my after-market lens. Is this reddish tint some sort of filter? If so, what type? I believe my 12 mm lens has an IR filter. I know the camera has nightmode as well. <br>I'm at a total loss. </p><p>Many thanks for any help.</p> Link to comment Share on other sites More sharing options...
larrydressler Posted May 5, 2015 Share Posted May 5, 2015 <p>Well the opposite of purple is yellow so maybe a yellow #15 for B&W is what you need.</p> Link to comment Share on other sites More sharing options...
glen_h Posted May 9, 2015 Share Posted May 9, 2015 <p>If you are using just IR, then there isn't any "color". But some IR will come through the filters, and that tends to be through the red, though sometimes other filters, too. If you have a choce, it is best to convert the whole image to black and white.</p> -- glen Link to comment Share on other sites More sharing options...
