Weird green/blue colour on pictures

[rotisiao]

hi guys..i seem to have a problem with my d40+ nikkor 18-55 dx ed + $15 Hoya UV Filter...it doesnt happen often but it comes up occasionally when i am shooting against bright backlight. What is the problem? I suspect the problem is the filter on the lens but can anyone confirm that for me? They totally ruin the pictures and my beginner skills at ps are unable to salvage them

Get rid of the cheap UV filter.

If you suspect the filter just unscrew and take the pics without. Then you can confirm whether it is the filter or something else.
Whether you NEED a filter or not is a question often debated and there are two major "school of thoughts". You can find links here in the forum as well as on the major review pages in Internet. But one thing remains: if you need a filter get a good one. Brands are Hoya ("Pro1Digital" series), B+W, Tiffen, Rodenstock (in price-increasing order...).
Read more and decide for yourself. At a certain point the price for changing the front element of a lens is equal or less to the price of a filter...

I see you use Auto white balance while your light source is flourescent light. Normally, auto white balance may not work with flourescent light, use flourescent white balance instead.

The problem at hand here is not so much accurate white balance but flaring/ghosting. The source of the problem is the filter. Getting a Hoya UV filter, even one that is single coated, will minimise this.

Something not too expensive but good would be a Hoya Pro1 Digital MC Protector. 52mm goes for about $35. Want something more expednsive then can go for Nikon NC but that I think that's not necessary.

He's already using a Hoya.

The blue colour is likely due to the strong light reflection on non-coated Hoya filter.
But the green skintone probably is auto WB (white balance) problem, use flourescent white balance may help, but still may not be accurate. Try to set manual WB with grey card or on white paper at the same lighting, then reshoot again. For existing photos you can try adjusting WB on Photoshop or other photo editing program.
