Lately i have been getting a lot of lens flares while shooting towards the sun. They are spoiling what otherwise are good images. I'm using a nikon d80 with a 18-70 lens and an attached hoya pro1d clear protective filter. Is it the filter that causes them? Is it just an issue with this lens or camera? I am also using a lens hood but i still keep getting flares. Is there any other way to avoid them and if not, what is the best way to get rid of them in PP?
