Hi,


I've been shooting night pics at long exposures and i'm having some problems when i set the shutter speed to 25" or 30" the final picture will have flares..


I'm not sure what it is but there would be light that shows up on the picture. (do not have an example at the moment) My thoughts are that they are the filters I'm using, but the thing is i'm using B+W UV filters i thought that getting B+W will prevent these type of problems.


Does anyone know what the problem is? Should i just remove filters when taking long exposures?


Thanks
