    Where did these stripes come from?

    Can you guys help me here?
    I would like to know what is the cause of the "light rays" in the upper right part of the sky?
    I used a polariser (B+W linear), Lee ND grad and red filter. Lens is 90mm SA.
    Sun was about 90 degrees right.

    Sheet type filters in a Lee holder can produce reflections which can flare especially with a double filter setup like you had going...EC

    I am wondering if I had avoided it if I had shaded the filters from the sun coming from the side.
    @Lachlan: Taco style in Peterson drum. But I do think it is optical.

    Re: Where did these stripes come from?

    I'll go with your thoughts on development not being the issue:

    To me it looks like the Polariser is picking up stress lines on one of the pieces of glass in front of it. I am assuming here that the Polariser is behind at least one of the filters.

    If you have ever looked through Polarising sunglasses whilst driving, you see similar patterns on tempered glass used on car windscreens and windows.

    If this is an ongoing issue, you'll need to do some testing by removing one element of the set up at a time and taking test shots.

    Also, perhaps PM Jay DeFehr in relation to this possibly being a taco issue?

    Nope, the pola was in front (as it should).

    I know of no development defect that could explain this particular pattern. Looks optical to me, too.

    Thanks, Jay.

    I've never Taco'ed, so thought you were the best placed to respond.
