i am trying my hand at infrared photography and am using a cokin filter set. with these filters on you can not attach the hood.
i am getting loads of glare in my shots.
anyone know how to overcome this???

It sounds like you'll need to shade your lens and filter somehow with something other than a lens hood. One of the filter makers (Lee?) makes hoods for their filters.
For now, I'd suggest anything that can come between the sun and your camera. Something lightweight and easy would be a paper plate. It's large enough to cast a significant shadow so that you don't have be prescise in your positioning while putting your attention towards your shot. |

Cokin makes a Bellowes-style hood, but is pricey for what it is. If the sun is high, I just use my hand, passing it over the lens just until it comes into view and then pull back a bit.
Or, you could get a Flarebuster. B+H has them for $28.

I would probably get a good size piece of cardboard and bend it to sort of curve, then as telehubbie said, hold it over the lens just out of view.
btw...good luck on the IR, I'm having crappy luck with my camera. This was supposed to be an infrared test but since since I can't get it the way I wanted I just played around and did a tone mapped image.
I'm hoping to do better this weekend. |

First you have to figure out the source of the glare. It could be:
- Light leaks around the filter holder (very possible!)
- Internal reflection between the sensor and lens elements (would appear as a central bright spot, happens with some lenses)
- Lens flare. Again, internal reflections, but from off-axis light. Would appear as haziness or off-axis bright spots/shapes |

im guessing your first option is most likely, as there is clear space between lens and filter with the cokin p-series.
the cokin p-series hood would work, but would make wide angle shots impossible.
i guess i will have to get some dark card and bodge a hood.
i also have a UV filter that screws on. Would taking this off make any difference??
i have also heard that light can enter from the eye piece / view finder.
so i now block this - you can't use it with infrared shots anyway!
cheers for your help kirbic

| A very low-tech solution for glare is to put waxed paper between light source and object. Hope this helps! |
