Guys,
A real simple question from a filter novice,
Recently purchased a Lee filter holder (foundation kit) and some Hitech filters including their 10 stopper.
This 10 stopper has a gasket fitted, Which way round should I put the filter into the holder, gasket outwards or inwards facing lens?

Thanks for the help,

Neil
 
Inwards, its stops light leaks between the filter and lens.
 
The reason I asked, is that when applied inwards the gasket does not form a complete seal as it is smaller than the diameter of the wide angle adapter for the filter holder, so a small amount of light can enter through the top and bottom edges where the inner rim of the adapter ring extends beyond the foam gasket, only small gap but certainly gave rise to overexposed images when following standard exposure times.
It really needs the gasket to be right on the outer edge of the filter.

Neil.
 
There are 2 different size gaskets so it depends on the filter holder either LEE or hitech. LEE 1.5mm and hitech 3mm.
 
I have a Lee Big Stopper with the Lee filter holder from the foundation kit.
The gasket is square and doesn't make a perfect seal in the corners.
I worried about it for a while, but as far as I can tell, it isn't affecting my final image.
I've been using it gasket towards the camera, but I can see your logic as to why it might work better the other way around (keep the glass pressed against the holder); to be honest I'd never though of trying it.

I suggest doing your own test by using in bright sunlight and comparing used normally with being shielded by your hands.
And report back :)
 
Remember to cover the viewfinder too, as this may cause over exposure in long exposures.

With both my Canons, letting light in the viewfinder only affects the metering as more light gets onto the metering sensor; it shortens the exposure as the camera thinks the scene is brighter than it really is.

However, letting light into the viewfinder does not seem to affect the actual exposure enough to show on the image, probably because the the mirror is up sealing the viewfinder.
Likewise, metering long exposures in Live View seems to be unaffected by light entering the viewfinder and can be relied on.
