Filter to stop Sun glare

Please help
I have a canon 450d with standard lens. I want to get a filter that will reduce the glare from the sun or bright light. I think it is a Neutral density filter I need to get.
Firstly, is this the right filter and secondly, the prices seem to vary a lot, should I be looking for specific types?

Re: Filter to stop Sun glare

i think maybe you would be better served with a polariser which basically acts like sunglasses for your sensor.

Re: Filter to stop Sun glare

Thanks.
Again there seem to be a lot of polarisers, with varying prices. Can you recommend one or advise me what I should be looking for.

Re: Filter to stop Sun glare

What do you mean by 'the glare from the sun'? Do you mean the contrast between light and dark areas, lens flare, or reflections off water etc

Re: Filter to stop Sun glare

As Roger points out, your question is not clear, but there are two main problems you could be trying to tackle:

Reflected light – this will cause loss of detail in the distance of landscapes or glare from the surface of non metallic materials e.g. water, the sea or a river. To help solve this you need a polarising filter. For DSLRs you need a CIRCULAR not a linear filter.
Note: If the front element of your lens rotates when you focus, using a polarizer can be a pain, as you will need to adjust the filter (by turning it) every time you refocus. A polarizer is a good first purchase.

High Contrast – this is where you have blown (White) skies and good foregrounds or dark foregrounds and good skies. To help with this you can use Neutral Density (ND) Filters. These have a dark and a light area so, put the dark area at the top and it helps to balance out the light from a bright sky. Graduated (grad) filters smooth the transition and are, IMHO, easier to use.
Square or round? Square allow you to move the filter up and down to decrease or increase the effect of a grad ND or to position the change over point of a non grad. Lastly, ND filters have different strengths e.g. 2, 4, 8. the higher the number the darker the effect, so on a bright day you might need a 2 but on a very bright day you might use an 8. Square NDs can be stacked (used together) so a 2 can be used with a 4 to give 6.

Which make and how much to pay? Make is always a matter of opinion and individual choice.
Price: remember this, you are placing this filter in front of your lens, if it is poor quality it will reduce the quality of your images. Stick to names you trust and pay what you can afford.

A last thought. Looked after, filters will last a very long time…..

Just to be a bit piccy here Doug, I think you mean GRADUATED Neutral Density Filters in this instant.

If you do then these graduated ND filters can be choosen to have a sharp transition between the light and dark parts of the filter,these can be useful when taking shots of a setting sun on the horizon.
The other variety of the Graduated ND filter has a "Soft" transition between the light & dark areas of the filter which can be more useful when taking shots of landscape where the sky can be equalised more closely exposed to siut the forground.
Graduated ND filters are available in the common range of 1 to 3 stops difference between the dark and clear areas of the filter. I hope this helps.

Re: Filter to stop Sun glare

Brian
Yes, I intended all my comments on High Contrast to relate to ND filters, so thanks for the added clarification.

John T – Another possibility
If your problem is high contrast you could venture into bracketing, this is where you take multiple shots at different exposures. E.G. take one shot exposed for the foreground and another exposed for the sky. Later you combine these two (or more) images using a photo editor such as Photoshop to give a resulting image of higher dynamic range than would have been possible with a single shot.
Both techniques, filters and bracketing, have pros and cons but it might be another avenue you could explore.

If the problem is reflected light, I do not know of a way to apply a polarising effect once the shot is taken, so you have to use a polarizer, have a look at this link on how to use one.

Thumbs up Re: Filter to stop Sun glare

Doug, that link was very useful.

I want it to reduce sun glare and water reflection.

I will get a polariser, now you have all given me a better idea of what I need.

Thank you all for your advise.

Your welcome, remember For DSLRs you need a CIRCULAR not a linear filter.

Re: Filter to stop Sun glare

Linear polariser will often interfere with the AF beam on dSLRs. CPLs don't!

Re: Filter to stop Sun glare

Also John,
check to see if the Zoom Lens you are using has a "Non Rotating" front lens element where the polorizing filter is mounted or else as you zoom ,the correct setting for minimising reflections will be changed every time you rotate the zoom ring on the lens, so you will have to reset the filter for minum reflections .

Re: Filter to stop Sun glare

Just to add to Markulous comment:
Linear polarizers out date auto focus and are fine when used with manually focused cameras. The majority of auto focus systems use what is called a “beam splitter” to split light between the view finder and the camera’s focusing system. The beam splitter usually employs a linear polarizer, this can be interfered with by the use of a second linear polarizer.
Circular polarizer where designed to overcome this interference and therefore can be used with auto focus cameras

Re: Filter to stop Sun glare

... Ahhh... Gotcha.... Thanks for the explanations there Mark and Doug...
The one I have is linear, it clips in a mount on the front, and I can rotate to suit, but, by that time, I have usually gone manual anyway, as I have been using it for shooting into water mostly (Fish shots) so far...
I havnt tried it yet on normal panoramic shots, so now I know, I will know whats going wrong when I do, and the AF doesnt work...

Erm..... remember what?...

... Reminds me of the tale of the Old Guy in the Nursing home...
One of the health visitors asked him "Do you remember who I am?.."
he replied wryly, ... "If you ask Matron nicely, she'll tell you......"
