I notice when taking shots of landscapes and particularly mountain ranges the photos have a blue tinge to them. What filter do I need to remove this and get a more natural result. Can I achieve the same result in photoshop.

You could use a skylight 1A or even 1B(stronger effect). They have a slight pinkish/faint magenta tint which counteracts the blue. Photoshop is certainly capable of restoring the colour balance within reason

A little tweak in WB or photoshop filters will do the job.

If you shoot films, then those are the filters to get.

As stated above, a UV filter will assist greatly. This is especially useful in the Blue Mountains where the eucalyptus oil creates the blue haze synonymous with the region.

Also you may consider a Polariser (PL) to increase saturation and a Graduated Neutral Density filter, to even out the exposure where you have a bright sky.

Thanks for replies everyone.

I would say a circular polariser is the most important item since the effect it gives can not be reproduced in post processing. There's a good articule on polarisers here.

The effect that a graduated neutral density filter kit gives can be reproduced in Photoshop to some extent by blending exposures, but of course you can still use a GND kit when shooting your scene instead, rather than at your PC.
