Just after a bit of advice for this image. the water looks a tad burnt out - would a polariser help combat this?

P.s. apologies for the border, its for continuity for my website.

Mmm scratchchin

I don't think necessarily so, but it might a bit, on the basis that there's a lot of light coming off that water and we don't know what "orientation" the light is coming back at us. Was it a sunny or a dull day? Looks dull, and I think the most effect would probably be on a sunny day, lots of bright sunshine bouncing around and the polariser might have *some* effect.

Polarisers help by cutting down light which is coming at you with its oscillations at quantum level from all directions and limiting the transmission of only certain of those oscillations.

Hence, for reflective surfaces like surface of water you can cut out reflections and see into the water - try looking at fish in a pool with and without polarised sunglasses.

For foamy white water like this you may have some effect but possibly not much.

Over to someone else's views!


Nice shot though - have you worked from a RAW file - you could do two processes and blend them in Photoshop, or similar, quite easily I would think. But is it all bouncing off the top of the histogram - looks like some detail is in there?

A neutral density filter, or ND filter, would be better smile

Compared to the border the water highlights look light grey to me.

I find water highlights very prone to clip, and I don't think a polariser will help as it'll just act as an ND filter and affect everything. You just need to be mindful of highlights and dial in -EV if required - just like any other high contrast scene.

How was the image converted to B&W? In camera or in photochop? You might try converting using photoshops channel mixer function with the monochrome ticbox checked. Try adjusting the influence of the red channel to increase contrast.

Has the same effect as the red filters we used to use for B&W photography when I was a lad. (basically retarts the greens from the foliage and blues from the skys to darken them wrt everything else, therefore kinda similar to a polariser)
