Banstead Forest Wintery Scenes

Snow fell fairly thickly around the hills here last month, and I got a chance to get out and explore one fine day.

All shot on the K7 with 14mm (approx 21mm equiv on full frame), mostly f6.7 or f8.0, handheld with SR on. As usual initial development in PDCU followed by work in Sagelight 4 & PS Elements with Topaz DeNoise & Detail plugins.




































































There are two shots here that were developed initially in Photomatix Pro HDR software both from 5 individual braketed images. I'd be interested to know if they can be easily spotted!

Thanks for your comments. Nigel.

There are some crackers there. Love the blue skies in the first 5, and the first pic in particular I like very much.

Nice one(s)

Thanks for the comments. You're right with number 6, but number 1 is not HDR, its a single shot. I can see how you would think it could be, as Sagelight's 'smart fill' sliders have brought out the underneaths of the overhanging branches.

Mat, I was pleased also with the blues - the sort of thing I would expect to get with a polarising filter. Well, the Samyang 14mm can't take a polariser, so I use a very effective software polariser in Sagelight. After applying it you can erase the effect from parts of the shot that don't benefit.

Nice shots

I keep changing my mind with the blue in the sky though - I like it then I'm not sure - not a criticism just some how the blue seems unbalanced with he snow on the branches/ ground etc - it may just be the monitor on this laptop though - it ain't great

It may just be my eyeballs not having seen blue sky for so long they need recalibrating

Its an interesting point Stuey - for sure the colour tones appear different on different machines - really nice to me on my new Laptop, but on the old work XP computers they do look 'off', but there's no calibration applied there at all. I have been able to keep consistent colours right through the processing chain, so I guess that's the main thing. Next step would be printing, and so far with foto.com I have been hapy that the colours have been accurate to what I had on screen.

But I have made specific adjustments to colour balance for different parts of the scenes. I think we are all used to seeing a blue cast on snow under this sort of lighting, which is 'unatural' (oh no, not that word again ) - I mean, our eyes correct it to rebalance the snow to pure white. That's what I have done in the pictures, removing the cyan and blue channels and boosting luminance on the snow. And in the skys I have accepted that some ambers will be present from the low sun, and pushed these up accordingly.

Not sure if it works totally - but thats the theory anyway!

This seems to explain it

How did you remove the blue cast from the snow out of interest - it may prove useful if we ever have a sunny day again whilst there is snow on the ground

Thanks Stan! Stuey, in answer to your question about the blue cast - nothing too complex.

I leave this sort of thing to the end (in case it results any loss of detail), then in PS Elements I make a selection (usually just the quick selection brush - then refine edge), so all the snow parts, then open up Hue/Saturation - use the dropdown to choose the cyan channel and pull the saturation slider down. As well as removing the blue case this has the effect of lowering the light intensity, so you need a compensating right movement on the luminance slider to restore the lost lightness. Then repeat the process using the blue channel from the dropdown, and voila!, lovely white snow

Thanks for that I will try to commit that to memory and then return to the thread when I try it as I will inevitably have forgotten
