Ansel always did say, btw, that I was a decent photographer but a HELL of a printer. I'm a lot better at fine-tuning other peoples' images than I am at making my own, in my opinion... So it goes...

Can you explain what you mean by this? Which sliders get adjusted where?

Heck, I don't mind a bit. I got a good score. :)

Not sure I understand how you use a "green filter" but I like the result. The tone separation and range is much better in yours. For the record, there was an extra step for the submitted version not applied to the color one that I posted. I tried autocontrasting the B&W for fun at the last minute just before I saved and thought it was better. I did not realize I'd lost the left side horizon detail until posted. I was going to go back later and correct it but was not done in time to make the deadline.

My print version is better focused on the shrubbery and keeps that left side detail. But if my print version gets rejected again I will try out your method. :)

Another interesting thing I learned in this challenge from David Sidwell is how to use watercolor and crosshatch filters to focus fine detail in an image better. Who wouldda thunk that?

Using Channel Mixer, let the green be the dominant colour in the B/W conversion mix. Exactly how much depends on the actual image. Play with it. People are too locked into red as the dominat colour, based on conventional wisdom. Where there's a lot of foliage or other green, red creates problems.

Now THAT'S interesting to me. You or Sidwell care to elaborate?

And here is the original JPG coverted from RAW uncropped color version

edit: Canoe - the coversion of Dad's Ranch is much more dramatic. Good job.

BTW, I tilted the camera to achieve the "hillside" effect. It just worked out that the tree has a natural twist to the crown that makes it look as if it is growing straight up after the camera is tilted.

Thanks. Now that I put it together that makes sense. When you said "green filter", I was thinking of filtering out green. That didn't seem to jive with what you were saying about the green in the pictures. But I get it now.

As far as "conventional wisdom" goes, I have neither convention nor wisdom in this area. :) I tend to just slide everything around and see what looks good. Its usually just dumb luck if I get something good.

My shot didn't work in B&W but I gave it try. Overall...far better in color.

Without nay further adjustments whatsoever, see the better separation of the tree from the sky, and the somewhat greater luminosity overall?

Robt.

I like that i'll have to give it a go. Thanks

There's mine. I'd love to see a green filter bear, how you do that, and whether it's worth it on beach shots?

Right. Bear in mind that when we're dealing with CAMERAS, a filter passes through whatever color of light it is, and not much else. So a red filter passes through red light, a green filter green light, a blue filter blue light, etc.

So in film, when you use a BLUE filter when shooting B/W, you get much brighter skies, you get proportionally more detail in the shadow areas (they are lit by indirect light, which tends to be blue), and so forth. A RED filter (the traditional "dramatic" landscape filter) will darken skies to near black but sacrifices detail in the shadow areas. Yellow and orange filters split the difference. GREEN filters darken clear skies significantly while giving proportionally much more exposure to foliage, and therefore are of immense value in B/W scenic shots.

When speaking of photoshop B/W conversions, it's useful to speak in terms of "green filters" or "red filters", or whatever, to describe the effects you're seeking in traditional B/W film terms.

Incidentally, Fred Miranda sells a nifty B/W workflow plugin that actually allows you to "select" filters to apply to the color image as if you were shooting the image with a B/W film. You can play with their intensity, and you can jack up or down the dynamic range, as you work.
