putri Posted October 9, 2005 Share Posted October 9, 2005 if i use a red filter to darken the clouds, will it lose me detail in the green hills and leaves? Link to comment Share on other sites More sharing options...
SCL Posted October 9, 2005 Share Posted October 9, 2005 Red transmits red and blocks blue & green, Green transmits green and blocks blue and red, Blue transmits blue and blocks red and green. It will not affect the details per se, merely the full transmission of the other colors. Look through the filter to see what it does! Link to comment Share on other sites More sharing options...
lex_jenkins Posted October 9, 2005 Share Posted October 9, 2005 Yes. If you need to preserve detail in green foliage because of exposure and development. Be careful to avoid overdevelopment. Better yet, try a deep orange filter. You'll get dramatic skies and overall contrast without struggling to retain desired detail. Link to comment Share on other sites More sharing options...
dalahorse Posted October 9, 2005 Share Posted October 9, 2005 I'd try orange or dark yellow. I don't know anything about medium red (#25), but my dark red (#29) turns green foliage black. Link to comment Share on other sites More sharing options...
SCL Posted October 9, 2005 Share Posted October 9, 2005 Russel - here is an example of the effect Example 1 is the color photo of the scene, Example 2 is the B&W conversion as if Tri-X had shot the picture, Example 3 is what the picture would look like if a red filter was used on the Tri-x. Hope this helps. Link to comment Share on other sites More sharing options...

ronald_moravec1 Posted October 10, 2005 Share Posted October 10, 2005 A red will darken the blue sky and also the green foliage. A green, yellow/green, or poloroid would be better. Maybe a grad density. Link to comment Share on other sites More sharing options...
lex_jenkins Posted October 10, 2005 Share Posted October 10, 2005 A red filter used with most b&w films would produce results more like this than the example Stephen posted. Some work during printing would be needed to produce satisfactory separation in the shadows and lower midtones. A deep orange filter would make this easier.<div></div> Link to comment Share on other sites More sharing options...
james___ Posted October 10, 2005 Share Posted October 10, 2005 In the example number two, all that haze would wash out your sky anyway. The sky would not be as black as you might suspect yet the greens would be very dark indeed. Use a number 58 deep green filter. The sky will go dark and the greens will stay light and full of detail. Any reds will also be dark. To get the sky even darker, use a + development scheme and a polarizer if the sun is at the proper angle. Link to comment Share on other sites More sharing options...
