White? Yellow? (or Brown :))
Gents,
Thanks to Falcon who just did add the perfect example of the difficulties we can have with the "colours" on B&W photos. Taken the same day, at - almost - the same moment from the same position. One with clouds the other without... http://www.me109.info/display.php?a=e&fid=8051 http://www.me109.info/display.php?a=e&fid=4169 Amazingly the octane triangle doesn't seem to display a different tone. Regards, Franck. |

Franek,
This just goes to show how much adjusting the contrast on a photo can effect the image. These are all 9 Staffel--yellow numbers. |

IMHO the contrast comes also from the sun. Planes and shadows are in other positions, so the photos are not takes at the same time. A bit dust in front of the sun, and you got an other contrast in the real life.

Re: White? Yellow? (or Brown :))
U both missed the main point.
Of course the contrast is a little bit different because of the light quantity and quality reflected by the "objects"; and nothing to do with the film and/or photo contrast due to development. The main point here is the "yellow" colour capacity to reflect the sun light. |

Re: White? Yellow? (or Brown :))
My father was a photograph and he explains me that with B&W they often used yellow filter to make clouds more visible...

Yes Olivier
And what happens for yellow colour when using a yellow filter? |

Re: White? Yellow? (or Brown :))
White became bright yellow when yellow stay yellow so I thinks that logically It would became harder to see the differences between white and yellow since the tones are now more similar.
Looking back to your photos: on the one with less visible clouds (so no filter) it is easy to make difference between yellow and white. On the second one, clouds are visible (picture taken with a yellow filter) it is still possible to make the diffrences but it is less important. Indeed, obviously here there is more sun on the second one, enough to get same result as a yellow filter, not used on any of those two pictures imho. |
