Interesting Leica product announcements today ...
Bruce wrote,on my timestamp of 11/05/2012 5:50 AM:
1. Leica M Monochrom, with 18 MP black and white full frame sensor. No need for a Bayer pattern, no AA filter, no interpolation. Low noise up to ISO 10,000. Hmmm.... I can see already plans for a Photoshop add-on tool to merge together three images taken with R,G,B filters. Kinda like a modern autochrome @ 10000. 2. Leica Summicron 50mm f/2 ASPH. The first 50mm Summicron with an aspherical element. The previous (pre-ASPH) model was one of the sharpest lenses ever made. This one will be even better. Yummy! Pity the price... |

It's easy enough to do without any special tool. I did it testing my theories about what caused certain background effects in the famous Prokudin-Gorsky photos (http://www.loc.gov/exhibits/empire/); my RGB merges are at http://dd-b.net/ddbcms/2001/05/composite-color/. -- David Dyer-Bennet, ; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info |

Leica will be glad if there really are people that stupid, but somehow I doubt that's the target market! 2. Leica Summicron 50mm f/2 ASPH. The first 50mm Summicron with an aspherical element.

And I used to do it for special effects 40 years ago, I sure as hell don't need to do it for normal photo's though. And I'm even more sure I don't need to buy a Mono Leica to take color photo's! :-) Now B&W photography where that 10,000 ISO would be really usable might be another matter however, but only if Canon or Nikon decided to offer a body with such a sensor.

Interesting experiments. Why? I'm puzzled that he didn't realise people were doing this over 50 years ago with multiple exposures on color film using real filters, and the main aim was to get those colored ripples on water, or rainbow colored clouds etc. That's the only reason to do it these days too, not try to eliminate it as David suggests. Obviously Prokudin-Gorsky would have seen this effect immediately and taken steps to avoid it when he didn't want it. However if Prokudin-Gorsky used a 3 lens projector, why could he not use a 3 lens camera and take simultaneous images? Are we sure he didn't? The image of the Nilova Monastery shows no colored ripples on the water or clouds at all, so either it's been very heavily doctored, or he did take simultaneous images. Trevor. |

It is thought Prokudin-Gorsky probably used a personally customized versions of the earlier Adolf Miethe camera produced by Bermpohl Company. http://www.vintagephoto.tv/mb.shtml http://sechtl-vosecek.ucw.cz/en/expozice5.html http://www.vintagephoto.tv/bermpohl_img.shtml http://www.fototv.com/threecolor_photography -- Regards, Savageduck |

As I posted elsewhere, experiments are part of understanding a process. I used to mix my own developers, not to save money, which I didn't, but to learn how the different times and chemicals affected the images. see no reason to trivialize his experiments. -- Peter |

It is thought Prokudin-Gorsky probably used a personally customized versions of the earlier Adolf Miethe camera produced by Bermpohl Company. That camera doesn't take simultaneous images, so the question remains why no color artifacts are visible in the Prokudin-Gorsky photo's. If they have in fact been doctored to the extreme, it should have beeen stated what was done IMO. Trevor. |
