In article , Mr. Strat
says... Nice burnt highlights. Glad to see that histogram is doing well for you. If you saw what DSLR images Roger posts to his site you would say "nice burnt shadows". -- Alfred Molon ------------------------------ Olympus 50X0, 7070, 8080, E3X0, E4X0 and E5X0 forum at http://tech.groups.yahoo.com/group/MyOlympus/ http://myolympus.org/ photo sharing site |

All the detail in the foliage at the back is lost - possibly due to the noise reduction. Nice photo, though. Cheers, David |

All the detail in the foliage at the back is lost - possibly due to the noise reduction. Nice photo, though. Cheers, David It is a nice *scene*, but as David notes, the foliage has lost a large amount of detail, and as Mr Strat notes, the highlights are a touch over (although that isn't a big deal).. It is not a technically good image - even at the reduced size, the foliage is clearly (heh!) mush, and detail is completely obliterated in the darker areas (ie almost all of the background). A large print of that image would not be a good idea. Yet a DSLR, competently handled, would have sailed through this test with flying colours. Pun intended.. That type of low-contrast fine detail is a indeed a tough test for digitals - especially small sensored ones - and this one has failed the test. To get better results, you could use a better camera (O:, but if that isn't an option: - shoot in RAW. That way you do not lose any more detail to jpeg compression or noise reduction (depending on the camera), and also you will improve the dynamic range - this scene clearly needs all the dynamic range it can get. - watch your post-proc very carefully. *Selective* noise reduction can help (ie *don't* apply NR to foliage areas!), and also watch any gamma/brightness/contrast adjustments - working in 16-bit, at least initially, may also help. Just trying to help... In a couple of years time, assuming you get good at this imaging stuff, come back and re-visit this image... At the moment I think you may be a little emotionally attached. (O:* (* I'm allowed to be unkind if I put a smiley there - John said.) |

And just to show I'm not *all* mouth... here's an example of an image with a similarly wide (probably wider) contrast range, shot on a similar (but, imo, better) prosumer : http://www.marktphoto.com/examples/pano2_small.jpg (Note -it's a *large* panoramic image - 1.4Mb jpg...) It was shot in RAW, and I (crudely!) used selective noise reduction. Note the foliage detail in the dark areas compared to John's. Yes, it's somewhat *noisy* detail, but it's .. *there*. I am very happy to post a full-resolution crop if anyone wants one. |

All the detail in the foliage at the back is lost - possibly due to the noise reduction. Nice photo, though. Thank you. What this actually shows is the limitation of 8-bit JPEG on the very wide luminance range reducing luminance resolution in shadows, limited depth of field from the wide aperture I used to focus on just the fountain, additional JPEG compression for hosting, and the effect of direct sun on the lens (flare). The image might have been a little better technically if I had used RAW instead of JPEG Fine, but that would be due to the greater luminosity resolution of RAW as compared to 8-bit JPEG and reduced loss of detail from JPEG compression, not noise reduction processing (which was turned down to Low). JPEG Fine did quite well nonetheless. -- Best regards, John Navas Panasonic DMC-FZ8 (and several others) |
