camera with high dynamic range ??
I would like to buy a compact or pocketable P&S camera. It should have
a high sensitivity, so that I could shoot the night scenes in the city with excellent quality. I heard that FujiFilm FinePix F10/F11/F30 has a good CCD sensor allowing to shoot in dark... however, I never held it in my hands and I read the reviews that its sensitivity is not really that high, and the image has a "watercolor" quality in it. Besides, I do not think that its lens is sharp enough as say Panasonic FZ30 or LX1. I presume that the camera with the desired qualities should have larger pixels, and thus a larger sensor... which means the lens should be big, too... and I want a pocketable camera. If there is no such camera, then I want a camera with a high dynamic range. I want to shoot both bright sun-lit sceneces and to resolve details in shadows, in the same picture. Again... I am not aware of such a camera. Can you advise any ? Thanks. ... |

The theory says that CMOS sensors would be best for you, because they have an incredibly large contrast range up to 6 orders of magnitude. I don't know about consumer cameras with CMOS sensors though. Hans-Georg -- No mail, please. |

No, high sensitivity will just give you lots of noise. For quality stick to the lowest ISO with a long exposure. I heard that FujiFilm FinePix F10/F11/F30 has a good CCD sensor allowing to shoot in dark... however, I never held it in my hands and I read the reviews that its sensitivity is not really that high, and the image has a "watercolor" quality in it. Sounds like overly-agressive noise reduction. Avoid it. Besides, I do not think that its lens is sharp enough as say Panasonic FZ30 or LX1.

You convert the RAW image into a 16 bit per channel image then you can lighten the shadows to extract the details you want. The LX1 is an excellent choice of camera which is both pocketable and has RAW mode. It also has a very good lens, but is a little noisier than other cameras. This is probably due to less aggressive noise reduction - you can always add your own later, but you can't take it away, so arguably it's a good thing. One disadvantage is that the RAW files are exceedingly large, 16MB per picture, only 52 per 1GB card. Still a good choice though, if you buy plenty of memory cards to go with it! Paul |

I measured 10-11 stops with my G3 a few years ago. The darkest few stops look a bit nasty, but they're quite acceptable provided you don't lighten the darkest shadows too much. You can always take multiple exposures and layer mask them if you want the best quality. Paul |

Michna says... The theory says that CMOS sensors would be best for you, because they have an incredibly large contrast range up to 6 orders of magnitude. That is true only for the non-integrative type, which has a logarithmic response, but suffers from high noise levels (because you don't integrate over time - exposure time is basically 0). All other CMOS sensors which integrate the light over time don't have such a high dynamic range. -- Alfred Molon ------------------------------ Olympus 50X0, 7070, 8080, E300, E330 and E500 forum at http://groups.yahoo.com/group/MyOlympus/ Olympus E330 resource - http://myolympus.org/E330/ |

Check the Canon 5D or if you really want to go there the MF backs like Phase 0ne and such.

See: Procedures for Evaluating Digital Camera Sensor Noise, Dynamic Range, and Full Well Capacities; Canon 1D Mark II Analysis http://www.clarkvision.com/imagedetail/evaluation-1d2 The Nikon D50 is he http://www.clarkvision.com/imagedeta...tion-nikon-d50 To get high dynamic range, you need large pixels, which P&S cameras generally do not have (typically 3 to 6 times less photons than DSLRs). See tables 1, 2 and 3 at: http://www.clarkvision.com/imagedeta...ignal.to.noise for some data on other cameras. Unfortunately, there is not yet much data on P&S cameras compared to DSLRs. Roger |

You can always take multiple exposures and layer mask them if you want the best quality. Actually you do better to use HDR for multiple exposures. HDR is not for everyone, as layer masks give much more control. Also, it's quite possible to get a nice bump in latitude by layering a few different developments from one RAW file. -- John McWilliams ps JS- you sig delimiter has gone missing. |

I've tried it both ways and I find layer masking works better for some kinds of shots, HDR for others, depends on the type of shot and the end result you want. For a simple sky/land split I find that layer masking works better, and quicker. I prefer HDR for shots that have a more complex mix of shadows and highlights, like sun-dappled foliage for example, or indoor shots with bright lights. Paul |
