Sharpen, reduce noise, in-camera, ugh!
Hi,
I have been online looking at the images from some digital cameras and reading reviews. Some of the "better" cameras have relatively soft images - which is explained as being the result of in-camera noise filtering. Some of the cheaper (and / or more compact) camera images look relatively sharper - but that is explained as being the result of in-camera sharpening. This situation discourages me from buying a new digital camera. I would like to have a camera that does minimal filtering but still saves images in some low-loss compressed format. I would like to sharpen and/or reduce noise using image processing programs on my computer - after the fact, as I choose. Any ideas, suggested links to information? Can one turn down or turn off image filtering on any modestly priced compact cameras? I would prefer a compact or sub-compact camera. I am tired of carrying around an old SLR. Thanks, DaveC |

Some compact cameras support RAW formats, which would let you do all of the image processing after downloading to your computer. Off-hand, a few models: Canon S70, Canon G6, Panasonic LX1, a bunch of Fuji cameras, etc. -dms |

Thanks for the suggestions about "raw". I knew about raw, but I always
thought that the raw format is really, really bulky. Maybe with the new 1 gig storage cards this isn't such a problem anymore. Do any cameras let you automatically store in raw, then let you review your images, in the camera, and decide to re-store the less important images in ..jpg? - and delete the raw to save space? I probably would like to preserve the raw version for only 10% of my pictures. Dave C |

Storage is cheap. Some spot-checking indicates that RAW formats run about 1-2 bytes/pixel, depending on manufacturer (highest-quality JPG tends to be 0.5 bytes/pixel or thereabouts). Even in the worst case scenario for file size, you can still fit fiftyish pictures on a 1 gig card. Do any cameras let you automatically store in raw, then let you review your images, in the camera, and decide to re-store the less important images in .jpg? - and delete the raw to save space? I probably would like to preserve the raw version for only 10% of my pictures. There are some cameras that can save RAW + JPG. I would assume that such cameras allow for deleting one or the other, but I don't have any first-hand knowledge of that. -dms |

Since most images benefit from some degree of post processing, sharpening isn't that much of an issue. Dave Cohen |

It is fairly compact, but still takes much more space than .jpg format. You pays your money, and you takes your choice.... |

I probably would like to preserve the raw version for only 10% of my pictures. Yes, but sorry, I don't recall the camera. I read a mini-review recently of one that did allow copies to be made within the camera using one of the alternative jpg formats. You might find it if you check the most recent "news" articles at dpreview.com but I can't guarantee it. [from your previous message] I would like to have a camera that does minimal filtering but still saves images in some low-loss compressed format. I would like to sharpen and/or reduce noise using image processing programs on my computer - after the fact, as I choose. It's not unusual to have a choice of these options in P&S cameras. My Fuji S5100 has menu options allowing you to select sharpness settings among Hard, Normal and Soft, and it (as well as many other P&S cameras) allows for a choice of less or more jpg compression. I very rarely take pictures using RAW, but I suppose it would be very useful in situations having lighting that's unusual, non-uniform or changing. The most convenient place to see whether a particular camera has sharpening options would be dpreview.com's full reviews. If it's not mentioned there, someone in this newsgroup that has the camera might provide that information, or you could download the camera's manual from the manufacturer's website. |
