How to correct exposure locally with Apple Aperture? I've awarded it because I had asked this almost a month ago and the awarded one was the first that came close to answering my question after 3 weeks. I did not expect to get any better answers by then any more. It's a bit surprising that now several better solutions come up, 4 weeks later :) |

How to correct exposure locally with Apple Aperture? Thanks for trying and confirming my findings with Aperture. And also thanks for clarifying that it should be working better with Lightroom. |

How to correct exposure locally with Apple Aperture? Sorry, but your answer is a very generic one that doesn't apply to my problem. I've tried the "darken" brush first but it didn't do anything closely to what I get with exposure set to -2. It's rather useless in this case. You may verify that yourself - I've made the original file available (though, when downloaded, it gets a .tiff extension though it's really .pef!) |

How to globally fix missing files in Adobe Lightroom? Sure, if I make such a tool, I'll let everyone know, you can bet on that :) |

How to globally fix missing files in Adobe Lightroom? If you like to work this out with me, email me directly and I'll see if I can spend a few hours on a quick app for this tomorrow. |

How to globally fix missing files in Adobe Lightroom? Okay, there's one possibility to solve this with a program, it seems: The database file that contains the references to the original files is a standard sqlite DB. In that, I can find the file and folder references. It remains to be seen if changing them would work without upsetting LR. This could be an opportunity for a tool. I just wonder how many would buy it, i.e. if the effort would justify it, from a viewpoint of a software developer. |

How to globally fix missing files in Adobe Lightroom? Alright, but "how can I reorganize my pictures into different folder structures with LR keeping their refs" is a totally different question. |

How to globally fix missing files in Adobe Lightroom? I just checked LR's Applescript capabilities. Sadly, it doesn't provide any access to its photos database, so that's not an option. |

How to globally fix missing files in Adobe Lightroom? I once wrote a similar tool for iTunes. I used iTunes' Applescript capabilities for that. I wonder if the same could work for Lightroom. Not a solution for your immediate needs, though, thus only a comment. |

Stitch first and edit later or vice versa? @MattGrum - I had tried a few stitching apps and they failed at the gradual decrease of brightness in my 360 pano sequence - all they did was to "smooth" the first and last picture by adjusting the area where they overlapped, which was not creating a good result at all. I don't know of any app that would understand that it has to change the brightness gradually of ALL involved pictures in the panorama, unless there's a way one can direct them manually to do that, but surely not automatically. |

What's the difference between vertical and horizontal shutters? Having disassembled lots of SLRs in my youth, I can confirm this. Horizontal shutters were using cloth as a curtain, which got rolled up when cocking the entire shutter mechanism. Later SLRs then had the vertical shutters without curtain but with blades. These required more complicated mechanics. |

If I transfer files from a CF card to an iPad2, will I lose metadata? I have just tested this myself: I take a RAW+ img, put the memory card into the iPad via the adapter, import the imgs, and finally import the imgs from the iPad to the Mac. Turns out that the files (JPG + PEF in my case) are identical in size to the original ones on the card from the camera. If that's not what you experience, please give more details, because so far I can't confirm what you're seeing. |

Equalize exposure levels of a set of images in a stitched panorama Thanks, Mike. Your various explanations on how to apply the gradiant were helpful as I'm still learning these tools. On the question of aligning the exposure of the tiles - I'm now planning to write my own tool for this, and maybe publish it later, as I believe this could be useful to others as well. |

Equalize exposure levels of a set of images in a stitched panorama @Itai But my particular explanations are besides my point to you: Your claim never to use a flash is quite inconsiderate, as you rule out that people may have special cases where the flash is the better option, like in my case. If you want to be a good teacher, I suggest you don't deal in such absolute and final statements. |

Equalize exposure levels of a set of images in a stitched panorama @Itai In my case I actually had the flash on camera because I didn't have the full eqipment with me and had to do with what I got . The artwork was being disassembled soon after, so I had no choice. And it was a rather strong flash. I had also tried without the flash first but exposure times ran into seconds, and the contrast was rather low. In the end, with the flash I fared better. |

Equalize exposure levels of a set of images in a stitched panorama @itai I disagree. A fixed positioned external flash that's not moving with the camera, or even two of them, shouldn't be a problem. Besides, I've had a rather long distance from the object, and the stitching software had no problem whatsoever. |

What does the under/overexposure warning mean in image editing software? Yours and the answer from Miguel still do not really make me understand the effect. I am a software developer, so I very well understand the file format and meaning of number ranges. And because of this background of mine, I have trouble accepting these limitations I've described in my question. |

Do smaller apertures provide more depth of field past the diffraction limit, even if peak sharpness suffers? @Jerry: Impressive demonstration, showing the effects of diffraction so clearly. I had no idea of this effect until I stumbled over this question rather accidentally. (Though, as a hobby astronomer, I know this effect for very long, I never made a connection to photography.) |
