Fix very slow iPhoto load and/or quit time
Stripping out all EXIF data isn't necessarily a good idea. This contains other info, such as when the shot was taken, what the resolution is, white balance settings, whether the flash was used or not. On more expensive cameras it will also record camera-specific stuff such as what the apeture setting is, speed rating etc. I think with iPhoto 5, the EXIF data is also used to record which position you've rotated the photo, so you might find stripping out all EXIF data may result in your photos returning to their original orientation. It's also used to store information by some tools (though I think iPhoto uses the metadata resource fork) such as who took it, any comments added and so forth. You should generally avoid these types of cameras that generate large amount of extra data rather than stripping them all; in particular, you should avoid Nikon cameras. They encrypt the white balance information (essential if you want to do much post-processing on your computer systems) to prevent 'unauthorised' use of the information. They've also been threatening to use the DCMA to prevent people using anything other than their tools -- which unsurprisingly don't run on Macs.
fix iphoto and avoid Nikon? I think not...
I agree that stripping the exif data isn't necessarily a good idea, although most iPhoto users likely won't miss most of this info. If I'm not mistaken JPEGs have a header with this info anyway (for use by the software). |
