Why is the date and time correct in iPhoto, but incorrect in Lyve?

Is the date and time on specific photos in Lyve different than what displays within your iPhoto library? You might have some photos in your library that are in the .BMP (or bitmap) file type. It’s not the most common file type for photos, but it has a widespread familiarity in Windows operating systems and elsewhere. So, you might run across BMP files here and there.

The most important thing to note when managing your BMP files is that (unlike JPEG files, for instance), they do not support embedded EXIF metadata. What this means is that, although you can change the date and time of BMP files in photo management tools like iPhoto, and they show up as having the correct date WITHIN that application, it still won’t pass the correct date to other apps like Lyve.

When Lyve begins to read and sync your photo library, if it encounters BMP files, the only date & time stamps it can grab are the file creation dates associated with that file, which may be wrong.

How do I know if they are bitmap (.BMP) files?

In iPhoto, select the photo in question, then choose Info from the View menu. iPhoto will display the file type information for the selected photo.

How do I fix this?

So, if iPhoto or similar tools can’t change the date metadata on your BMP files, how do you do it?

One of the best ways to handle this would be to convert any BMP files to TIFF or JPEG. TIFF files support lossless compression, and JPEG files (while not lossless) are extremely compact. Both TIFF and JPEG files support embedded EXIF metadata and pass that metadata to Lyve.

  1. To convert your BMP files, you can use a variety of photo editing tools. In iPhoto, for example, it’s very easy to do:
  2. Launch iPhoto, then locate and select the BMP files you wish to convert.
  3. Go to the File menu and choose Export.
  4. Within the Export window, choose TIFF or JPEG as the Kind, make any other changes you’d like to make, then click Export (place the exports somewhere easy to find, like your desktop):

  5. To prevent duplication, within iPhoto, delete the BMP versions of the photos you just exported. You may wish to double-check that your photos were all exported properly as TIFF or JPEGs before you empty the iPhoto trash. See this article for more information on handling duplicates: How do I remove photos I don't want in Lyve?

Re-import those TIFF or JPEG files into iPhoto and change the date and time (see this article for more information on how to do that).

Lyve will automatically import those TIFF or JPEG files with the corrected date and time. You're done!
