Today’s Question: Can I change which metadata appears when I enable the overlay in the loupe view in Lightroom Classic by pressing the letter “I” on the keyboard?
Tim’s Quick Answer: Yes, you can modify the settings for the info overlay in Lightroom Classic on the Loupe View tab of the Library View Options dialog.
More Detail: Pressing the letter “I” on the keyboard when in the loupe view in the Library module in Lightroom Classic will cycle you through three information overlay displays. The first time you press “I” it will show Loupe Info 1, the second time it will show Loupe Info 2, and the third time the info overlay will disappear.
You can configure the specific information that will appear on the three available lines for each info overlay configuration in the Loupe Info Options dialog. To get started choose View > View Options from the menu. In the Library View Options dialog select the Loupe View tab. Then choose the desired metadata field options from the three popups in both the Loupe Info 1 and Loupe Info 2 sections.
For example, you might want to have camera and lens information for one of the info overlays, and exposure and capture time for the second info overlay, perhaps with the filename at the top of both options. Note that the top line of the info overlay text is larger than the other two lines, so you might want to put whatever you consider the most important metadata field on the top line. When you’re finished setting the options, close the Library View Options dialog.
Once you’ve configured the desired metadata for the two info overlay options, you can use the letter “I” keyboard shortcut to cycle through with an updated display based on your selected settings.
