Add meta information to photos? Is there a decent camera app that will easily let me add a bit of text to my photos and store that text in the image file as EXIF/IPTC/XMP metadata? So far I have tried the stock Samsung camera app, Camera Zoom FX, Camera FV-5 and Catch Notes. I have read descriptions on numerous camera apps, but it seems like all they have to offer are various ways to distort - I mean enhance - your photos. While Catch Notes did offer ways to store your photos along with a description, it did not store the info as meta data inside the photo itself, which means it will be a mess if you ever want to transfer the photos to your computer and expect the data to stay intact.

This seems like a no-brainer that you'd expect to be available in almost every camera app. I mean, we've got the camera and the keyboard in the same device - what's the problem? I just want to be able to take a photo, click on an icon and type "This is a Bohemian Waxwing" and have that description stored inside the JPEG file. I'd even be fine with a gallery app that only let's me add information to already existing photos.
There are a couple of apps in the Playstore which permit you to view/Edit EXIF data:


Photo Image Editor - Photoshop (free) says it can View, edit, or delete EXIF data
Same promised by Photo Editor
Exif Editor and Viewer (paid) promises to remove, modify, and add individual or multiple EXIF tags
Pixelgarde even states: Edit exif metadata for several photos as a batch, or just individual photos


There are probably many more, so I just picked two of the more promising examples.
