Dear Maintainer,

=========================================================================================

At the bottom is the metadata reported by jhead on some jpegs.

When viewing image properties with ristretto, the following important
attributes do NOT appear:
- Aperture
- Whitebalance

Eog reports Aperture value under Image Properties -> Metadata and
whitebalance under Image Properties -> Details.

Please consider adding at least Aperture and Whitebalance to the image
properties displayed by ristretto. These are very useful when looking at
a group of test pictures to evaluate lens performance and camera
settings.

Also, both eog and ristretto list "Exposure Program" = "Normal program" but the
result from jhead "program (auto)" is more accurate and maps directly to camera settings.

Another useful image property that should be displayed in ristretto is digital zoom:

Another important attribute that would be useful to diplay in ristretto is any GPS location data present.
Eog displays this location info under Image Properties -> Details.
