Is it possible to read EXIF data with R?

Question

I need to manipulate some image files based on their EXIF data. Can something like this be done in R? I have not seen any R functions which could read EXIF data directly.

Answer 1

The adimpro package may be useful. It maintains the EXIF data as a comment() on the imported image. (not used it myself though.)

Answer 2

I could not find an R package that did it natively either, so I implemented my own at https://github.com/cmartin/EXIFr

As of now, it only reads a subset of tags I was using for a project, but I could easily extend it to suit your needs.

For example, to read the aperture value :

read_exif_tags(image_path)[["ApertureValue"]]
