really i wish i would find some time and finish (or actually start) a python based front-end for the command utility exiv2. but unfortunately until now, there is just a bad first version which i have used so far …
film cameras doesn’t store metadata onto negatives (maybe there are some … ?). taking pictures is fun and processing them in darktable gives them the little extra. so i like to scan all my negatives in tiff format for post processing. but the tiff files than do not contain any metadata about camera, lens, settings, timestamps and so on – i like to have those data already in the tiff files! under linux there are several opportunities to store exif data into image files and the command line tool exiv2 is one. but applied to each image file dedicated exif data is not fun, doing it by hand and one-by-one. a kind of automatisation is needed to save me a lot lot time.
the python gui already helped a lot but till now it has a lot of drawbacks and bugs – starting slow and each image needs to be accessed alone – … doesn’t saved me time well! something else was need until an improved version is done.
what do i need is a quick solution to store certain exif data to a couple of image files in a bunch. i shot a film so mostly i need have about 36 images with the camera and lens data. for the moment i do not note camera settings or dates, when and how it was shooting. but i like to save a date and time with an increasing second on each photo to have the order of the shots. in addition i like to fall back on a kind of database where i have different cameras or lens data to be stored and not to think and type in again and again the information i need to have.
starting to write a bash script seamed to me the quickest solution and i already had done some other simple little gui helpers with yad dialogues. at the end i’m actually quite happy with the script i wrote. it contains now each function i liked to have. it even stores different camera and lens data. all the equipment i’m currently using. the usability of the script, i think, is also quite nice. as it is stored as a nautilus script in my system, i just need to select the image files that should obtain metadata and invoke the script from the nautilus menu. the gui opens and data can be selected or changed and entered which should end up in the files. the script is ready to use and contains in it data about camera and lenses – extensible for additional cameras and lenses.
work done – now i’m out and shooting! 8)
… and the script i’d like to share
