I used to download “True Colour Imageries” (TCI) through the S3 bucket. It’s simple and easy, via a web browser too.
All it takes is go over here, for example; focus on an area of interest. To download a particular scene, a URL to the S3 bucket will be provided. Bob’s your uncle!
Since I don’t have an always-on (and unlimited) connection, one single file (TCI only) is ~150MB tops. That shall be sufficient for a quick and rough edit.
Recently I’ve learned that the access to the L1C S3 bucket is put behind a paywall. Sad news, for me, indeed.
The only alternative left is downloading through the Copernicus Open Access Hub (free signups). However, this means that I will need to download the whole scene (various spectrums) in a compressed archive: ~700MB zipped file. Which is (uh, ahem) a little bit excessive on my side. Well, well.
