Address JPEG vs TIFF for raw file formats? #143

Open ewallace opened 9 months ago

The file formats part of data management episode is focused on .csv files and other text-based formats.

It might be helpful to say something about images and .JPEG vs .TIFF, and link to the blogpost from ASBMB/Kaoru Sakabe, combating compression https://www.asbmb.org/asbmb-today/science/050117/combating-compression

Good point - is the key point to make sure to save and publish your data in lossless open formats? There can be a tradeoff there in file size and efficiency though as tiffs are much larger than basic jpegs. JPEG 2000 is a lossless file format that could stand in as a reasonable choice that's more efficient than tiffs for rendering / processing / storage, and PNG files are also lossless.
