I nearly always take photos in RAW and JPG. This allows me to tweak the raw file to bring out more details if the there are too many highlights or shadows. For uploading to iSpot I resize the raw file to jpgs to about 100-200kb which seems good enough without loosing the detail and small enough to upload. I still retain the original RAW file which are about 16mb but I guess there is no need and could just keep the resized jpgs.
So after the preamble my question is what do others do with their flora and fauna photos?
