Even that is 1NF, probably. As long as you don't have the id,blob duplicated in a table. 1NF (depending on the definition) has a few subtleties that make it either impossible to avoid in any relational database or almost impossible to enforce! By impossible to avoid, I mean the basic rectangular shape of a table. By impossible to enforce, I mean the avoidance of duplicates (without indexes) and NULLs.
