Hi, I don't know much of anything about microfilm. I'm guessing the answer to the question in the subject is no but wanted to find out more about it. I am not speaking of originals that have been modified and then microfilmed (that has been ruled out in this case) but rather the modification of the finished microfilm itself. This would also include not obvious ways of inserting a new, modified picture onto an existing roll of microfilm that is derived from the unmodified microfilm picture that was removed from the reel (if any of those sort of ways even exist).
Why do I ask this? Because I have a piece of microfilm from a piece of newspaper from the 90's that looks a little odd. My gut tells me that a certain portion of the picture looks inconsistent. I will not say what part I think might be inconsistent so that you can have an unbiased look at it.
Here is the image in question (scanned with a microfilm scanner):
What do you think? Do I just not know much about newspaper/microfilm and have higher standards for consistency than those formats are able to provide? Sorry if this notion of modified microfilm seems silly but I really have no clue. I'm a digital guy. Microfilm is before my time :)
