I have heard it said that the creative filter applications available for phone photography are simply a way to make bad photos look good.
I would have to say that these filters are a way to make bad photos look worse.
The web is filled with horrible photos of pets, selfies, and dinner plates, often processed through some creative filter application to somehow make the photo look hip or cool. Sorry, a bad photo is still a bad photo. Often it is far worse for the application of the filter. Fancy colors, brush patterns or mosiacs, it does not matter, it is still just bad.
I am not telling you to uninstall the application, quite the opposite! A well composed photo can be a good photo after application of the filter. You can also use the filter to overcome some limitations of phone photography. Technical defects like color, lighting, and noise are often erased when the filter is applied.
