Clouseau should tell us what version of Vue he uses. If Infinite, Clouseau should choose to use the Hybrid 2.5 blur effect with 4 passes. Noise free, but not 100% accurate.
IF Clouseau uses any other Vue version, he should increase the anti aliasing settings. A lot.
As to upload an image, Clouseau should use the gallery button in the header of the site, and then the upload button. And get glasses. Clouseau is not that young anymore.
