The Limbo Connection's photos with the keyword: cleaning lenses

A completely accidental photograph which occurred during the course of preparation for cleaning the sensor of a Fuji S3 Pro. I uploaded it simply because I liked the geometry, texture, and reflections. The sensor clean was almost a success. There's still a blob of crud over on the right-hand side, where the sweep of the swab terminates. You can't see it in this photograph, nor a good many others. I'll tolerate it for a while. If you can get a photograph like this by shooting through a window pane - and I haven't given it any software assistance, this is SOOC - what does it tell you about dirty lenses, etc? I doubt you need to be over-fastidious.
