Thanks for testing this and sharing this. I was most surprised by the resizing by 1 pixel image.

It would also be interesting to see how the degradation evolved with the “save as…” and “resize” options. These were clearly the processes which generated the worst images, and if you had one picture which was “saved as” 10 times, one “saved as” 20 times, one “saved as” 30 times, etc. we could se if there was a critical point where an abrupt degradation ocurred or if the process degraded the picture linearly with only small changes from 10-fold to 10-fold “save as…” actions.

Wow - those are some scary results! I’m glad I shoot in RAW and use LR and PS to avoid this kind of thing. Having said that would I really open and save a jpeg 100 times?
