Does the JPEG Quality Matter?

Quality set to 0. The resulting file is only 4.4 kB.

Quality set to 10%. Slightly larger than its neighbor (4.5kB), but looks just as bad.

Quality set to 25%. Still sucks, particularly the wall behind the plant. File length: 5.3kB.

Quality set to 50%. Now we are getting somewhere, except the wall still looks a bit grungy. Low lighting (fixed in post-processing) is partially to blame. The size doubled to 10.7kB.

Quality set to 75%. We're getting somewhere now, but he size doubled again, to 21.9kB.

Losless - 100%. Yes, so its quite a bit better, but it takes 36.6.kB.
