In testing a 6 megapixel 2816x2112 image just now with a lot of detail in
it
(foliage and animal fur), the original 3meg file compresses down 416k at
RealOptimizer's 50% setting with virtually no image degradation nor
downsizing
needed.

Thee only problem with this is that jpg artefacts are usually first noticed
as blocking in large areas of slightly varying tone like the sky. Were
there any areas like that in your test photo?
