First off, I take everything he says with 2 grains of salt. But I was reading Ken Rockwell X100 set-up preferences and he claims that there's no difference between the NORMAL and FINE JPEGs other than wasting 50% more card space. Is that really true? Before I go the trouble to shoot comparison shots and pixel peep, can anyone confirm this? And if true, would the fine JPEGs still be less likely to breakdown during PP since there is theoretically more info there?
