That would be true if we were judging jpeg results vs. RAW results. What Cotty disputed was Adobe's assertion that the RAW converter provides better upsizing than does PhotoShop interpolation. Evaluation of an interpolation is probably best done on the screen. I don't think there's much dispute regarding the difference between jpeg results and RAW results. It's a matter of range and contrast control. It's obvious in some cases and indistinguishable in others. Paul
