DNG image looks sharper than TIF of the same image in Lightroom although they look the same at 1:1. The DNG has more contrast & sharpness & the TIF, PSD, JPG look flat & blurry even with !:1 preview being generated. I tried exporting the edited TIF to a DNG, but the new DNG looks like the TIF. If I export the DNG as a DNG the new DNG is the same as the original. I don't believe the older version of Lightroom did this. It is disturbing & frustrating because I think the TIF needs more editing! Yes, I can check small portions of the TIF at 1:1, but that is inconvenient & time consuming. In Bridge it's the same except even the DNG isn't as sharp as Lr unless I open it in CR.
