Where's the smiley face? I assume TIC?

In case not . . .

The camera demosaics the Bayer array. One knows because the TIFF is three times the size of the sensor, 8 MP for each color. (ORF/Raw is 13.6 MB)

There is, of course, no more detail information than in the Raw file. (Some of Topaz' recent AI based app/plug-ins do, in fact, invent plausible details, but the E-500 doesn't.)

The impression that the TIFFs are particularly sharp may be because the 1.8 MP JPEGs he refers to are heavily compressed using JPEG's lossy algorithm. The manual says a 1.8 MB JPEG is highest level of compression the camera offers. You can't compress to 1/12 size without losing a lot.

Could also be some sharpening applied to the TIFF.
