I was referring to watching/modifying Raw images on your Ipad.   So far, you
would be watching the embedded jpg.  Not the ( hi resolution) raw image.

IOW, the Ipad is useless for careful and precise work on image
display/manipulation for enthusiasts using anything but Jpg images.

I might add that I think it would be a brilliant tool for hi res portable
image display, if only they would allow for us 1%.

Frank, possibly you are referring to the low quality preview thumbnail
embedded within the DNG?
The image program in your tablet/Mac/PC still needs to understand the raw
data and format to be able to show that.
You can optionally set the M9 to save the image as a JPEG instead of DNG or
as well as a DNG. Those will still be at the full resolution of the sensor
but of variable quality. That is what Gene suggested in an earlier post I
think.
 When you import your DNG files with your Raw Converter (such as Lightroom)
you see those thumbnail previews initially but LR can optionally make new
medium or full quality previews for you. With editing, those will get
updated in the background at some point.

You might know too that DNG is a true raw format but in any case, Lightroom
or Adobe Camera Raw does not alter any original image including a JPEG when
you edit it. The edit instructions are  only recorded. So you can actually
make or unmake edits to JPEG files in those programs with no penalty and no
resaving which is where you can lose further information.
You can choose to save a new version of the file which does have the edits
applied of course.

Cheers,
Geoff
