I assume you are talking about your experiences opening the image in 
the SVG viewer 
(http://www.openmicroscopy.org/getting-started/svgViewImages.html ).

The images are not "processed" during import. Its a raw import. We do 
compute several global statistics about the pixel intensities (e.g. 
min, max, mean, variance).

The image "seems too dark" because the SVG viewer display settings 
(move the sliders on the GrayScale Map/Color Map bars) are different 
than you expected. Change them to suit your needs.

Yes you can zoom in and out. Hold control when clicking on the image.

Regarding panning. Its not possible, and scrolling doesn't work that 
well.

Regarding TIFF metadata. Which meta data did you expect to be imported? 
We import meta-data that's in our OME XML Microscopy Schema. Obviously 
that's metadata relevant for microscopy not digital photography.

As you observed, OME is not designed for those types of images. If you 
want some images to try to import look at 
http://www.openmicroscopy.org.uk/TestImages/ . You have over a 1GB. We 
trust that will be satisfactory for a taste.

Enjoy,

Tom
