Odd thing - the image uploaded to Flickr isn't nearly as sharp as the one in LR.
Trying a direct upload instead.
- Edit: image here also seems to lack applied sharpening, and is a bit softer than my local copy. Hmmm
I also often find a regrettable loss of sharpness when I upload an image, presumably from the downsizing algorithms that we use to make the image fit the constraints. Some images altogether lose their impact. An image that depends on microcontrast and small details in juxtaposition and contrast to each other especially suffers. Sometimes it really looks like half of the image is missing, which is in fact literally the case (or more than half actually).
There may be ways of processing an image for downsizing and uploading that makes this less of a loss and less of a problem, but I haven't discovered it yet.
