I've got my hacksaw out and am busy trying to get my Paterson developing tank attached to my Canon T90. It's going to be awesome - imagine being able to take pictures, then develop them on the spot and see them immediately! Ok, so the enlarger mounted on the other side of the camera is going to make it slightly unbalanced but the benefits are going to make it worth it. But seriously, why waste the time? I take mainly landscapes and have found the best way of working, and one that gets gasps of admiration from those that see my photos, is to take as many snaps as I want and then go to the computer and download pictures of the same place from Flickr. My photographs have improved out of all recognition since I adopted that work-flow. Or, to put it another way, no - I have the option to post-process in my GX-10 but have never been remotely interested in exploring what it can do.
