Didn't quite get that last remark. A drum will take up just a tiny amt of the space required by trays.
That's the whole point. Plus way less volume in chemistry. And not necessarily difficult to load and
unload at all. Whether or not they process as evenly as trays is a function of how well they are
As far as I know, drums are the only way to soup prints in spaces other than a darkroom, that is my primary reason for using them, not only do they take up less space when doing large sizes, you can use a kitchen or other bright area to get the job done.
