I have created a smart collection in Lightroom 5 for images (RAW) not previously edited or adjusted. My intention is to work with these images in the develop module, but as soon as I change any variable in the D module for a particular image, that photo disappears from view. This kind of makes sense, since it will then have been edited and, hence, no longer belongs to the smart collection according to the ruleset I've defined. A workaround would be to first finding the photo in its original folder before developing it, but that seems to defeat the whole purpose of using collections.
My question is: how do I define my smart collection in LR5 for unedited photos so as to be able to select an image and then develop it without it immediately leaving the collection?
