I've noticed more often than not, when people import their images into Lightroom, that they try and decide what to keep and what to toss all at once. In other words, they will import their files and then starting from image #1 they move down the line "keep it",,,, "toss it"…. and at the same time they may also attempt to rank it, decide their favorites and decide what to show on their website or portfolio – All this in a single viewing. I'd like to present my method for sorting my imports and explain why the process needs structure and objectivity.
In the end you'll find it's easier, faster and gives better results.
