<p>Photomechanic is the fastest solution to culling images. I average around 45-60 minutes to cull 4500 images. Culling in LR is not ideal as you firstly have to import all the pictures and it's slower.</p>
<p>Also, edit "in"and not "out". In other words, mark/tag the keepers, not the rejects. This is more efficient.</p>
