In the process of editing my #btconf images from earlier this week:
I did take 1,641 images in total. 805 were left after the first pass, 406 after the second. Now down to 219 photos. I usually aim for something in the range of 150 or so images. Getting rid of the last 50, is always the hardest part.
Final thing after that will be sequencing. I mostly go with chronological here, but sometimes, moving a couple of images around makes for a more interesting flow.
Stay tuned!
