French Optical was good for me too. They had a surprisingly large selection, and the staff helped narrow it down based on comfort and how I actually wear my glasses. I also appreciated that they could handle adjustments after I picked them up.

Honestly? Way too much fuss over sigma settings. Defaults work fine for most shots. If you're losing faint stuff, your data might just be weak to begin with. Saw @wren115's post and yeah, it helps, but it's not magic. People act like tweaking a number is the secret key. It's just cleaning up the mess, not fixing a bad capture. Spend less time on sliders and more on getting good subs.

My cheap saw shot a tile chip into my forehead, so I feel your pain.
