This is something I've been curious for a while.
Do you guys ever use the crop tool, without a specific ratio (cropping freely ignoring ratios.)
I for one, don't. I always am either cropping 2:3, 1:1, 4:5, 5:7. Maybe on the rare occasion I'll try 16:9. The only time I think I would not use any of these ratios and maybe crop freely is a panorama, but even then I think I'd find a super wide ratio I like. I crop with these ratios to whatever I think is the best fit / crops tightest to what I want.
