At least a few trips out to see whales a season. I can't live without them. And each encounter, I learn more of their behavior, more of their personalities...!
I, too, love heading back thru Lightroom, and opening up old albums or old images, not only to relive, but also, to reprocess. During the pandemic, when I went out maybe less than a 1/4 of the photo trips, reliving the old Catalogs, and Albums, saved my sanity!
My technique when I first started w/ Photoshop and Lightroom was "heavy-handed" to say the least. Going back to the original raw, and reprocessing, now, feels like a whole new adventure.
