I nearly always scroll lemmy on my phone, so when I can't find the Waldo right away, I zoom in and start panning around. But with this find Waldo picture, I can actually spot the leopard easier when not zoomed in. It just pops out for me, my cat has probably trained me too well.

I think the issue with the boredpanda picture is that the original photo was already fuzzy (long distance shot I think) and a compressed jpeg. Someone at boredpanda then cut out a too small part of that and jpeg compressed it a 2nd time, giving the leopard additional dazzle camouflage on top of it's natural camouflage.
