Ah the beauty of youth…
Looks a tad underexposed to me…
I was for a while but these were jpeg.
Is your EVF set to a manual brightness, or to auto brightness? It's adjustable. Note too that one of the display options (I hope is to include an exposure histogram overlaid on the image. For quick snaps with my Sony A77 I'll use the EVF to judge exposure compensation. Mostly I don't need all the dynamic range of the almost ISOless sensor, so there's free latitude in post processing adjustment if I misjudge. But if I'm spending any time on posing and lighting I'll also be checking exposure via the histogram to be sure it's optimised.No argument. Something I have yet to get used to with my Sony a6000 is that images look brighter in the viewfinder than they come out when exposed. I am struggling with this as I must learn to estimate compensation.
