Thank you! It was one of those autofilters from Google Photos. I tweaked it a bit and copy-pasted the edits to all the other photos. The filter was necessary, rather than by design - the lighting was all wrong in the original photos and my daugher's blue hair (an experiment gone somewhat wrong) clashed with everything else in the house
I just love this, Olga! It looks like the ordinary moments of life, which i love so much. The black and white photos are what makes this page so special!!
