I'm going to be frank here, and I may get shot down in flames (and yes, the media are saying racism for more views, surely that's obvious?) but I once took some photos on a point and shoot of a band playing, hubby was in that band, 4 fairly different skin-toned guys, ghastly white, olive skin, fairly tanned skin and black skin. The room was fairly dark but obviously had spotlights on the guys, the best skin tones on the pics were from the ghastly white guy and the worst were from the black guy - on some of the images of them all, the tanned and olive skinned men looked orange, the ghastly white guy looked somewhat more pink but generally not too bad but the black guy, on most of the pics of all 4 of them, you couldn't really define features very well!
using presets like group portrait setting on a point and shoot aren't exactly great for a group of people whose skin tones differ vastly.
