Isn't that a bit extreme?
To accommodate for many photo's with other aspect ratio's (especially portrait of course), this is not an improvement.
16:9 = 1,777
4:3 = 1,333
Perhaps making it 3:2 (1,5) would be a better compromise?
And to be totally honest, 4:3 was fine by me already as a compromise.
Well, I'm agree with Bee-liever
The 16:9 format dominates know, and for those images that don't fit, I'd much rather see some coloured stripes that blend to the panel background colours, than have the sometimes strangely cropped images we get now.
imho, 16:9 is the best compromise because, sadly, as Bee-liever said, 16:9 aspect ratio dominate now.
16:9 -> most of your pictures fill perfectly the frame. Few of them are cropped or displayed with strips
4:3 -> Almost all your pictures are cropped (or have strips).
It's exactly the same thing for Album Artworks. I have many CDM, Deluxe/Collector's Edition, Box-Set... Most of them don't have the 1:1 aspect ratio (many are not even rectangular). But I still prefer the 1:1 aspect ratio because most of my collection uses this ratio.
But I can understand your point of view. I'm working at the moment on a new layout/skin and it's all about portait orientation artist pictures ! (but I still think 16:9 should be the default setting):
