i can frame a shot @ 16mm, single portrait framing...
look at the sides of the photo, how tight it is... and notice the amount of dead space in the sky which does not add much to the photo.. imagine the sun is setting right at the horizon already, then there will be too much sky and the photo will feel top heavy...
and this is on slightly lower floor, i need to go up higher to get the leading lines working.. going higher will mean capturing more of the sky...
so i work on landscape framing with 2 or 3 images stitched vertically aka vertorama...
though of cos, this photo involved exposure blending too but that's not the issue here... end state i felt was a much balanced output with 1/3 sky and 2/3 foreground.. top of HDB flats leading to the horizon where the drama is... the left and right sides had some breathing space, not so squeezy like in portrait framing... a squarish crop worked pretty well here..
yes yes, YMMV as always...
