Here is my option...
in my prediction C is sony,B is Nokia, A is Samsung and D is LG..come on tell us the identity of the phone :p
Cool idea GSMARENA!!!!!
I go all the way with C.
Cameraphone B & Cameraphone C have slightly same performance. Two of them is the best among the 4 cameraphones. My favourite among the 4 is cameraphone C. In my own eyes, I believe it produced the best pictures among all the competitors. Juz my 5 cents^^
i'l have to rate them as following: C, A, B and D the same spot(read : bad pictures), i sure hope the best is the Lg cause i'm a big fan of the new cool features it has, but also SE is a great phone.
It would be great to also supply a shot of each scene using a proper camera so that we know what the scene is supposed to look like when reproduced faithfully. The flower shot, for instance, varies a lot from phone to phone, and it's hard to tell whose color is the most accurate.
I loved the contrast, colours and detail in C. A is also very good but the level of detail is not quite as good. There's a reddish tinge to the shots from B but probably just beats D because of the level of detail.
For the close-up shots, the reddish tinge to B is quite apparent with the red flower though it has focused on the violet flower beautifully. I'd mark A down a little on these because they're just not as well focused as the others.
So to summarise, if I was to choose which set of shots I'd be most happy with, I'd go with C, A, B, D.
Judging by the pictures, A=Nokia, B=SE, and C & D are Samsung and LG. (the macro pics reveal the SE :P )
D is way to pale, the colors are washed-up, so it is the last place.
A has good pics if you look at them from a distance but the fine details are gone (look at the third set of photos, at the stone in front of the train - observe the pattern on it - if there is one...)
B and C have the most natural colors (my opinion, don't shoot!); B has the best macro, C the best details reproduction.
Conclusion: ... I don't know; B or C ??? (SE or Samsung) ...
P.S.: I own a SE K850.
