[Galaxy S 4 General] Terminator19:
It is pretty obvious and well known that if you want to crop/zoom in on photos, then the one is not the camera phone for you, it simply doesn't have enough megapixels.

Viewing the one photos on my calibrated dell U2331H monitor look very good (when not zooming in), especially macro shots (macro shots look better than what my one S produces and it is has a superb camera), now if I had a very high res. panel then my opinion would be different.

Getting tired of people saying this xxxxx phone is better than this xxxx phone, this xxxx phone sucks zOMG!!! As if to say that only one-two area matters, there is more to a camera/photo quality than just the ability to zoom and good or/and low light conditions....

This is how I look at it:

Main advantages of the GS 4 camera over the one are;

- if you crop/zoom in on images, have a very high res. display and/or print photos on large paper, this is where more MP really shines!

- Bright landscape conditions

- panorama shots

- features/options overall

Main advantages of the one camera over the GS 4 are:

- very fast shutter and combined with OIS, you get more consistent/usable photos, more so in lower light conditions and/or with movement shots

- indoor conditions, low light/dark conditions

- much larger FOV

- audio recording (really amazing in loud environments) and video recording overall (GS 4 looks excellent for 1080P recording but the OIS, FOV [which is further reduced on the GS 4 when you enable image stabilisation] etc. give the one the edge by quite a bit imo)

The GS 4 can perform superbly in low light/night conditions with "night" mode but it comes at a cost, slower shutter thus only useful with non moving objects and you need to have a steady hand.

Regarding the features/options, both seem to be more or less the same, GS 4 has the edge with a few more things to choose from. Most of the one's features are tied to the zoe feature and gallery i.e. sequence/drama shot, always smiling, eraser/removing objects etc. where as the features on the GS 4 are selectable through the camera app.

Macro shots look superb on both, need to see more from the GS 4 end users, but so far I think the one is better in this area, the photos are just very detailed and have a "natural" look to them.

Up to the end user this part, but photo size is quite different due to the difference in MP, talking about 1.5MP on average for the one VS 6.5MB for a photo from the GS 4, personally for me, smaller photo size is a nice wee bonus.

Haven't seen many HDR shots from either phone except for some of the review sites, but both look very good in their own ways.

And I haven't even covered the actual "quality" of the image i.e. in terms of colours etc. From what we have seen so far, I would have to say that the one looks more natural and the GS 4 saturates the photos a wee bit [which I quite like depending on the scenario] (saying that, this is easily solved by adjusting the contrast or saturation in the one camera app, can't remember if you can do this with the GS 4 camera app???), however, in some shots i.e. white/grey buildings, the one looks too yellow, the one had a problem with exposure i.e. white clouds, very bright conditions etc. but this has been fixed/improved with 1.29.

Both phones will improve with updates, especially the HTC one since the camera tec. is fairly new for a phone camera especially to HTC (only two phones have OIS, the other one being the lumia 920)

Comes down to what the end user wants.
