Testing the Camera

Another area where Apple’s iPhones are general considered the gold standard is with the camera. Even though Apple’s iPhone 6 Plus camera only has an 8 MP sensor for the rear primary camera, the pixel quality of Apple’s devices tends to be nearly unmatched. The Samsung Galaxy Note 4 has a 16 MP sensor but also includes some impressive additional features like optical image stabilization, LED flash and autofocus as well as 4K video recording.

Samsung has included a lot of options and flexibility in its camera application. You can use the volume buttons for zooming, take photos through voice control (for some reason), apply gridlines on the viewfinder and manually control exposure, ISO and white balance if you want more control

To compare the relevant phones we had at the office we took a set of images with each and have compiled some side-by-side comparison for you below. We took a well-lit indoor scene (our studio set), an outdoor scene from our office complex with a lot of trees and branches for complexity and finished up with a low-light indoor scene with a lot of text to judge sensor performance.

Scene 1 – Studio Set

Compared to the iPhone 6 camera, the Samsung Galaxy Note 4 is able to capture an equally high-quality photo. There is little to no noise on black surface of the studio table and in fact I think the background is a bit sharper on the Note 4. Considering that the Note 4 has double the pixel count of the iPhone 6, it seems reasonable that zooming in on a photo with reasonably good lighting would benefit from the additional data. The Droid Turbo, despite its massive pixel count, actually has the lowest quality result of the three flagship phones tested here. There is noticeable noise and blocking on the top of the black table and the lines in the studio background is slightly more blurred.

Scene 2 – Outdoors

This very complex scene presents a lot of issues for cameras and was by far our largest images in terms of file size. Both the Galaxy Note 4 and the Motorola Droid Turbo full images were 12MB each while the iPhone 6 resulted in only 5MB. Compression is difficult in these cases. The Galaxy Note 4 and the iPhone 6 images differ pretty drastically in terms of color balance with the Note 4 bleeding more into the yellow (and the Droid Turbo even more so). The iPhone 6 image looks best as a whole but again I found that zooming in on the evergreen limbs (where the needle detail can be seen) proved that there is some advantage to having a higher megapixel sensor. The Droid Turbo sees a similar advantage in terms of pixel count as the Note 4 but has more color variance than either other option. Pay attention to the blue in the sky that exists on the iPhone 6 but is washed out in both of our Android phones – that is another instance of the overall quality of the camera rather than a single feature like pixel density.

Scene 3 – Low Light

Ah, the all-important low light test to make sure you can get that shot while you are drunkenly taking photos at the bar. The first thing you notice when comparing the Note 4 and the iPhone 6 is that the Galaxy's images is noticeably brighter. Brighter is not always better, and in my view the iPhone 6 images is slightly sharper on the bigger fonts and slightly less so on the smaller text on the Logitech boxes. Color on the iPhone 6 pictures seem more accurate, but in a void, I don't think anyone would complain about the result the Note 4 produces. And again, even though it has a lot more pixels than either the Galaxy Note 4 or the iPhone 6, the Droid Turbo produces an image that just doesn't stack up.

Scene 4 – Low Light (Zoomed in)

Zoomed in on that same low light photograph, the iPhone 6 still looks a bit better than the Note 4, will less noise on the solid black portions of the Logitech G502 box. The small text "tunable gaming mouse" is more readable on the Galaxy, however.

In a market where the Apple iPhone 6 and iPhone 6 Plus are the measure by which all others are judged, the Galaxy Note 4 stands up very well. I don't believe I could claim that Samsung has built a better camera than what Apple has integrated but I think the competition is closer today thant it has been with previous generation iPhones.
