With G4, LG wanted to offer a quality camera phone. The Korean manufacturer has focused on the photo part of G4, starting with the 16-megapixel sensor developed internally and coupled to a lens with an f / 1.8 aperture. According to the firm, this new sensor is capable of receiving 80% more light compared to the Sony IMX135 which equipped the LG G3. We therefore wish to compare the LG G4 with two other smartphones whose reputation is well established in the area of the photo on smartphone: Samsung Galaxy S6 and Apple iPhone 6
LG G4. Samsung Galaxy S6 and Apple iPhone 6 camera phones are good. In fairness, it would have also been better to replace the iPhone 6 with its big brother 6 Plus features an optically stabilized sensor. The Galaxy S6 plays big in this game since it currently has the title of best cameraphone being very effective and easy to use. It integrates a Sony IMX240 sensor 16 megapixels optically stabilized (although some are equipped with a Samsung ISOCELL sensor). As for its purpose, it has an aperture of f / 1.9. It’s a bit worse than the LG G4 goes up to f / 1.8. Remember, this number represents the aperture diameter of the diaphragm and the lower it is, the more objective allow to pass the light to the sensor. The iPhone 6 is the least well equipped taking up only a 8 megapixel sensor assisted by a lens with an f / 2.2. The Apple device loses the battle of the figures face the Galaxy S6 and G4, but what about in practice
In an attempt to separate the three smartphones, we conducted a series of shots in order to create face to face. Each time, the LG G4 was compared to the Galaxy S6 and then to the iPhone 6. On each image, a cursor moving from left to right allows you to compare two photos.
Photo Applications
Before viewing the results in detail, let’s look quickly on the software part of the three smartphones. Clearly, the iPhone 6 is the most indented since it is impossible to switch to manual mode. But the automatic mode is very interesting since it is possible to independently adjust the focus of the exhibition. On the G4 and the Galaxy S6, one must be in manual mode and that’s a shame. However, the manual mode allows access to many settings: white balance, focus, ISO and the support DNG (RAW). The LG G4 can even support setting the shutter speed and it is rumored that Samsung intends to provide this support with next update of its terminal. Best of all, the G4 LG fully supports the API Camera2 and third-party applications will be able to take advantage of all these features, unlike terminals as the HTC One M9 using a proprietary API.
A word about the development speed. Sensors Galaxy S6 and iPhone 6 have both a phase-detect autofocus (unlike traditional contrast measurement). The G4, meanwhile, uses a laser autofocus and a color spectrum sensor. In fact, it is iPhone 6, which is the fastest to the development while the terminals LG and Samsung are difficult to decide.
The lemon pie
The meringue was well burned, that’s not a fault of the sensors. Here is the Galaxy S6 that manages to display the pie as it really appeared. The white balance is a little wasted on the G4 while issued photo iPhone 6 is a little too dark (remember here that it is easily possible to increase brightness on the iPhone).
The bouquet of flowers and cake
Here, the G4 unveils its main flaw overexposure pictures. The tart is clearly too bright and rendering that is closest to reality is that issued by the Galaxy S6.
Strawberries
Here, the color spectrum sensor G4 seems to prove itself with a well-adjusted white balance. He is ahead of the Galaxy S6 and iPhone 6 that deliver a cliché a little too cold.
The bouquet
Here is the iPhone dominates debates with an almost perfect white balance. The LG Unveils G4 too yellow picture when the Galaxy cliché S6 is a little dark
Cake. Retail 100%
We croppé the cake to the photo display 100% of its size. Here, we clearly see the lack of details of the iPhone 6, because of its 8-megapixel sensor. Instead, the 16-megapixel sensor is placed before the IMX240 sensor Galaxy S6. However, it is rare to have to display images of 8 or 16 megapixel 100% of their original size. But on prints, the LG G4 will fare better.
Night Scene
On this night scene, the LG G4 takes clear advantage against the Galaxy S6. The white balance is best handled at the terminal of Korean. Compared to the iPhone 6, the gap is closing on the white balance. However, the stability of non-Apple smartphone sensor fails him and the picture is not clear enough. Mode 100%, despite a stabilized sensor, Galaxy S6 is behind by the G4 on the retail level as can be seen on the crane or tag the wall.
Our opinion
In the end, hard to decide between the three terminals. Every smartphone has its advantages and disadvantages. The LG G4 conspicuous by its level of detail really stunning . However, the white balance is not quite constant in automatic mode. He asked to switch to manual to afflict mode. The Samsung Galaxy S6 is a little behind on the level of detail, but looks a bit more homogeneous on the rest including a fairly well controlled exposure, but a white balance on west night scenes. To address this flaw, a manual shift mode is necessary. Finally, iPhone 6 is clearly behind on the details, but it is the terminal that delivers colors often realistic.
Do not forget that the defects found on G4 LG and Samsung Galaxy S6 are easily correctable through the RAW (DNG). Just then import the photos into a development program like Lightroom and finely adjust the white balance, exposure, and a whole bunch of parameters to get the perfect shot.
If you simply use a social network / souvenir photos, the three terminals fully play their role. Only a little more sophisticated users will have to make a choice, and concessions. And ends with two macros made in manual mode with the LG G4. If you want to recover the DNG files, it’s here.
As an individual, the LG G4 me most marked with a truly ergonomic photo application and the possibility of really sharp pictures despite a blur behind very strong level, made possible by the opening of f / 1.8. In addition, the stabilized sensor made perfectly at night. It will, however, be prepared to change his photos with RAW processing software to correct small color errors.
