LG G4 Review

Image Quality

All of the sample images in this review were taken using the 16 megapixel JPEG setting, which gives an average image size of around 5Mb.

Directly from the camera, JPEG images display a good level of vibrance and clarity, perhaps being a little too saturated to be completely accurate but never-the-less giving a great effect. It would have been good if you could choose different shooting modes to bring down that saturation a little.

As you can shoot in raw (DNG) format, it’s possible to see how much processing is applied to JPEG images. By contrast, the raw files are much less saturated, aren’t quite as sharp and there’s more noise. This is good news for photographers who want to take advantage of image editing software, to keep exactly the amount of detail they want, for instance.

Low light capability is good, if not quite as amazing as LG likes to claim. In the middle of the sensitivity range, such as ISO 800, noise (in JPEG) images is barely apparent, while if you go further up the range it’s difficult to see much example of noise unless you examine at 100% - something which seems to be unlikely for the majority of users of this camera.

The LG G4’s automatic white balance setting does well, even when faced with artificial lighting conditions. Similarly, the camera’s all-purpose metering system produces accurately exposed conditions in the majority of conditions.

Noise

Here are some 100% crops which show the noise levels for each ISO setting for both JPEG and RAW formats:

Focal Range

The LG G4's lens provides a focal range of 29mm in 35mm terms, as demonstrated below.

Sharpening

Here are two 100% crops which have been Saved as Web - Quality 50 in Photoshop. The right-hand image has had some sharpening applied in Photoshop. The out-of-the camera images are a little soft at the default sharpening setting and benefit from some further sharpening in a program like Adobe Photoshop.

Chromatic Aberrations

The LG G4 handled chromatic aberrations fairly well during the review, with some purple fringing mainly present around the edges of objects in high-contrast situations, as shown in the examples below.

Chromatic Aberrations 1 (100% Crop)

Chromatic Aberrations 2 (100% Crop)

Macro

The LG G4 offers a Macro setting that allows you to focus on a subject that is 5cms away from the camera.

Flash

The flash settings on the LG G4 are Off, On and Auto. These shots of a white coloured wall were taken at a distance of 1.5m.

And here are a couple of portrait shots.

Panorama

The LG G4 allows you to take panoramic images very easily, by 'sweeping' with the camera while keeping the shutter release depressed. The camera automatically does all the processing and stitching.
