The G16's automatic white balance does a good job of producing accurate colours in mixed lighting conditions, but metering has struggled slightly here, making the subject slightly underexposed.
The G16's maximum aperture if f/1.8, making it ideal for use when shooting portrait images.
Colours straight from the G16 are bright and punchy, with a good level of saturation and accuracy in subjects such as skies.
At its widest point, the G16 offers an equivalent of 28mm, making it ideal for capturing a good variety of subjects. Canon's S120 goes slightly wider at 24mm, though.
Here, despite the high-contrast nature of the scene, chromatic aberration isn't visible even when zooming in at 100%. There is a fractional amount of fringing, but it's not noticeable at normal printing and web sizes.
The G16 features 5x optical zoom. Here's a picture shot at the widest point of the lens - 28mm equivalent.
This image was shot at the telephoto end of the optic, which offers an equivalent of 140mm. Impressively, even at this far reach of the telephoto optic, the lens is still able to stop down to f/2.8.
Canon's ZoomPlus technology is available to boost the zoom's capability up to 10x. Detail is retained impressively well here, making it a viable option if you do need that extra bit of reach.
Standard digital zoom is also available, to push the zoom capability up to 20x. There's less detail here, but again, if you really need to get closer it's a nice option to have, especially if you're only sharing images online.
The G16's macro focusing capability allows you to get very close to the subject to fill the frame with detail rich close-ups.
The G16's f/1.8 aperture allows you to get creative with shallow depth of field effects.
Shooting at mid-range apertures, such as f/8 allows us to determine the sharpness of the camera's lens. Here we can see that the image is reasonably sharp throughout the image, with some evidence of loss of detail in the corners when zooming at 100%. At normal printing and web sizes however, detail is kept well.
A number of digital filters are available to use on the G16, accessible via a dedicated mode.
Filters are as follows:
