Canon PowerShot A510 - Digital Camera - Test Shots - Full Res Crops
A range of test shots are shown over the next two pages. Here, the full resolution image has been reduced in size for bandwidth purposes, and a crop (taken from the original full resolution image at Adobe ImageReady jpg quality 60) follows each image in order for you to gain an appreciation of the overall quality. The next page consists of resized images (to Adobe ImageReady jpg quality 50) so that you can evaluate the overall exposure. For those with a dial-up connection, please be patient while the page downloads.
Despite the surrounding foreground object, the A510’s AiAF autofocus system has correctly focused on the trees in the background.
Switch to macro mode and the camera correctly focuses on the foreground object, despite the fact that it isn’t in the centre of the frame.
Using aperture priority exposure and setting an aperture of F2.6 gives this photo a narrow depth of field, blurring out the background.
At the lowest setting of 50 ISO there is no visible image noise on this shot, although the sharpening is a little harsh.
One stop up and at 100 ISO the image is still a noise-free zone, so please turn off your mobile phone.
At 200 ISO a tiny amount of image noise is creeping into the darker areas, but you can only notice it relative to 50 ISO.
At the maximum 400 ISO there is quite a bit of noise, but it is very well controlled and the image is still quite usable.
