The fourth crop, from the centre of the image once again shows good sharp image details, an absence of noise and generally a very pleasing and natural looking result that betray no evidence of digital processing. It’s not the end of the world, though to find it on a shot like this in a fairly low contrast area of a shot taken with the sun behind the camera and at a small aperture, does raise the chances of it occuring at wider aperture settings and when shooting into the light. The third crop, taken from the edge of the frame is the first sign of any real trouble, there’s quite pronounced purple fringing caused by chromatic aberration. The detail in the foreground of this crop is also nice and sharp too, though, once again, there’s a slighly granular look to the flat blue sky. ![]() Despite that, the PowerShot A800 has done a pretty good job of picking out the white cylinder of the lighthouse. On the second crop the lighthouse isn’t as visible as it sometimes appears, but that’s due to the fact that it was quite a hazy day. There’s some noise visible in the blue sky but it isn’t serious enough to interfere with image detail. The first one shows good fine detail in the chapel, you can clearly make out a couple of people outside and the crosses on the roof are nicely delineated. The 100 percent crops are equally impressive. Looking at the whole image on screen at less than 100 percent view the image is crisp, clear and well detailed. The exposure is spot on, colours are bright and well saturated and there is good tonal detail in the shadows and highlights. Overall, the PowerShot A800 has done a great job of capturing our test scene. The crops are taken from the areas marked with red rectangles and are presented here at 100%. The original 3648 x 2736 pixel image had a file size of 3MB. The lens was set to its maximum wide angle setting of 6.6mm (37mm equivalent) and the metering selected an exposure of 1/200 at f9 with the sensitivity at 100 ISO. The above image was taken with the Canon PowerShot A800. The Nikon COOLPIX doesn’t allow manual setting of the ISO sensistivity but, in the bright sunny conditions automatically selected 80 ISO. ![]() The ISO sensitivity on the two Powershot compacts was set to the lowest available setting – 100 ISO on the PowerShot A800 and 80 ISO on the PowerShot A1200. The lenses on each camera were set to approximately the same field of view, the PowerShot A800 and PowerShot A1200 were set to Program mode and the Nikon COOLPIX L24 was set to Auto. To compare real-life performance when zoomed-out, we shot this scene with the Canon PowerShot A800, PowerShot A1200 and the Nikon COOLPIX L24 within a few moments of each other using their best quality JPEG settings. ![]()
