Canon PowerShot A3400 IS Review

Image Quality

All of the sample images in this Review were taken using the 16 megapixel Fine JPEG setting, which gives an average image size of around 4Mb.


Image quality from the Canon PowerShot A3400 IS is very good. We managed to get goods results consistently throughout the test regardless of the situation we put the camera into. At low ISO, the pictures are crisp and clear with lovely colours and - more importantly - no colour noise showing through at all. OK, so if we were to be harsh, there's some JPEG artefacts that can be seen at full magnification but it is only a point and shooter which is easy to forget when faced with such quality pictures. The good news is that you can push the sensitivity settings up to the next level and at ISO 200 the quality doesn't change.

There's a slight nosedive at ISO 400 but it has to start somewhere and the mid-levels isn't a bad place. However, edge definition is still good at ISO 400. That doesn't start to suffer until ISO 800 where colour noise is becoming more prevalent. Interestingly, Canon have taken the decision to cap the ISO settings at ISO 1600.  Judging by the results of our test, it's a good idea. Colour noise is still being controlled by the camera but we think that pushing to ISO 3200 would simply exacerbate the problem and the struggling noise reduction software would be overwhelmed.

Despite the Canon PowerShot A3400IS producing sharp and detailed photographs, they do benefit from a zap of sharpening using an editing suite such as Adobe Photoshop.

Chromatic Aberrations

Although we struggled to find instances of chromatic aberration, that's not to say it isn't present. We found it mainly at the edges of the frame and in very high contrast areas.

The Canon PowerShot A3400 IS has a 3cm macro facility which allows you to get in nice and close to your subject. There's a degree of edge definition fall off around the centre of the frame but that's to be expected.

With or without flash there's an element of vignetting at the corners of the frame with the A3400 IS. Using flash does alleviate the problem to a degree, but not fully.

In the portrait images, red-eye seems to be present on both images. However it looks worse as a smaller image than at full magnification. This is due to a red ring around the flash catch-lights which could be red-eye or chromatic aberration. It's difficult to tell but if it's the latter, it spoils the picture and red-eye reduction software won't be able to compensate for that.

Night Shot

There's little difference between the program setting and Night scene setting in terms of image quality. However, the Night mode allows slightly longer shutter speeds to give a lighter image.
