With full manual exposure control and the ability to save images as raw files, the Canon PowerShot S90 may be the perfect compact camera for the demanding enthusiast photographer
LCD, live view and video
With no optical viewfinder, the S90 user is reliant on its 3in, 461,000-dot LCD screen when composing images. Although traditionalists may dislike the lack of viewfinder, if the viewfinder on the PowerShot G11 is anything to go by the S90 isn’t missing out.
During my test of the S90 I didn’t come across any problems with the screen. It is large and bright, and shows enough detail so it is possible to check images for details and sharpness.
The brightness of the live view preview changes to reflect how your image will be exposed and saved. This is useful should you be in a manual exposure mode or wish to use the EV compensation to adjust an exposure.
When adjusting the exposure compensation in video mode, the view on the screen also represents how the final footage will look. However, the exposure cannot be changed once video capture has started.
