Canon PowerShot S40 Review
Record mode display
Here, an example of information overlay in Program Auto Exposure mode. Camera settings are shown down the left hand side of the display. Along the bottom are image quality and focus mode settings.
In this case: Flash Cancel, Single Shot, Evaluative metering, Cloudy White Balance, +0.3 EV compensation, Super-Fine Large quality, Macro Focus, 242 frames remaining.
|Here we're already half-pressed the shutter release and are ready to shoot. Notice the exposure is now displayed and that the selected AF frame has turned green to indicate a good focus (it would turn yellow if the AF couldn't lock). Also, because the exposure is slow it may suffer from blur (due to hand shake) so the small shake icon is displayed.||After shooting a preview is displayed briefly (this can be disabled or set to 2 or 10 seconds). During this preview you can press the MF (erase) to delete the image or the meter (microphone) button button to record a voice annotation (up to 60 seconds). **|
|Press the DISPLAY button and you can use a 'clean' viewfinder view, the only details displayed are the focus mode and AF frame.||Pressing the SPOT meter button adds these square [ ] brackets to the center AF frame, these indicate the total frame area used for metering.|
|Example of Shutter Priority (Tv) mode, shutter speed is displayed and aperture will be calculated on a half-press of the shutter release.||Example of Aperture Priority (Av) mode, aperture is displayed and aperture will be calculated on a half-press of the shutter release.|
|The new 'Colour Effects' exposure mode.||Example of movie clip record mode, the number of seconds remaining (1972 in this example) simply refers to the total space, an individual clip is limited to either 30 secs (320 x 240) or 120 secs (160 x 120).|
** Note: it is possible to change this to a histogram display by pressing the SET button to hold the image on the screen then press DISPLAY to switch to histogram mode. All shots taken from then onwards will use a histogram display for image review.
On P, Av, Tv or Manual exposure modes pressing the SET (AF Frame) button displays the three AF frame positions, you can now select which frame you would like to use for focusing by pressing the left/right arrows and then SET.
All other exposure modes use AiAF focus point selection (automatic).
An example of manual focus, unfortunately for some reason the central magnification isn't activated for video output (which we used to capture this image). Normally the central portion (about twice the size of the AF frame) is magnified to show more clearly where the focus point is. Note the new ruler indicating the focus distance in both metric and imperial distances.
|Switching to play mode immediately displays the last image taken. Depending on the previously chosen display mode you'll either see this (clean image, no info overlaid)||Press DISPLAY to increase the information displayed: folder / filename, frame number, image quality / size, date / time.|
|Press DISPLAY again to switch to the histogram / highlight mode. Here we can see far more exposure information as well as an exposure histogram and overexposed areas of the image are flashed on and off.|
|In Jump mode you can skip through 10 images at a time without switching to thumbnail view mode.||Thumbnail view, 3 x 3 images displayed, you can use the 4-way controller to move the selector rectangle between images. Note that movies are indicated by the filmstrip side graphic.|
|Zoom, first level (3.0x). Use the 4-way controller to smoothly scroll around the image.||Zoom, second level (6.0x). Use the 4-way controller to smoothly scroll around the image.|
|Selecting the Rotate option from the play menu allows you to rotate the displayed image through 90 degrees. The rotation is recorded in the image header (for in-camera display) but doesn't actually rotate the image file.|
