The screen display in the Automatic record mode. Icons across the top and left indicate that metering is Evaluative, single frame drive, auto ISO, auto flash, and Auto exposure mode. The image size is Large, quality is SuperFine and there's space left on the SD card to take 932 more pictures.

When the color LCD is turned on and you half-press the shutter you will see which of the nine AF points (green rectangles) were used for the focus lock. The aperture and shutter speed values are also shown along the bottom.

Manual exposure mode is like Auto in that the camera selects both the shutter speed and aperture for a correct exposure but you now have access to a multitude of Function and Menu options.

To set long shutter speeds, enter the Function menu, highlight exposure compensation then press the Menu button. The shutter speed is displayed at the bottom of the LCD; select a value from 1 to 15 seconds using the left and right buttons of the 4-way controller. Depress the FUNC./SET button to return to shooting mode. The LCD viewfinder's live image provides a preview of the exposure; adjust the shutter speed for the exposure you want. Noise Reduction is applied for exposures of 1.3 seconds or longer.

The camera has a very respectable macro focusing mode with coverage from 1.2 in.- 1.6 ft./3-50cm (WIDE), 1 - 1.6 ft./30-50cm (TELE).

Scene modes are selected via the Function Menu. You can choose from 13 different modes. These are pre-programmed to give you the best possible pictures for a wide variety of different shooting situations. In all Scene modes, Exposure compensation, Image compression and Image size settings are available via the Function menu.

The Stitch Assist Panorama mode is available from the Function menu with the Mode dial in Manual. It aids you via on-screen prompts to achieve the proper overlap of sequential photos for later "stitching" with the PhotoStitch program. You can capture up to 26 images in either left-to-right or right-to-left orientation. After the first picture is taken the white balance and exposure is locked until you exit the StitchAssist mode.   The use of a tripod and a bubble level is recommended. Since the SD750 will not output video in this mode, this screen capture was taken from the PowerShot S400 review.

You can record movie clips with audio at a variety of resolutions and frame rates. Standard movies can be recorded at resolutions of 640x480 or 320x240 with frame rates of 30 or 15 fps. You can also choose from Compact (160x120, 15fps), Fast Frame rate (320x240, 60fps), Color accent, Color swap, and Time lapse (640x480, 1 or 2fps) modes. The optical zoom may not be used during recording, but can be preset before hand. These clips are captured in Motion JPEG format and saved as AVI files.

Both the video and audio portion of movies can be replayed on the camera thanks to the built-in speaker. Full audio-video playback is also possible when connected to a TV monitor or a compatible PC after downloading.
