+ | ===== i-Contrast ===== | ||
+ | |||
+ | **i-Contrast** is a **post-processing filter** applied by the S120 after the shoot. It can be applied at **shoot time** (supposedly on the RAW image) using two different pre-sets (see below), or it can be applied on the JPEG image **in play mode** using four modes. | ||
+ | |||
+ | Applying i-Contrast in **play mode** is rather pointless, just **use your preferred photo editing software** to get better control on the exposure. Using i-Contrast at **shot time** can perhaps get better results **if it actually operate on the RAW image**: adjusting the exposure **before JPEG compression** can lead to better results than post-processing on the JPEG image. But actually **we don't know how i-Contrast operates at shot time**, so - if you have any concerns about a bad exposition - just shot in RAW mode and do post-processing in your preferred software. | ||
+ | |||
+ | One user in this [[https:// | ||
+ | |||
+ | Anyway, in **P mode** you can activate **i-Contrast** in two modes: | ||
+ | |||
+ | * **Dynamic Range Correction**: | ||
+ | * **Shadow Correct**: to preserve image in shadows | ||
+ | |||
+ | In playback mode you can instead apply **i-Contrast** in four variant: **Auto**, **Low**, **Medium** and **High**. Whatever it means! | ||
+ | |||
+ | ===== Image Stabilization (IS) ===== | ||
+ | |||
+ | The Canon S120 features lens stabilization, | ||
+ | |||
+ | * **Continous**: | ||
+ | * **Shoot Only**: applied only at shoot time | ||
+ | * **Off**: disabled | ||
+ | |||
+ | If you choose // | ||
+ | |||
+ | ==== Dynamic IS ==== | ||
+ | |||
+ | For **movies recording**, | ||
+ | |||
+ | You can enable or disable the software image stabilization for videos from **IS Settings** menu, **Dynamic IS**: | ||
+ | |||
+ | * **Option 1**: enable software stabilization, | ||
+ | * **Option 2**: disable software stabilization (use only lens stabilization), | ||
+ | |||
+ | The resulting video - when software IS is active - is **scaled** (**enlarged**) by the camera software, so that **the resulting size is the same** as per video without software IS. This means, for example, that a Full HD video will be 1920x1080 pixel regardless of the software IS setting, but our test revealed that **the actual area of the video is reduced by 12%** in both width and height. | ||
+ | |||
+ | ===== Manual Focus ===== | ||
+ | |||
+ | * Manual Focus (**MF**) is available in **P**, **Tv**, **Av** and **M** modes. | ||
+ | * Press **[Left/ | ||
+ | * Press **[Up]** or **[Down]** on the //control dial// (or rotate it) to adjust the focus. | ||
+ | * Press **[Right]** on the //control dial// to change zoom magnification. | ||
+ | * If **Peaking** option is **On**, edges in focus area are colored in red. See [MENU], camera tab, **MF Peaking Settings...**. | ||
+ | * Press **[MENU]** if you want to enable **Focus-BKT**: | ||
+ | * Press **[FUNC./ | ||
+ | * If the **Safety MF** option is **On** (see the [MENU], camera tab): | ||
+ | * Move the **focusing frame** (orange rectangle) tapping the touch screen. | ||
+ | * Press **halfway the shutter button** to **refine the focus**. Warning! The instruction manual talks about // | ||
+ | |||
+ | |||
+ | ===== Safety Shift ===== | ||
+ | |||
+ | **Safety Shift** is an option that interferes with manual settings in **Tv** and **Av** modes. | ||
+ | |||
+ | Pressing the **shutter button halfway** will show the aperture value or the shutter speed **selected automatically to obtain a standard exposure**, if such exposure cannot be obtained, the value is displayed in **orange color**. But if **Safety Shift** is enabled, the manually selected value (aperture or speed) will be corrected and displayed on the screen. To enable this option, press the **%%[MENU]%%** button and search the **%%[Safety Shift]%%** into the //camera tab//. | ||
+ | |||
+ | ===== Neutral Density Filter ===== | ||
+ | |||
+ | In photography, | ||
+ | |||
+ | For example you can use it to allow an **high aperture value** and get a **lower depth of field**. | ||
