 What are the differences between the various sharpness settings of the Insta360 ONE RS camera? You can choose between **Low**, **Medium**, **High** and **Very High** sharpness, but what is the best choice?
-Let's start saying that **[[https://www.urbandictionary.com/define.php?term=pixel%20peeper|pixel peeping]]** is not the best practice to choose the preferred sharpness, neverthless we start by showing a **200% enlargement** of a **4K frame detail**, to explain how the sharpness filter works. **Sharpening filters** are a type of image processing that enhances the contrast between neighboring pixels, making the edges and details more visible and defined.

-===== Low =====
+===== Low Sharpness =====
-With a //low// setting of the sharpness, the image details look soft, but beware that this belltower roof is just a small detail of the entire 4K frame (see below for the full image). Consider that you may want to soften the image on purpose, e.g. to **hide the skin imperfections** of a person in a close-up shot.

In the second detail you can see how the foliage is rather blurred. Consider that you may want to soften the image on purpose, e.g. to **hide the skin imperfections** of a person in a close-up shot.

-===== Medium =====
+===== Medium Sharpness =====
+At medium sharpness the **details of foliage** may be still too blurred, but you have to check the overall effect instead of check the single pixel.

-===== Very High =====
+===== High Sharpness =====
-You need the //very high// sharpness setting to see the **lightning rod** on the roof of the belltower, but the pattern of the stones becomes by far less natural.
+With the **high sharpness** setting, the sharpness is increased by adding a bright **halo** around dark areas and vice-versa.

+===== Very High Sharpness =====
+You need the //very high// sharpness setting to see the **lightning rod** on the roof of the belltower, but the pattern of the stones becomes by far less natural. Also look at the edges of the **car window**: the contrast between the light and dark areas has been increased a lot in an unnatural way by the software filter.

+You are encouraged to view the full frame at whatever enargment you expect to see your footage. I think that generally you may want to choose **medium** or **high** setting.
