 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.
