{options.map((option, index) => {
return ( setSelectedOptionIndex(index)}
/>
)
})}Code language: HTML, XML (xml)
```
In our`App.js`file, we first create a`const getImageStyle = useMemo`, which is going to contain the style we apply to our image. In our function, we created our`const filters = options. map`. This map loops through all of our options to get them converted to a usable CSS property.
We are now done with our demo photo editor app with React and CSS Filters.
Take a look at the practical results.
Here’s us modifying Brightness, Contrast, and Saturation:
[](https://coderpad.io/wp-content/uploads/2022/09/img_631f6f830e214.gif) A user changing the brightness of an image all the way down and back up, then doing the same with contrast and saturation. The CSS filters work the same way a traditional photo editing app would.
Now here’s an example of us modifying the Grayscale, Sepia, Hue Rotate, and Blur:
[](https://coderpad.io/wp-content/uploads/2022/09/img_631f6f877de1c.gif) The user is modifying different color properties, such as grayscale, sepia, and hue rotate. Then, they’re adding a blur to the final result.
Try out the photo editor in the sandbox below:
## Wrapping up
Wow! We’ve learned quite a bit just by creating a simple photo editing application that uses CSS filters to apply different effects to an image.
If you want to see the full source code for the React application we built today, you can see the source code over [on my GitHub repository containing the project](https://github.com/uma-victor1/photo-editor).
Once you’ve mastered CSS filters, you’ll likely want to use them in combination with CSS math functions throughout your app’s styling. [Here’s an article outlining what CSS math functions are, and how to use them](https://coderpad.io/blog/development/an-overview-of-five-css-math-functions/).
Lastly, as you continue to expand your React photo editor, you’ll need a way to show your users different pages based on the URL. [Here’s how you can add in a routing solution into React](https://coderpad.io/blog/development/guide-to-react-router/).
Hopefully this article has been helpful in learning how to practically apply CSS filters and build an app of your own. Until next time!
