The [Orton Effect](https://www.capturelandscapes.com/orton-effect-explained/) is a photography technique that involves taking two pictures of the same scene, one with a long exposure and one with a shorter exposure, and then combining them. The result is an image that has both the sharpness of the long exposure and the detail of the shorter exposure. While it's not an exact replica, we can simulate a phoo filter for the Orton Effect using CSS and React.

## Emulating the Orton Effect in CSS

To emulate the Orton Effect in CSS, we need to layer 2 copies of the same image on top of one other. To accomplish that, we'll nest them under a single parent - in this case, the [`figure` element](https://developer.mozilla.org/en-US/docs/web/html/element/figure). Note that for the second image, we set [`aria-hidden=true`](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Attributes/aria-hidden), and intentinally set `alt` to an empty string, so that Screen Readers and other visual assistive tools skip them. won't encounter the repeated image element. You can read more about that and other accessibility features of HTML on [MDN](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Attributes/aria-hidden).

```html
<figure class="orton-effect">
  <img
    src="https://source.unsplash.com/tRDGs9utMUo/1600x900"
    alt="A man in the crosswalk on a city street"
  />
  <img
    src="https://source.unsplash.com/tRDGs9utMUo/1600x900"
    aria-hidden="true"
    alt=""
  />
</figure>
```

Next, we'll use a CSS rule to apply some styles to the _first_ of the two images (in HTML-speak, that's the one on top).

```css
figure.orton-effect img:first-of-type {
  position: absolute;
  mix-blend-mode: lighten;
  filter: blur(50px);
  opacity: 50%;
}
```

We're setting `position: absolute;` to layer this image on top of its sibling within the `<figure>` element. The remaining 3 lines of CSS set the top image to use the `lighten` blend mode, apply a gaussian blur using `filter`, and make the top image partly translucent by way of the `opacity` CSS property.

This creates a hazy, glassy effect:

### Before:

<img
  src="https://res.cloudinary.com/mikebifulco-com/image/upload/v1662995195/posts/orton-effect-css-react/crosswalk.jpg"
  alt="A man in the crosswalk on a city street"
/>

### After:

<OrtonEffectImage
  src={
    'https://res.cloudinary.com/mikebifulco-com/image/upload/v1662995195/posts/orton-effect-css-react/crosswalk.jpg'
  }
  alt="A man in the crosswalk on a city street"
  blurRadius={50}
  opacity={50}
/>

It's subtle - but it is there, adding just a slight haze over the light parts of the photo, like a morning fog settling in over a dreamscape.

## The Orton Effect in React

To apply this to an adjustable React Component, we'll use CSS-in-JS to make blur and opacity dynamic. There's many ways to get this done, of course, so you may prefer a different approach. This is what a simple react component for this layout might look like:

```jsx
const OrtonEffectImage = ({ alt, blurRadius, opacity, src }) => {
  return (
    <figure>
      <img
        src={src}
        alt={alt}
        style={{
          mixBlendMode: 'lighten',
          filter: `blur(${blurRadius}px)`,
          opacity: `${opacity}%`,
          position: 'absolute',
        }}
      />
      <img src={src} ariaHidden alt="" />
    </figure>
  );
};
```

This gives us a reusable component that just needs a few parameters passed in - for example:

```jsx
<OrtonEffectImage
  src={
    'https://res.cloudinary.com/mikebifulco-com/image/upload/v1662995539/posts/orton-effect-css-react/snowy.jpg'
  }
  alt="A snowy landscape"
  blurRadius={30}
  opacity={70}
/>
```

Note that a few things have changed here - we're no longer using a named CSS class (`.orton-image`) to select and modify images via CSS. The CSS is now specified on the `img` tag itself, and because it is passed in via `style` prop, it is a JavaScript Object -- so keywords have gone from skewer-case to camelCase, and there's commas where we once had semicolons. Additionally, we're using ES6 String templates to interpolate style rules from the opacity and blur radiuses passed in.

There's some improvement to be done from here - you should do some error checking to make sure that opacity stays between 0 and 100%, and that the blur radius is a positive integer. It's also a good idea to provide some sensible fallback values for those options, in case they're not provided. I'll leave that up to you to implement.

## The Orton Effect in Action

Below you will see the Orton Effect applied to a handful of other images from Unsplash.

I've taken the above example a little further, and made blur and opacity adjustable, so that you can see how each parameter changes the image effect.

I've found that an opacity of somewhere between 25 and 50% and tends to create a nice, subtle effect. The "right" blur radius is a bit more dependent on the specific image.

<OrtonEffectImage
  src={
    'https://res.cloudinary.com/mikebifulco-com/image/upload/v1662995539/posts/orton-effect-css-react/snowy.jpg'
  }
  alt="A snowy landscape"
  blurRadius={30}
  opacity={70}
  showControls
/>

  alt="A scene at a local cafe"
  blurRadius={30}
  opacity={70}
  showControls
/>

<OrtonEffectImage

  blurRadius={30}
  opacity={70}
  showControls
/>

## Summary

The Orton effect is a photography technique that involves taking two images - one in focus and one out of focus - and overlaying them to create a third image with a dreamy, ethereal quality.

It turns out that this effect can also be simulated using CSS and React! All you need is a bit of code to overlay two images and some CSS to blur one of the images.

If you're looking to add a touch of magic to your photos, then recreating the Orton effect with CSS and React is a great way to do it.

<Aside type="note">

This is an experimental post, meant to demonstrate to you the topic we're discussing. I'd love to hear what you think about it. [Drop me a line](https://twitter.com/irreverentmike) if you find this compelling - I'm hoping to create more like it!

</Aside>

<CenteredTextDemo>

This is -- without exception -- my biggest design-related pet peeve. You've probably come across it yourself from time to time, and if you're lucky, it's not something you noticed. Centering text on a web site, email, or flyer is an easy way to make it appear like a designer's spin has been put on a document. It's an easy change to make in most editors, and in many cases it's probably done without a second thought.

I'll cut to the chase: _center-aligning text is really bad_ in most cases. From a young age, we're trained to read text by starting at the beginning of the line and moving our eyes across the page to the end of the line. From there, it's a relatively low-effort thing to move your eyes back to the beginning of the next line. That all changes when text is centered, since the start of each line is aligned inconsistently. It takes more effort to find the beginning of the next line, to make sure you've only moved down _one_ line, and to continue reading.

## Three great reasons you shouldn't center-align text:

1. A ragged leading-edge makes it harder to move your eyes to the next line of text
2. People with dyslexia may find centered text challenging to read.
3. Lists (like this one) become disorienting to read, and harder to scan

The British Dyslexia Association provides a <a href="https://www.bdadyslexia.org.uk/advice/employers/creating-a-dyslexia-friendly-workplace/dyslexia-friendly-style-guide" target="_blank">dyslexia-friendly style guide</a>, which calls out a simple rule for text:

<Aside type="note">Left align text, without justification.</Aside>

As a designer, this is _such_ an easy win. As a developer, it's often as easy as:

```css
/* change this */
.some-style-rule {
  text-align: center;
}

/* ...to this! */
.some-style-rule {
  text-align: initial;
}
```

## When you _can_ use centered-text

Generally speaking, if you're certain that your text will fit on _one line,_ it may be okay to center it. This generally applies to page titles, captions on pictures, and things of that nature. Even then, generally speaking my guidance is to avoid it. Like many other things in design, if there's not a good reason _to_ do it... you're better without.

## Summary

If you're working on a design that relies on centered text, consider other options. If you come across a big blob of centered text in your workplace, or out in the world somewhere, please feel free to use this post as a demo.

Don't center align paragraph text


I often joke that to learn about design is to doom yourself to be lightly annoyed by everything. After some repetition, you'll start to internalize some of the basic rules of industrial design, or print design, or fashion design, or mechanical design, or whatever it is that gets you excited. You'll start to find design quirks in the world which were once hidden to you. After all, every single thing in the built environment has been put there by someone who took their time to bring it to life. The downside, of course, is that you'll also start to see designs that downright suck. I find that it's helpful to think of it as finding opportunity for improvement.

Today's opportunity for improvement is brought to you by [Wikipedia](https://en.wikipedia.org/wiki/Ralph_Waldo_Emerson), which had me going cross-eyed as I read through an article in the early hours of this morning.

<Image
  publicId="posts/all-about-ch/wikipedia-4k"
  alt="Screenshot of a wikipedia article on a wide monitor. Text spans fully from left to right, taking up the full width of available space."
  caption="A fullscreen desktop view of wikipedia on my 4k monitor."
/>

## What is a ch, and why you should c(h)are

It's simple, actually - ch is a CSS unit which represents the width of a character! If you're using a proportional font (where not all characters are the same width), 1ch is the width of the 0 character in the typeface you're using. This is particularly helpful for usability as it relates to reading long passages of text.

## Line length and reading usability - err, readability

Limiting the line width for text in long passages is a great tool for making things more readable. [Studies have shown](https://baymard.com/blog/line-length-readability) that for optimal reading, text should be limited to somewhere around 60 characters per line. Think about it - this is why paperback books are generally smaller than an A4 page. This is why people love reading on their kindle. This is why Barnes and Noble sells Nooks like hotca — well, it's why the Nook is shaped like it is, at least.

In practice, what does this look like? Let's take that same wikipedia article and limit its paragraphs to 60 characters:

```css
p {
  max-width: 60ch;
}
```


Here's what it looks like:

<Image 
  publicId="posts/all-about-ch/wikipedia-ch-applied"
  alt="The same wikipedia article with a limit set on p max-width for ch yields a page that is much easier to consume visually, and is more readable."
  caption="Column width adjusted using the CSS ch unit."
/>

Okay, so that's not a fully-baked design update, but with a few tweaks we can make it a little nicer by bumping up the font size, and adjusting the layout of the right-hand column (side note: wikipedia uses float: right on that column, surprisingly!)

<Image 
  publicId="posts/all-about-ch/wikipedia-ch-adjusted"
  alt="With a few additional layout tweaks, the page can be reflowed around the ch-limited paragraphs, making the entire article more coherent and easier to read."
  caption="Font size bumped up, and right-hand column adjusted to snap in place next to it.  Much easier to read!"
/>

That's not bad at all! One of the nice things about using a character **count** for setting the width of that section is that it scales nicely for folks who use the browser's zoom functionality. You can also put your text passages inside of pixel-size-limited divs to make them work in responsive layouts at smaller sizes:

```html
<style>
  @media screen and (min-width: 800px) {
    .blogpost {
      max-width: 400px;
    }
  }
  .blogpost p {
    max-width: 60ch;
  }
</style>
