PhotoShop In The Browser: Understanding CSS Blend Modes

tools / photoshop

Estimated reading time: 4 minutes, 45 seconds

blend modes are arriving in via the new blend-mode and background-blend-mode properties. Values for the properties – lighten, multiply, hard-light, etc – are exactly the same as those in Adobe applications. It’s been my experience that relatively few people understand what blend modes are exactly, even among those who use Photoshop on a daily basis. In practice, it’s usually a case of choosing a particular mode because the result “looks right”.

We don’t want to carry that state of ignorance into web development. In this article, I will illustrate what the basic blend modes are and how they work, with the goal of killing two birds with one stone: whether you’re interested in or want to play with CSS blending, what follows should be helpful regardless.

500pxApplying an automated sequence of operations to a set of images is known as “batch processing”.  Batch processing is typically used to create a series of thumbnails for a gallery, or interchangeable banner images, or headshots for the profile page of a board of directors. In this tutorial we’re using the first example, but in all cases, the final images need to be the same size and aspect ratio. I’ll be using images from 500px.com, my newest favourite photography site: the photographs are by Mike Orbinski, Dale Martin, and Tom Lowe.

For a real-world example, you would want your source images to be as high a resolution as possible, and in a lossless format, in order to preserve the highest quality possible during our workflow.

In PhotoShop we wish to execute two steps:
