Prisma: The Rise and Fall and Rise of the One-Trick-Pony Filter

By Alex Walker

Back in the early days of Photoshop – let’s call it ‘BC’… ‘Before CS‘– third-party image filters were considered really important. Your Photoshop install was considered virtually naked without a copy of Kai’s Power Tools and Alien Skin Eye Candy.

But this was also the golden era of what I’m going to call the ‘one-trick-pony’ filter. These were photoshop filters designed to deliver one very specific effect usually in one very specific way. Classic examples of one-trick filters include:

  • The Page Curl Filter
  • The Jigsaw Puzzle Filter
  • The Posterizer Filter

Page curl - jigsaw - posterize filters

Page Curl, Jigsaw and Posterize. ‘One-Trick-Pony’ Filters

These filters were sometimes fun – but were they of any genuine, practical commercial use?

No. Not really.

With little control over the output, the results were inflexible. More importantly, the design demand for jigsaw effects and page curls was no higher than it is today – close to zero. I like to compare these one-trick pony filter with this little beauty–it’s called the Fox Run Banana Slicer.

Banana Slicer

If you need to cut a banana of a certain size into precise, 10mm slices, boy, this baby can save you literally seconds! Caveat: If you need thinner or thicker slices or insist on working with rogue, non-standard bananas, the Fox Run may not be for you, my friend!

Like the Banana Slicer, one-trick filters never really caught on in the design community. Just as no professional chef would be caught using a banana slicer, no self-respecting designer would use a one-trick-pony filter. Ever.

Or… that’s what I believed until Prisma came along – now I’m not so sure.

So, what is Prisma?

Prisma is a phone app – iOS and Android – designed to apply image filters to your photos. It’s basically a glorified Instagram filter.

It offers very few adjustment controls. There’s little skill or genuine artistic expression. You pick a filter and hit ‘Go’. Prisma is, by any reasonable measure, a set of one-trick-pony filters.

I should hate Prisma. I want to. But I don’t.

Let’s have a look at what it can do. Firstly, Prisma is free and offers 29 different filter effects with arty names like Heisenberg, Traverse Line, Gothic, Mosaic, Illegal Beauty and Red Head.

I’m going to start with a photo I took recently and demo just two filters. You can make your mind up after that.

The original photo

This first Prisma filter is called ‘Heisenberg’ and it has a hard, almost woodcut print look.

Traditionally woodcut prints were made with carving tools that tended to dig out imperfect curves in the surface of the wood. The Heisenberg filter echoes these grooves.

It’s scratchy and hard-bitten but also has an artisanal, humanist edge that could work on an architectural, urban social work or fiction writers theme.

Here’s the same photo treated with a Prisma filter called ‘Composition’. It’s a very different look to Heisenberg, but, a fresh and powerful image in its own right. I can’t claim much credit for creating it, but I genuinely like it.

‘Composition’ gives the image a super-hip, 50’s jazz feel. I could see this treatment being used in a music or event zine to develop a really strong visual signature.

Look at the edges on the manhole cover and the shapes on the foot. I think it’s impressive.

How Does it Work?

Although Prisma works through a phone app UI, the image processing seems to take place on Prisma’s servers. It takes a while too - sometimes 20-30 seconds to return a photo and often not at all if the server is over capacity. One-trick-pony or not, it appears that Prisma needs a mountain of computing power to do these image translation.

Most of these filters reference either an art style (comics or pen sketches) or a particular artist (Lichtenstein or Picasso), but they aren’t slavish copies.

Look closely at the examples above and you’ll see Prisma has made some really clever color and line decisions - which lines to remove, which lines to emphasize, which colors to contrast. The thinking that drives the algorithms behind Prisma is clever and subtle.

Part of me hates to say it, but Prisma is pretty cool. It probably won’t make your bad photos good, but it can take your good photos somewhere new and eye-catching.

Yes, it’s true that, ultimately, Prisma is a stable of one-trick-ponies.

But gee, it’s a good trick.

    I think you are being unduly critical of the Fox Run Banana Slicer. As a parent, it is a wonderful device that not only entertains my children, but encourages them to eat their fruit. I don’t have to do a thing!

      @jfowlie:disqus I am probably being a little unkind to the slicer. I can see it might be fun for kids – but do you have trouble getting kids to enjoy bananas? A fun broccoli or carrot cutter might have had more appeal when my kids were younger.

      I stand by my assertion that – regardless of its charm – as an item designed to perform one extremely specific and relatively easy task, it would be avoided by pro chefs. Every chef I know (I know 3 or 4) prides themselves on their knife skills and takes any chance to show them off.

      • jfowlie

        My kids are strange… they love their veggies. They’d eat broccoli and carrots until they turned the colours of the Irish flag.

        I certainly don’t argue your point on chefs, though — and the fundamental point you’re making in your article. Even I pride myself on my limited knife skills. (Every so often, though, it’s fun to just let loose with the banana slicer — when no one is looking, of course!)

    I think it’s pretty amazing. It looks great but…

    A friend of mine told that they own all your pics that you use the filter with for whatever reason they want (and this seems to be verified by the fact that as you say the processing is done on their servers, so you’re pic is on their servers)

    • http://sitepoint.com Alex Walker

      That’s an interesting angle, @peter65j:disqus . I haven’t heard anything about that before but I’d be interested in a link that confirms that idea.

        Well I shouldn’t have said owns your photos because that’s not correct but it is in Prisma’s terms and conditions:

        “Prisma does not claim ownership of any Content that you post on or through the Service. Instead, you hereby grant to Prisma a non-exclusive, fully paid and royalty-free, transferable, sub-licensable, worldwide license to use the Content that you stylize on or through the Service…including but not limited to sections 3 (“Sharing of Your Information”) and 4 (“How We Store Your Information”)”

        So I’m no legal expert but it sounds like they can use ur pix for whatever they want. So don’t be surprised if you see your photo used for an ad somewhere potentially for a product you don’t like.

          Agreed on your interpretation. I believe Instagram had a similar clause in their terms.

          See, I don’t have a big problem with them using my images to promote the service itself. But, if I understand correctly– “on or through the Service”– means legally there’s nothing stopping Prisma from starting a commercial stock imagery service offering our images.

          I doubt that’s their intention, but there’s nothing stopping them and they’ll need a business model at some point.

          I wouldn’t be surprised if they’re just looking to be acquired by Instagram or Facebook.
