Koloid Brings the Look and Feel of Wet Plate Collodion Photography to iOS


With the rise of digital photography, good old-fashioned film processing has, for the most part, become a thing of the past for many of us. But with a new app called Koloid, photography enthusiasts can play around with the look and feel of wet plate collodion photography while creating digital images with their iPhones and iOS devices.

How? By emulating the effects one can achieve through the 19th century process. But how does it work?


The user starts the process by taking an image within the application. From that point, the user can tilt their phone to move virtual developing liquid across the composition, thus controlling exposure levels. The longer the virtual developing liquid stays on an area, the darker it becomes (nice touch!).


As put by the developer (no pun intended), “When you feel the picture’s ready, stop the process. Wait a sec for the chemistry to sink in and… voila!”

Certainly, it’s not an actual simulation of the wet plate collodion process, but it’s a cute novelty that promises to produce unique imagery with every use.

Of course, this being an iPhone application, you can bet you have the option to upload the “developed” image to social media. Or if sending by email or SMS is your thing, that option is available as well.

Here are some sample photographs shot using Koloid:





Check it out on the iTunes App Store, where the app is priced at $0.99.

    Why would anyone pay for this?

    Have you ever looked at real 19th century processes? This is not even close… IT might actually be the dumbest “alt pro” app yet…

    Unless you want to put collodion on your computer and dip the computer in silver, there is NO WAY to make wet plate look realistic on the computer. It’s a medium that eludes digital. In hand is the way to appreciate it.

  • Yancey

    Thankfully, doesn’t look like my plates!

  • David Luttmann

    Looks absolutely nothing like a wet plate photo. Hilarious all these apps trying to make digital look like film.

    This is not representative of wet plate photographic processes. The result here is a B&W photo with some added artifacts to emulate badly done or very old or damaged wet plate photos. Wet plate collodion can create superior, sharp photos with almost limitless resolution and these look just like regular B&W’s run through a filter.
