The Problem
Developers are wasting time recreating Instagram.
Everyone wants filters. But if you want to add filters to your app today, you have to research image processing libraries,
design filters in Photoshop, attempt to translate them into code and build a filter picker and other controls from scratch.

3. The Solution
Meet FilterKit: Drop in our library...
FilterKit makes adding photo filters to your app as easy as dropping in our library and calling our filter picker.
Unlike existing Open Source libraries, it offers developers a complete toolkit.

The Solution
Meet FilterKit: Drop in our library. We do the rest!
FilterKit makes adding photo filters to your app as easy as dropping in our library and calling our filter picker.
Unlike existing Open Source libraries, it offers developers a complete toolkit.

5. The FilterKit Picker
• Here’s how it works:
• Add the FilterKit library to your app.
• Pass an image from the iOS
camera or photo library to the Filter
Picker View Controller, where users
can browse and apply filters.
• Get back the processed image.
• You can customize FilterKit by:
• Choosing from a thumbnail-style or
our original carousel-style filter
picker (shown here).
• Choosing which filters to offer from
our collection of presets, or find
and share more filters online.

6. The FilterKit Builder
• Designing multi-step filters can
be tedious. Image processing
frameworks like GPUImage let
you adjust parameters one step
at a time, but the best filters
involve multiple steps.
• The FilterKit Builder offers a
visual interface for creating
multi-step filter “recipes.”
• You can visually adjust each
parameter to your liking, then
export your filter recipe as a
new class that can be added to
your app.

7. The FilterKit Gallery
• You can also share your filter
recipes with others by
uploading them to the FilterKit
GitHub repository and adding a
link and thumbnail to the
FilterKit Gallery.
• The FilterKit Gallery makes it
easy to find and share great
filters, so no developer has to
create “that toy camera effect”
again from scratch ever again.
