Oliver – Final Project

The Different Rainbows of the Instagram LGBT Rainbow

My project explores the LGBT community by means of social media, Instagram in particular, and employs color mapping to determine which colors are used most often in photos of each facet of LGBT. To gather data, I used IFTTT to save all photos with a particular hashtag to a folder in my Dropbox. For example:

I then wrote code a color-mapping algorithm in Processing, as well as a user interface with six functions. My color-mapping algorithm looks at the HSB color values of each pixel of each photograph. If the saturation and brightness are within certain ranges, the pixel is classified as black, white, or grey. If the hue, saturation and brightness are within certain other ranges, the pixel is classified as brown or as “white people color.” If the pixel does not fall into any of those categories, the algorithm finds the closest hue (out of 8 hues that I chose) and puts the pixel in that category. Then the pixels colors are aggregated within each category, and I calculate what percentage of the total pixels in each category are each color. Screens 1 and 2 visualize the color distributions of each category:

       

Screen 1 shows the color distribution with a large sample size (several thousand photos in each category), and Screen 2 shows the color distribution of only the most recent 50 photos in each category. With the large sample size, we see that most of the categories have nearly identical color distributions, with the transgender category being visibly different.

Screen 3 shows very small versions of the most recent 140 photos in each category. Here we can begin to see why the color distributions differ. Just at first glance, it seems that in the transgender category has more images that have a white background and text in the foreground, and comparatively less photos of people than the other categories.

Screen 4 shows a slideshow of photos from the collection, chosen randomly. Looking into all of the faces is almost haunting. The photos are beautiful, sad, random. Screen 5 shows photos randomly from the collection, with a large image of my color-mapping algorithm applied to the photo and a small image of the original photo.

       

Screen 6 is not functional in this prototype, but would essentially allow users to tag photos with different identity categories (gay, lesbian, etc.), sentiments (happy, sad, etc.), or to identify what is in the photo (person, object, etc.). With this application of crowd-sourcing, tagging data could be collected and then used to classify the photos in more ways than just their original hashtags. The photos would then be searchable in several ways (i.e. “show me pictures of sad bisexual people”).

This project taught me quite a bit about gathering and analyzing social media data, user-interface design, color, and algorithm development, and challenged my programming skills. What it’s still lacking is a well-defined “what’s at stake” claim.
