Now it’s time for the second of my own images and tests.
The tests of PaperSense project compared the effect of the presentation on screen or printed on paper, with or without people in the pictures, and also how different complexity of the image composition influence how we look at images.
The three pictures that got the most attention were all simpler and cleaner in composition. Hardly a surprise – a clean and clear composition is easier to comprehend.
In my analysis, I usually use image manipulation in Photoshop to create different versions of an original image. Then you can see effects and compare how different details or compositions perform.
In this test, I have presented two versions of an image to 4 different participants (plus myself), two of which are highly trained in images and two less interested in pictures. Three are around 60 years of age, one is only 9 years.
– The original version is already partly manipulated, I have arranged the paragliders to, in my opinion, form a nicer group.
The picture composition opens up to the right, and thus is slightly closed from left side. The picture is falling out to the right and thereby becomes a little unbalanced.
– The manipulated image is mirrored and catches the eye better, giving a calmer composition. Moreover, I have removed some disturbing details on the ground, as well as a bird in the sky. I think this version is better balanced and more peaceful.
According to the eye-tracking test, the manipulated image received 20% more attention in total than the original.
Now, the test group is small, so we can not draw big conclusions from the test. The pictures were shown for 8 seconds and were part of a suite of about 35 images. There were some other pictures in between, so they do not come directly after each other.
– When regarding the total eye-tracking, the effect of the retouch is evident. The picture turns out more concentrated, which is my intention.
– I also show some videos where you can follow the eyes of the various test persons while the looked at the pictures.
The videos reveal two main strategies when looking; focused or general scanning. Furthermore, you can also see that almost all start watching the paragliders, then the ground and then the rest of the image.
The original image; the paragliders though are modified, see below.
Detailed Picture of the paragliders as they were grouped when photographed.
Modified picture, mirrored and some retouch. My choise.
The combined, total eye-tracking, of five people.
The original picture, looking a little more fragmented than the subsequently retouched version.
The modified picture, more concentrated as indicated by the eye-tracking, which is what I intended.
Below is a gallery in which you can flip through the different results.
Further down you will also find video recordings.
At some points, there is a big difference in what the heat-maps show and what the films show. That’s because if you move your eyes very quickly, then the software don’t interpret a fixation and produces a coloured spot. However, one can in detail follow how the eye wandered around in the picture when looking at the video.
All tests are shown in the same order, first the original image, then the modified picture:
Young girl, nine years
Man, around 60 years
