Activity 1: Image editing software basics

For the first meeting, we discussed the syllabus, class rules and what the course will be all about. For a three hour major class, I was expecting an activity to be done, but I was not expecting that it will be about image editing. And I was not expecting it will be fun.

I am not sure if it is required to make a post about this activity, as my partner, Gio, said it isn’t. Nonetheless I’ll still put some effort in keeping this somewhere I can reliably check out. Both for the sake of recording, and for the LOLs.

The activity is about familiarizing yourself with an image editing software. We were encouraged to use either GIMP, Photoshop or ImageJ. Or Scilab, but I am still unfamiliar with it so that is out of the question. It is a good thing that the Photonics class the day before also needed the use of such software for testing the pinhole camera model, so I already had GIMP fresh in my Downloads folder.

The activity is simple. Use image editing to put your face on an actual movie poster. Use ratio and proportion make it more realistic.

Gio and I veered away from the movie poster requirement and instead, decided to use this poster.

Wrestlemania 28 poster featuring John Cena versus The Rock in the Main event. Retrieved from I still don’t know why we used this, but I suspect nostalgia.

And so we took our proud poses to capture the replacement faces.

Do you smell what the Ralph is cookin’?! Our shirt colors matching the corresponding flames are purely coincidental.

We used GIMP 2, and I have to be honest, we really sucked at it. I mean, gawd, I will admire my younger sister more for being so good at Photoshop. We were basically grasping in the dark with all these new tools that never existed in Microsoft Paint (a few years back then it was all that sufficed, okay…)

We flipped my image, and proceeded to figure out how to cut off a contour selection. We eventually settled for the scissors tool. The next task was resizing and rotating the image, which were easily done using the rotate and scale tools. Keeping the head to head and head to body ratio in check was a pain, as John Cena and The Rock had different head shapes, and their necks are wider and more muscular than ours. However, we figured out how to separate the image into layers, and we just erased the excess chins and foreheads under the overlaid faces. The result by, graphic designer standards, are fails. But by Odin’s beard, they are majestic fails.

As can be seen, we haven’t figured out how to add glisten and shine to our skin, and the skin color difference is hard to fix. I had to add five layers of darkening on my face, but it will need more than that to get the right tone. Not to mention, my neck is a discontinuity to The Rock’s glorious tattoos.

The presentation proper was so fun. It was full of laughter and embarrassment. After seeing how others fared, I’d say we weren’t the worst (seriously, ours were actually good) but we definitely weren’t the worst. Not following the Rubrik here, I’d give ourselves an 8 because we were not able to choose the right cuts, editing and test image. The final result did not blend well with our faces, and we did not play with more editing tools to further improve the quality of the last image.

Congratulations to Julia and her partner for their exemplary work and presentation mode, using the poster for 22 Jump Street.

As for the others, we can get better at this guys ( I’m looking at you Martin and Jesli).
