Canvas

 


This work was designed in Adobe Dreamweaver using HTML Canvas to create digital art out of code. For this design , you can see that the cat is made from several shapes and curves. There are even more shapes that are hidden to fill certain gaps that showed up throughout my project.


I started this project with something more complicated and decided to create something more simple after seeing other student projects. Over the course of creating my image, I came to a point where I had to stop coding and come back later because I was having a difficult time lining up my points correctly. I learned that editing in Adobe Dreamweaver is a very long, complicated, process that takes lots of time and patience. 


The design itself is very personal to me because I got the inspiration to create this image from my pet cat. The title is named after her and I’ve attached a picture below of her for comparison.


 Overall, I am very happy with my image and how it came out. Symmetry is what I aimed for when creating the cat and I believe that I succeeded with making the image even. I hope to revisit this project in the future so I can add some shading and mess with the gradients.

Tag Brush

Image
  My tag brush was created in Adobe Photoshop. For my tag brush, I applied they spray2 overlay and a scratch filter to create the brush. In the brush, you can clearly see my logo in a grayscale format but I am able to change the color by editing the brush. I will be using this tag brush for future projects to copyright them as mine. This project was pretty easy for me. I never created a brush in Adobe Photoshop but by following the instructions on the pdf, I was able to complete this brush in less than 10 minutes. The process was quick and simple!

      For this project, I had to photoshop myself into a scene of movie. I chose Home Alone and picked the scene where Kevin ask for help from Donald Trump. I added myself into the frame to make it look like I'm trying to help him by keeping him away from him.  This project involved masking, working with adjustment layers and acting out an image to execute the photoshop. I took the image of me at work, and had my coworker act out as the boy so I could cut out my body and hand to add to the movie scene. After adding myself in, I adjusted the Hue/Saturation to make my skin tone match.  I found this project to be easy and fun. It took me under an hour to create my scene. Below you can find my original images.

I believe that this image would be hard to photoshop myself in because of  the light beams and city lights that look like they would be hard to match with. Plus there is an illusion of speed going on that I believe I would mess up. This gives me an idea that I want to make a project from a movie scene and flip it around to make it funny. There are many parodies created but this one seems to be the best. The irony in this photo is that Trump is photoshopped as Godzilla and is destroying the county.  This image made me laugh because the editor added in an actually ass instead of photoshopping the girls butt. He wasn't wrong though and technically did what she told.  I found this illusion to be cool because it gives the idea of a couple being together in photo frames. There is so much you can do with this idea with adjustment layers and if I were to do it, I would edit the color and create a different setting in each frame.
