Week 4 (03/02)

Pitchtest
Determining the LPI for the smaller lenticular piece


Process
Firstly, I downloaded the Pitchtest application, and input the values as per the tutorial. We were testing and finding out the exact LPI for the smaller lenticular piece. My friends and I decided to combine our tests for a quicker and wider range of tests, so we each took a bunch of different values testing from 31 to 33 LPI. We had to print these out on glossy papers, actual size. Then we laid these prints out on a table and took turns comparing our smaller sheets by laying the lenticular piece over the tests then seeing which strip appeared the clearest, to determine the actual LPI of the smaller piece. After a series of headache inducing tests, we found the actual value to be 31.64 LPI. This was so gruelling that I was dreading the testing for the bigger piece. Luckily I had friends to combine the tests with to make the process smoother and simpler.  









Week 4 (04/02)

Lenticular Interlacing
Grape



Grape Values
I learned how to use Grape, inputting the dimensions of the lenticular piece under picture width and height. I also inputted the LPI values under measured pitch. For this class, we were testing out the animation for 2 different DPIs - 300dpi and 600pi. For this, I only had to change the first 2 values accordingly. For the screenshot on the left, it was the settings for printing in 600 dpi.



300dpi



Photoshop
I picked 2 random images from Pinterest then placed them on top of each other in Photoshop, in separate layers. I also adjusted the sizing and dimensions according to the dimensions of the smaller lenticular piece, making sure to keep this image 300dpi. Then I exported both the layers separately, placing them in a folder and renaming them according to the number of frames which in this case, is 2. Lastly, by using Grape and inputting the values above, it created the interlaced image for me automatically.




      After Effects
      I created the composition, keeping the number of frames to 9 for the 300dpi animation. I also adjusted the dimensions accordingly. I created a simple animation of a magenta circle going from right to left, then exported the animation by the frames. I placed the exported frames into a folder, naming them from 1-9 according to the sequence. Lastly, through Grape, I inputted the same values, picked these frames, and it created the interlaced image for me automatically.

        I picked 2 random images from Pinterest then placed them on top of each other in Photoshop, in separate layers.

Lastly, by using Grape and inputting the values above, it created the interlaced image for me automatically.




            After Effects
            I created the composition, keeping the number of frames to 18 for the 600dpi animation. I also adjusted the dimensions accordingly. I created a simple animation of a green circle going from top left to bottom right, then exported the animation by the frames. I placed the exported frames into a folder, naming them from 1-18 according to the sequence. Lastly, through Grape, I inputted the same values, picked these frames, and it created the interlaced image for me automatically.



              Final Results & Thoughts



              Reflection/Post Activity Thoughts
              After printing the animations out according to their dpi values, I compared the smoothness and what each is better for. I found that the animation for the 600dpi one was much smoother, and it was harder to see the individual frames especially if the animation is more complicated. It also sort of blurred the different frames together due to how smooth it is, compared to the 300dpi one. I also found that having 2 drastically different images made the animation more obvious (common sense but I’m slow). In this activity, I made the animation and the rotation of the composition wrongly, I should have rotated the images to be vertical to fit the lenticular pieces.
