The Great Tempera Experiment, Part 2

What are we doing in this project?
• What are the objectives of this project?

The objectives are to capture the value in the facial feature chosen. I myself have chosen the eye. I need to use proportion and value to capture the eye.
• What is your goal for this project?

My goal is to make my eye look similar to the picture. I want to capture all of the value in my eye. I also want my eye to have proper proportions.
• How will you accomplish this goal?

I will try to be very observant of my image. I will try and make it look very real. I have already made my sketch exactly the same size as the eye in the image. I used measurements to do this.
• At what stage are you in this project?

We are at the sketching stage. We have already made the initial sketch of the outline.

II. Take a screen shot of your Photoshop file, and add this to your post.

• Why did you choose to paint this part of your face?

I chose this part of my face because it has a lot of value in the picture. I like how the eye looks also.
• Try to explain as best as you can, what you did. (Taking photo, cropping in Photoshop, guidelines to make the grid…)

First, we changed our image to the right size on photoshop. (5×7) We then used math to figure out what evenly goes into 7×5. We found the measurements and dragged the lines from the ruler to the exact spot. Once we finished that we put our eyes on a google drive folder. We then looked at our image of the eye and drew it on a piece of paper. We first made the exact same grid lines on the paper. I made sure to get every measurement correct. I made sure that all the parts were proportionate.
• How has the grid been helpful in the creation of your sketch?

The grid was very helpful because we could get the exact measurements of where things were. This made it the perfect size and it will be easier to paint it now.

III. Post a photo of your egg tempera experiment from yesterday.

• What pigment did your team use?

Cocoa powder.
• Please explain your process— how did you turn this pigment into paint?

First, we ground up the cocoa powder with a pestle and mortar. We then cracked an egg. Mert ran the egg through his hands to get rid of everything around the egg yolk. We then poked it with a tooth pick. This made the inside of the yolk come out into a container. We then mixed some water in with the egg yolk. We mixed it for a few minutes. We then added the powdered cocoa to the yolk and water mixture. This caused it to turn brown. We then tried different variations. Using more water, less water, more pigment, etc. We made the scale of trials (image above).
• What did you learn about this pigment?

We learned that if we added a little more water to the mixture it had the best result. The pigment is very nice looking and is a good color brown.
• Evaluate the success of this pigment as a potential paint.

The pigment was a good paint. It was not very granular making it easy to paint with. I believe this is a very good paint for something brown.
• Thinking back to your first value scale with the powdered pastels, which pigments (the powdered pastels, or the pigments brought from home) do you think will be more successful paints to use for your piece?

I believe the pigments brought from home will be more successful. The pastels were grounded from a whole stick making it have a lot of clumps. While the things brought from home are mostly already powders. They require some grinding but not nearly as much as pastels. The colors are also a lot better because there are less clumps. Overall I believe the objects brought from home are better to paint with.
