Making of the Fruit Tartsby Hau Ming (Jamie) Li, USA
This tutorial is more for people who already know how to set up a skin shader which looks like this.
If not, read this tutorial from lamrug. Also, it would help if you read my Cheese Platter tutorial as well.
For the tray, I used a blinn instead of a mia-material because of the low cost of rendering time. The mia-material requires physically accurate lights like Final Gather and Global Illumination to make it look good and a blinn does not. Depending on the closeness of the camera, a tray with a mia material renders longer than a tray with a blinn. Here is the file I used for the color and reflectivity along with the specular attributes of the tray.

For the doily, the biggest picture I can find on the internet was 500 pixels wide with no alpha channel information. So I scaled it out to 2048 and used the magic wand tool in Photoshop to take out the black background. Then I used brightness and contrast and moved the sliders to fill the missing white color of the doily and it looks good as new. I called that my transparency layer which I saved as a targa 32 file. For the bump and reflected color maps, I filled a blank layer with noise, then motion blurred it, duplicated that layer, rotated it 90 degrees and played around with the layer and opacity in Photoshop to create that cloth-like criss-crossed look. Then I merged those two layers which I put the merged layer on top of the beveled doily so the doily will have a pattern for the bump layer. I saved that as a targa 24 file for my bump map. I used a lambert in the beginning, but for some reason, it kept coming out blurry behind the shadows of the crusts. So I changed to an anisotropic material with little specular. Here is the transparency and bump map.

For the blueberries, I took a piece of the biggest blueberry picture I could find on the internet, and put it all over my UV layout. Then I fixed it up using the clone and healing tool, brightness and contrast, sampled the blue color, filled the top layer with blue and used that as a tint and played around the layer modes. I used a phong with little reflection turned on and used this color map.

For the tart crust, I had the hardest time finding a high resolution image to create my texture. I even thought about taking a picture of it using my digital camera, but my camera doesn’t have the manual controls to take extremely good detail. So while I was searching for an alternative image for my crust, I found this really high resolution picture of biscuits which has a similar texture of a crust. So I took a piece of it, scaled it out, fixed it up with Photoshop, painted a strip of brownish color for the burnt part for the color map. The bump map is just a simple noise texture. I played around with the brightness and contrast to create the specular map with a black background. I also used this map for the reflectivity of the phong to give the crust details. Reflected Color is gray. Here are the maps of the tart crust.

For the blackberries, I used a phong with a procedural fractal shader and played around with the specularity.

The pomegranate seeds had two layers. There is the whitish tip inside the pomegranate seed and a reddish transparent outer skin of the seed. This is the probably the hardest fruit I have ever textured, since I couldn’t find it in the supermarket of my last residency, and most people I know have never seen the actual fruit so they really couldn’t tell what they were on my tarts nor on the photo concept. For the whitish part, I used a surface shader with a small glow. For the outer part, I used a transparent phong.
