Faux Half Tone Colored Dot Effect in Illustrator - New or Improved Skill Day 21

I was playing with half tone dots and missed the color and clarity that can be achieved with other techniques and had a eureka moment. I combined two techniques from earlier this month for an interesting effect.

Crop a photo to an image with even numbers, the math will be easier. I cropped my antique diver dude to 8"x 10". Place the image in Illustrator.
 
white circle in a black square


























Move off to the side of the art board and make a square, mine is .1 inches. Make a circle, or any other shape you want, with a .1 inch diameter. Center the circle on the square. Make sure circle and square are both selected. Go to Window > Pathfinder > Minus Front. Now you have a black edge with an empty center. Drag this image into the swatches panel to make a swatch. I also made another swatch where the outside edge is white.

Go back to the original image. Press command j to make a duplicate, I always prefer to start on a duplicate layer and later delete the original layer.

Here's the math portion. Select the newly duplicated image. Go to Object > create object mosaic. Select the number of tiles you want and click OK. My image is 8 x 10 and my swatch is .1 inches. I need 80 x 100 tiles.

Create a new layer. Make a 8 x 10 rectangle. Fill it with the circle/square swatch. The image looks a little odd shrunk down since it was designed for 8 " x 10. The nice thing is, since this is a vector, I can make it as large as I want.

If you want the colors to be more vibrant, bring the image back into Photoshop and bump up the Hue/Saturation.
