Today’s post continues our discussion started yesterday about a particular paint synthesizer approach to generating a traditional photo mosaic rectangular grid. Yesterday we discussed how to modify Path Application control panel settings to setup a regular grid tiling that sub nests with no overlap as the maximum brush size is reduced in 50% increments.
This feature allows for additional hand painting with reduced brush sizes to add additional detail to a regular grid photo mosaic, while still staying true to the original regular grid tile positioning. The first image above shows a simple example of what I mean by this. We’ll explore this approach to building a photo mosaic image in this post.
Auto painting was first used at the maximum tile size to automatically generate a photo mosaic image with large tile blocks. The 2nd gallery image at the top of the post shows this initial auto paint photo mosaic. Note that there’s not much edge detail represented in this image due to the large block size used.
I then used 50% and 25% reduced brush sizes to hand paint in some additional detail at appropriate places in the canvas. The size reduced tile blocks automatically position themselves to fit within the larger tile positions with no edge overlap.
You can use the Source Onion Skin feature to present a visual aid to help you with your manual painting. The onion skin is a semi-transparent layer that displays the original source image mixed into the paint canvas. You can turn it on and off using the Canvas : Onion Skin : Toggle Onion Skin menu shown below. Note that there are different kinds of Onion Skins, so you want to make sure the Source option for the onion skin is the active one for this particular example.
