Cheetah Cub - An experiment in Mosaic Art

Yesterday I unveiled my first colored designed Opus Pixellatum Mosaic. 

For the past 18 month, I have been creating patterns for my mosaics and other people's mosaics from a 7 tones grayscale palette.

I have also been researching a way to create patterns from wider palettes.

Cheetah Cub is my first experiment of this type. I designed the model based on the 64 colors of Mosaic Art Supply recycled glass Elementile line.

TA DA ! Cheetah Mosaic just revealed.

Although I still need to cleanup the glue, grout and frame the piece - I will keep posting on this process for I now have a secret weapon to clean up this pesky glue ! - I wanted to give you a peak at the beauty of this dramatic technique.

In this short video I am sharing the moment I flip the mosaic built upside down in reverse method how I spray it to reveal the brightness of the tiles. 

Would you like to create your own mosaic from one of your pictures ? 

I will create the model for you, with a list of references and quantities of tiles 
you'll need to build it.

How to Mosaic Art : Principles of Opus Pixellatum

This a first post of a series dedicated to my Opus Pixellatum Technique © and the many variations it allows. 

join us in our investigation and experimentation of a new mosaic art technique
Investigating Mosaic Art's Opus Pixellatum

This first post describes the original, basic Opus Pixellatum technique as I designed it, and how I came to realize its dramatic potential. I will systematically address the wealth of phenomenal variations allowed by this technique, one at a time, in my next posts on the subject. 

I originally developed Opus Pixellatum in 2015 to be able to quickly realize a set of big mosaics. Cutting the tiles is a very time consuming activity. I had found with Mosaic Art Supply a reliable source of great quality square glass tiles and I wanted to figure out a way to work exclusively with their tiles, without having to cut them.

It took lots of thinking and experiments. I finally came up with a powerful technique that cut by half the time needed to lay a mosaic. 

Basically Opus Pixellatum is a way to do mosaics using a model that pixellizes an original drawing or picture, just like a digital image is pixellized as a great number of cells aligned on horizontal rows and vertical columns. My goal here is not to explain the process that creates a pixellized model from an original graphic document, but to explain how one builds a mosaic from this model. 

From a picture like this one : 

Original eyes picture used to design mosaic self-portrait model
I designed a model after this original picture of Daniel's eyes

I design a model like this : 

Mosaic Art Self Portrait Model of Eyes Opus Pixellatum
Blank model of Daniel's Eyes

The principle is easy : Each number printed on the model corresponds to a color of a grayscale palette. 

Glass mosaic tiles Seven gray shade palette
7 colors - Grayscale.

If one would lay the tiles in the order of the numbers we would have the following progression : 

Black glass tiles laid on mosaic art model.
Black Tiles are laid

Dark Gray glass tiles laid on mosaic art model
Dark Grays are laid, can you guess ?

three colors laid eyes self-portrait mosaic art image appearing
2 nuances of Gray, now you surely see it...

four colors glass moaic tiles make distinct image
4 colors : Black and 3 Grays, there we are.

five colors glass mosaic tiles laid eyes selfportrait detailed image
5 colors laid.

complete mosaic art eyes self-portrait black white seven shades gray
A perfect 7 colors image.

Practically, you lay all colors at the same time and in order to keep a small grouting gap between the tiles  it is better to first mount every other tiles. 

Laying every other tiles allows more precise positionning

When I first started to use Opus Pixellatum, I was pleased of how fast it was to build a really good looking mosaic. One day I decided to wait until I had fully completed laying half the tiles before I’d start laying the next other ones. And here is what I saw...

Half the tiles are laid on this portrait of a Yezidi refugee.

On this portrait of a young Yezidi refugee only half the tiles had been laid.... Our brains can intuit what the whole picture is... That is flabbergasting  !

I found the key to some really cool mosaic art !

I did not know yet where I was going with that, but I sure intended to seriously investigate this unexpected occurrence !

Here are what Daniel's eyes would look like with half the tiles laid : 

I'll design a custom mosaic pattern of your eyes in Opus Pixellatum
Only half the tiles have been laid on this mosaic portrait

Key to the unlocking of Opus Pixellatum's potential is not so much the fact that it works with half the tiles laid, but that it does with half the tiles NOT laid, and that their spots can be used for something else !

The next posts of this Opus Pixellatum series will explore this. I will systematically explore the subject and will expose each variation in a dedicated post.  

In the meantime, enjoy Daniel's and his mosaic's smiles !

i will design a custom mosaic portrait of your loved one for you to build it.

3 ways to improve your Mosaic Art Models

In March 2017, during our first Mosaic Art Fiesta I introduced Opus Pixellatum to a group of confirmed mosaic artists. They had traveled from all over the USA to the Mosaic Art Supply warehouse in Decatur, Georgia.

In Opus Pixellatum you build your Mosaic exclusively with square tiles of the same dimensions. There is no cutting. The tiles are arranged on pattern of rows and columns in the same manner as the pixels of a digital photography. 

We create custom mosaic models from your picture.

2 weeks ahead of the seminar the participants had sent me pictures of their faces and I created a model so they could build a mosaic portrait of their eyes during the seminar.

An Opus Pixellatum model looks like a spreadsheet. Each cell bears a number corresponding to a color of a tile to be glued on that spot. Although this sounds a lot like “Mosaic by Number”,  I came to realize through my experimentation with this method during the past 18 month that Opus Pixellatum allows for many dramatic variations.

You can create a mosaic portrait of your eyes, we create the model for you.

With Opus Pixellatum the Mosaic artist can unleash her creativity in ways a more classical Opus Tesselatum approach does not allow. This will be the object of future posts.

While I was generating the models, I realized that the quality of the original picture has a great influence on the final result.

For this seminar, we were working with a grayscale palette composed of 7 nuances : Black, White, and 5 nuances of Gray.

I have realized many mosaics with this very accurate palette.

So you want your well balanced original to actually display a wide array of grayscale. If the contrast is too high, you might end up with only 2 or 3 nuances of gray. This is acceptable on a smaller mosaic but a bigger piece will look much better with the 5 nuances of gray.

When you create your model, the first operation is to turn the picture from Color to Black and White. Often named “Desaturation” this operation can be performed in many different ways, with different results as you can see here.

Quality of original picture conditions the aesthetic of your custom mosaic model
Original photography & 3 types of desaturation.

A black and white picture cannot be desaturated because it already is. You can alter it in different ways, but you wont have the same array of choices you have when you desaturate yourself. 

Advice # 1 : Start from a color picture.

In order to show all the nuances of your grayscale palette in a balanced way, your original picture should not be too contrasted. It is very easy to boost the contrast of a picture but it is more difficult to decrease it without losing accuracy of the features.

Advice # 2 : Shoot your picture outdoors when the sun is low on the horizon (morning or evening).  An overcast day is perfect. Alternatively, ask a professional photographer to do this for you in a studio.

Format :
The best format to create a model is PNG. Most cameras shoot JPG (or JPEG) pictures. JPG files do not take much storage space but every time you modify a JPG picture, you lose some of its quality. So before you work on the picture first save it as a PNG file. Alternatively if you send me a picture to create a model, please send me the original picture – even a JPG - without editing it.

Advice #3 : Use PNG files

Basically, to get the best possible quality for your model :
  • Shoot your picture outdoor in the morning, evening or with an overcast sky.
  • Send me your original color picture without cropping or editing it. 
  • Send it as a PNG file

From your colored photography we design a custom mosaic model you.

Mosaic sometimes can be intimidating. Opus Pixellatum is the easy door into this wonderful world. It allows beginners to build beautiful first mosaics from the beginning, and confirmed artist to unleash their creativity in amazing ways. If you would like to build a mosaic from your own picture, I'll build for you a kit including a model and the quantities and references of the tiles to order from Mosaic Art Supply in Atlanta, GA.

2017 Spring Mosaic Art Fiesta

The First Mosaic Fiesta was held last March 24, 25 and 26 in Decatur, GA.

The event co-hosted by Joe Moorman and Frederic Lecut, from Mosaic Art Supply and MosaicBlues was attended by confirmed mosaicists from all over the USA.

We all met Friday night in a local restaurant.

And got started Saturday at 10:00 AM.

The goal of the event was to introduce my Opus Pixellatum technique to a group of confirmed mosaicists.

Each participant had send me a picture of their eyes or face 2 weeks ahead of the event and I had prepared a model of their eyes. They would realize an actual mosaic of those eyes during the week end.

I had also brought with me all supplies and tools necessary for the work : Grout, Glues, Tweezers, Mounted Backing boards...

The tiles were available from Mosaic Art Supply.

I had previously organized many workshops, community projects and classes so people would discover mosaics. It is a much different feeling to be working with people who have for some of them many years of experience in the trade. They are interested in the matters, and their questions are always pertinent !

Everyone had an idea about the principle of Opus Pixellatum. My goal was to get them to practice, and get a first taste of the many wonderful variations allowed by this dramatic technique. 

Everyone got to work

By laying every other tile... Which allows for a much easier, more accurate laying.

Amy Galbavy has laid about 25 % of her tiles.

And later allows the mosaicist to unleash her creativity in many directions...

Once laid half the tiles in grayscale, you realize you already can see the portrait you have been building. So you now can fill up the remaining holes with any color you'd like to use. No matter what you do, the original pattern is already there. 

As we were building eyes portraits, I suggested to use irridescent tiles to highlight the irises of the eyes...

Sunday morning, we grouted our pieces.

While the grout was setting I explained how to create an Opus Pixellatum model from a picture. I answered many questions, and finally proposed to build models for those of them who would like me to do so. The offer was appreciated.

Stunning Giant Mosaics unearthed in Uzes, France.

In Southern France Gard, the archaeologists of INRAP bring out the mysterious antic town of Uzès.


Since October 2016 over 4,000 square meters have been methodically dug in the highs of the city of Uzes.

The excavations in front of the old Gendarmerie barracks

Nothing was known of the antic Uzès except its name of Ucetia, and that it was the starting point of the aqueduct leading the water from the fountain of Eure to Nimes, through the Pont du Gard. 

Initially the archaeologists didn't think it was a major discovery. But the great quality of the vestiges they found testify of the importance of this Roman settlement.

Two magnificent mosaics

In front of the barracks of the Gendarmerie, where once was the vegetable garden of the gendarmes, a row of rooms was cleared, one of which, 60 square meters, has its floor covered with two magnificent mosaics, older than the ones discovered in Nimes. 

In the center of a succession of geometric borders a sun like image is surrounded by 5 crowns, themselves framed by four animals: an eagle, a fawn, an owl and... a duck.

The Eagle

The fawn. Note the gorgeous Svastiska border.

Minerva's owl ?

A radiant pattern adorns the medallion of the second mosaic, ornated of a red bordered cartouche at first sight empty. In reality, a name is written in white tesserae on a white background. Who is this Loukios Koinilos? A Lucius Cornilius? Was he the owner of the place, the mosaicist himself, or a patron who'd helped finance the building? 

It is not know yet if the building was a domus - a private villa owned by an important man of the city, or rather a public edifice as the dimensions of the hall and traces of colonnade suggest.
What was the symbolism of the mosaics ? Some animals might be attached to deities. The eagle to Jupiter, the doe to Diane, the owl to Minerva. But a Duck...

The Duck ???

Excavations will continue until August. Hopefully more beauties will be unveiled.

Don't you love this border ?
