Quick Start Video (Must Watch)

This video gives a brief overview of TurboMosaic. The video uses Mac OS X software for demo but it can be used by Windows users as well, because the Windows PC software has similar user interface and functionality.

Recommendations for Main Picture

A picture with complex patterns, very small text, photos with many people, or photos with very little contrast don’t work well as a main picture. On the other hand, face closeup’s, simple logos, photos of large objects, and photos with a lot of color variation work quite well.

Examples of bad main pictures

A picture with multiple people and very small faces.

Examples of good main pictures

Recommendations for Tile Pictures

A large number of tile pictures with a wide range of colors work well because this allows better cell mapping with the main picture.

Cell Style

You can select a Rectangular, Hexagonal, or Circular cell for your mosaic. Here’s a sample close-up photo of mosaics made using these types of cells.

Cell Size When Using Rectangular Cells

Rectangular tile cells can have an aspect ratio of 1 : 1 (Square), 4 : 3, 3 : 4, 3 : 2, 2 : 3, 16 : 9, and 9 : 16. Here’s a sample photo mosaic with 3 : 2 cells:

Pictures that have a different aspect ratio are automatically center cropped for example the following sample photo shows how a picture will be automatically cropped for a 1 : 1 cell.

Number of Tiles

You might like to go for a large number of smaller cells or a small number of bigger cells. You can increase/decrease the number of cells in your mosaic as per your requirement.

In mosaics with Rectangular cells, you can increase/decrease the number of rows and columns. If you’re using Hexagonal or Circular cells, you can straight away increase or decrease the number of cells in your mosaic.

Tile Spacing & Background

Usually, you’d make a mosaic with no spacing between tiles.

But, you can spice up your mosaic by adding a little spacing with a background color or the main picture to show through this space.

Here’s a sample mosaic using Hexagonal tiles and black background color showing through the space between tiles:

Cell Colorization

We try really hard to map the source image with the tile pictures, but our vast experience shows that sometimes it isn’t possible to do this well — this mostly happens when the tile pictures don’t have enough variety in colors for good cell mapping.

For example, if your tile pictures are all dark in color whereas the main picture has predominantly light shades then it would be impossible to map the main picture using those tile pictures. In such scenarios we recommend using cell colorization to better match cell colors. 

Here’s an example of same photo mosaic — the one on left doesn’t use colorization while the one on right uses colorization.

Main Photo Overlay

Using this superimposes the original main picture on the output. We don’t recommend using this option because this is the method usually employed by low quality software/mosaic services that aren’t able to properly map the tile pictures with the main picture.

Using this option results in a “untrue/false” mosaic.

Cell Mirroring

Cell mirroring allows the tile picture to be flipped horizontally. This option can result in better cell mapping because it gives the cell mapping algorithm more picture options. 

For example, given the tile picture on the left, cell mirroring will allow use of both the pictures in the photo mosaic.

Duplicate Spacing

Duplicate spacing is the minimum number of tile cells between cells using the same picture. Cells that use mirrored pictures are also considered as duplicates. 

The first example below shows cells with duplicate spacing 0 and the second example shows cells with duplicate spacing of 3.
