Dear Forum Members,
I would like to create a mosaic picture, similar to the attached one. I have been trying to do this for one month, but without success. I watched all the tutorials, I read articles on the forum, but still do not know how to do it. Is there anybody, who could write me or show me step by step what to do?
I tried many approach and different setups, but the end result is almost the same in every case. The whole canvas is covered with the tiles and the background is not separated from the person on the picture. I tried to change the settings but the canvas is similar: whether all tiles are vivid and sharp, or all tiles are pale/transparent. However, what I want is sharp, vivid images in the background, and pale/transparent images on the person, to be able to recognize the person on the picture.
Can somebody help me please?
Thank you,
Orsi

The example you posted is by long time Studio Artist user Charis Tsevis. He works with movie brushes and paint synthesizer tiling presets to buildup his mosaic images.
Movie brushes pre-date the image folder brush feature in V5. So anything you could do with a movie brush you can also do with an image folder brush. Here's a tip on making photo mosaic images using a movie brush.
Here's some information on how to duplicate Tsevis's mosaic stylings. In particular, this post discusses an approach to duplicate his nested sub-tiling designs.
V5 offers a number of new path start generators that are for use with path start regionization presets. they include some new ones that emulate the nested sub-tiling look that Tsevis pioneered. The mechanics of building path start regionization presets in the paint synthesizer is very different than building presets that paint a single brush nib in a tiling pattern. Path Start Regionization work by intelligently analyzing the source image, breaking it up into a series of different regions, and then filling in the regions one by one.
So the regions are used to generate on the fly brush nibs. A movie brush or image brush will automatically be interpolated to fill in the one time region based brush paint nib.
Path Start Regionization paint presets are using the region fill as brush pen mode. Presets that tile with a single source brush nib are using the interactive pen mode. They work very differently, as we just discussed.
Here's a tip on the different studio artist pen modes.
Here's a tip on creating photo mosaics using path start regionization. Note that V5 has many more associated path start generators since this tip was created using V4. V5 is a superset of V4, everything you can do in V4 you can also do in V5.
Many of the V5 photo mosaic presets in the factory presets we include with Stdio Artist are using path start regionization internally.
So i just pointed you at a ton of very useful information. If after reading it you still have no idea what to do, it would help if you tell us what you specifically don't understand in the tutorials.
You talk about separating the foreground from the background. That is really a function of how you the artist select a particular source image and the set of sub images you want to use to represent it for the mosaic. You need to have enough color variation in your set of sub images to adequately represent all areas of the source image.
You also need a segmentation algorithm (the path start regionizer) that adequately reproduces the detail you are interested in in your source image in the set of associated regions it generates to represent the source image. Each path start regionizer has a set of adjustable controls that allow for introducing more detail into the generated regions, or less detail for more abstraction.
Balancing out detail and abstraction is going to be a tradeoff. one you as the artist need to make.
To a certain extent that is also going to be a function of the size of your working canvas.
There are colorization options you can build into your photo mosaic paint preset that can help in reproducing source coloring by algorithmically colorizing each sub tile as it is being laid down.
Hello!
I prepared the attached picture and my problem is that the tiles in the background are pale.
Can anybody please help how can I make them more strong, more vivid, more colourful
(like the original)? But without changing anything in the foreground (on the person).

Is the background of the source image you are working with pale?
NO!!!!!! Its perfect as you can see in the attached file

I'm having a hard time seeing how either of the 2 jpg files you attached here could be the source for the mosaic you attached (1.jpg).
As an aside, you can embed images directly into the body of your post using the 'image' icon at the top of the text entry widget. 2nd from left icon at top (next to the link one). Makes it easier to read the post since the image displays embedded in the text.
I am sorry, I misunderstood.
So, the background of the source image is a light blue sky with a few white clouds. The 2 jpg files I attached in the previous comment are (2 of ) the vivid and sharp pictures the program puts into the mosaic image as tiles, and I expected them to be the same vivid and sharp in the (light blue / white) background.
I don't know which particular paint preset you are using. Or if it's something custom you made. The reason why i wanted to look at the source image you used is so we could then see how that paint preset is trying to represent the source image. My guess is that there is some kind of color adjustment to the image folder brush going on as a part of the paint preset. So then the paint synthesizer is trying to adjust the coloring of the individual mosaic blocks to better represent the source image.
Based on your description of the source image, it sounds like that is what is going on. So that is why the background mosaic images look the way they do.
Does that make sense to you. Or are you still confused?
You could edit the paint preset you are working with to use the rgb match frame indexing modulator. And get rid of any brush image color adjustment. then the mosaic image blocks will be laid down with no on the fly adjustment to how they look. Just the original image laid down.
What factory paint preset are you working with? Or attach it if it's a custom one. I can better comment on what is going on if i know that.
