Gimp: How to Make a Photo Mosaic Portrait
Gimp: How to Make a Photo Mosaic Portrait

In this Gimp Workshop we are going to create
an amazing photo mosaic portrait. We are going to do this with the standard
options in Gimp, so there are no plug-ins required. You have to organize 25 images in a separate
folder, that you want to use to make the mosaic image. Now we start by going to file, open as layers, and select and open these 25 images. The amount of 25 is important, but they can
be of various size. Go to image in the menu bar and click fit
canvas to layers. Hit Ctrl+Shift+J on your keyboard to fit the
image in the window. Back to file, open and open the image that
you want to use as a portrait. To achieve the same result as in this video, the size should be approximately 1920 by 1280 pixels. Click the thumbnail of the 25 mosaic pictures. Now hit Shift+C to activate the crop tool. Go ahead and check the option current layer
only, and then check fixed aspect ratio. Fill in the ratio 1 : 1. Crop the visible image so we get a square
shaped image. Hit enter or click in the corner to apply. Then we make this layer invisible by clicking
the eye, and we select the layer just below this one. Here again we crop the image and hit enter
to apply. We make this layer also invisible. Now select the next layer, just below this
one. Go ahead and crop this image, hit enter, make
it invisible, and select the layer below it. In this way we continue until we have cropped
the last image, at the bottom of the layers stack. There is no batch option in the standard Gimp
program, so we have to repeat manually these steps for each image. This might look like a lot of work, but it took me for these 25 images, less then 5 minutes. With the bottom layer selected, we hit Alt
+L on our keyboard. Then we hit the S key, so we get the scale
dialog box. We only have to type in 100 and then we hit
Alt+S on our keyboard, so the image is scaled. Hit the upwards pointing arrow on your keyboard, to make the layer just above the previous one active. Hit enter to make this layer visible. Hit Alt +L on your keyboard again. Then we hit the S key. Type in 100 and then hit Alt+S again, so this
image is also scaled. Hit the arrow key to make the layer just above
this one active. And hit enter to make it visible. Repeat the same steps again, that is: Alt+L, S, type in 100, Alt+S, arrow key and enter, and repeat the steps for all the images. In this way we scale all the layers, until we are at the top of the layers stack again. Here too, it only took 4 to 5 minutes to complete this. Then we go to image, and click fit canvas to layers. Now hit Ctrl+Shift+J to maximize the image
in the window. Press Shift+Ctr+N to make a new layer. Rename it mosaic and make its fill type white. Click okay. Go to image, click configure grid. At the spacing we fill in 100 and when we
click the ok button, the width as well as the height are 100. Go to view and click show grid. Back to view and now click snap to grid. Then we go to layer, stack and here we click
on layer to bottom. Hit the M key on your keyboard to make the
move tool active. Now we are going to make a square of 5 by
5 images, and fill this with our 25 images, as shown in the video. When we move the little pictures, they will
snap in its place. You might want to vary the colors and or the
darker and lighter images, while you place them in the square. When you feel its okay, go to image and hit
flatten image. Hit Shift+C on your keyboard to make the crop
tool active again. Crop the square, the selection will snap in
its place. Then hit enter or click in one of the corners
to crop the image. Hit image and click fit canvas to layers. Then click on the zoom icon in the top right
to maximize the mosaic image in the window. Now we go to filters in the menu bar, click
map and then small tiles. We leave the default settings as they are,
and just click okay. Back to filters, map and now we hit tile. Here we unlock the chain and fill in the size
of the image, that we want to use as our mosaic portrait. The width is 1920 and the height is 1280. Make sure that the option create new image
is checked and click okay. Now we drag the mosaic image via the thumbnail
of the girl image into the girl image. Change the mode to overlay. Go to colors, click brightness and contrast, and make the contrast plus 70 or whatever feels good for you. Click the preview off and on and when you
think its okay, click okay. And there we have it, an amazing photo mosaic
portrait. I hope you enjoyed this tutorial, if so please

    I no longer know what to say not to repeat myself continuously, hahahah. Just that you do a great job and your videos are constantly discovering new tools that we use very little in Gimp and that are of great help… What I mean is: thank you so much for your help. Sorry for the mistakes : ^ )

    Hi Jan, it might be a bit monotonous, but to avoid repeating myself (since your tutorial already contains so many repetitions in editing the photos for this photomosaic portrait), I fully concur with the words that Markos wrote to you. As you know, repetition is the power of advertising, so do not be surprised if next time you receive those nice comments again. Provided that the next tutorial is of course more than worth it! ! … hahaha 🙂

    I have no thumbnail of the two different files (the 25 pictures and the portrait picture). They just open in two separate windows. Am I doing something wrong?

    I showed this to my students last school year and they all made great portrait mosaics. However, we updated to the new GIMP 2.10 and you can no longer go to Filters>Map>Small Tiles, because Small Tiles is not there anymore. So how can this be done in GIMP 2.10?
