Step 6: Making the Mosaic photo

Open the main image in Photoshop
Add adjusting layer > Pattern
Choose the created mosaic pattern

Change the blending mode to Soft Light
Adjust the layer Opacity to your liking

You can adjust the scale of the mosaic pattern, double-click the pattern and adjust the scale on the pop-up dialog box.
You can refine the final image by adding a curve-adjusting layer

Two versions of the final image are shown below

Step 1: Prepare the Mosaic Images

To create the mosaic, we’re going to need a bunch of photos. How many depends on the size of the mosaic/how you want your effect to look. The main thing is to choose a square number so you can create a pattern with the same number of rows across as it is tall.

For example, choose 49 photos for a 7 x 7 or 100 for a 10 x 10.

Also, if you want your individual images to display as squares, you’ll need to crop the images beforehand. You can do this in Photoshop (check out how to use the crop tool here) but this will be quite time-consuming if you’re working with a lot of photos.

I used the batch features in Lightroom to quickly crop mine. You can also use any photo editor that has these capabilities or you can find a free online tool to do the job.

Now, we need to get all the images into the same project in Photoshop. We could painstakingly do this by spending all day placing each photo. Or we can let Photoshop do the heavy lifting and have it done in a matter of seconds.

Assuming you want to go with the second option, here’s how to do it.

Moving down, let’s set up the grid. In the Units box, you can choose how you would like to measure your images. I’m going to use inches and set the width and height to 2. This will create square boxes for our images. If you want a different aspect ratio, this is where you put it.

Make sure the Flatten All Layers box is not checked. This will put each image on its own layer so you can modify its positioning later if needed. Make sure the Mode is set to RGB Color and the Bit Depth is 8-bit.

Building a Mosaic Image in Photoshop

Photoshop’s layer system was designed for tasks like this. Adjusting the opacity of each layer before applying it to the final image is a must. A transparent image will help you line up the stars at the edges of each panel with each other.

Bring all of your image panels into a single laid photoshop file as layers. You may want to use a reference image of the final framing to use as a base layer at the bottom

You can adjust the opacity of each layer (see below) to 50% to align the stars of each panel up with each other. When all of the layers are properly aligned, you can set each layer back to 100% opacity.

The graphic above shows why capturing a healthy amount of overlap area is important. If there is a gap between image panels, you will need to go back out and photograph the missing areas.

Take advantage of the guidelines tool (View > New Guide Layout) in Photoshop to help align each panel together. In the example above, a full-color, processed image is shown. In reality, this stage should take place before any major processing tasks have taken place.

You may want to perform a simple stretch in PixInsight or Photoshop applied evenly to each panel before aligning the images. A mismatch in processing techniques between panels will result in an odd-looking image.

Step 6: Put on the Finishing Touches

At this point, your mosaic now looks like a mosaic. But you may want to make some adjustments to balance the image and the mosaic better.

There are a few different things you can try. You can lower the opacity of the mosaic layer if it seems too strong.

Or you can add adjustment layers like Brightness/Contrast to adjust the brightness and contrast settings. Try putting this layer between the image and the mosaic layer for the best results. Find these adjustment layers by clicking the half-filled circle icon at the bottom of the layers panel.

Try experimenting with other adjustment layers until you get a look you like. Remember, if you want to affect only the top layer, you’ll need to use a clipping mask.

For my example image, I brought down the vibrance and saturation on the mosaic layer so the bright colors don’t distract too much from the monkey.

And here’s my final image!

Acquiring the Image Panels

To create a successful mosaic image, you must carefully plan your imaging session to collect each panel of your intended image frame. Plate-solving will help with this, and there are several tools in software such as Sequence Generator Pro (SGP), and TheSky to help you with this.

Sequence Generator Pro includes a handy Framing and Mosaic Wizard that allows you to fetch the target area, define the camera scale and pixels, and more. The level of automation possible with this routine is remarkable.

The following video explains how to use the framing and mosaic tool in SGP in detail.

If you’re not using the framing and mosaic tool in Sequence Generator Pro to plan your mosaic projects, you can still apply the same techniques on your own.

When collecting your data, the key is to include an adequate amount of overlap area so that you can safely merge the panels together without creating visible “seams”. Most astrophotographers recommend at least a 10% overlap area to safely merge the images together without the worry of having to photograph a new panel.

Planning the panels of a large astrophotography mosaic.

One of the more challenging aspects of creating an astrophotography mosaic is the ever-changing imaging conditions. Light pollution can be a factor, but also the moon phase . Frames shot during a full moon (even narrowband data) will look washed out compared to new moon data.

It is possible to create a nightscape or deep-sky mosaic using images shot at varying focal lengths, but you will need to perform some careful scaling and alignment in Adobe Photoshop. I prefer to manually align and scale my mosaic images in Photoshop, using a soft feathered edge between panels.
