You can also get creative with the rotation angle and scale, and you can do that by increasing the horizontal scale percentage to a low value, like 100.07% along with the rotation angle and the anchor point,Īnd then use “step and repeat” again, and you will get some unique and amazing results. That’s how we can easily create star trails with one image in Photoshop. Then you can use the mid-tones slider to hide some of the stars in the background, In this case, I only want to hide the stars at the bottom, So I’m going to invert the layer mask by clicking on ctrl/cmd + i, and then I can use the brush tool with 50% flow and capacity and only paint on that area.Īnd that’s pretty much it. You can also increase the contrast of the Star trails layer to reduce the visibility of some of these stars by creating a new levels adjustment layer on top of the star trails layer, and then create the clipping mask by clicking on Ctrl + alt + G ![]() 4 – Add Contrast To Control The Visibility of The Star Trails Once you’ve done that, make sure to change the output mode to “new layer with layer mask”, and then click ok.Īnd now all you need to do is to drag that layer to the top, and then turn on the visibility of the star trails and the background layers. ![]() And you can also change the view mode to overlay and then use the fine as brush tool to paint on the edges and refine the layer mask. You can also refine your selection by clicking on the select and mask button, then take the refine edge brush tool, and you can use the opacity slider to reduce the visibility of the foreground. So turn off the visibility of the star trails layer for the moment, then select the background layer, and then use the quick selection tool to select all of those trees in the foreground, 3 – Restore The ForegroundĪnd now the last thing that we need to do is to bring back the trees in the foreground. Once you have created all of the copies, select the group, and then click on ctrl/Cmd + E to merge all of those copies into one layer, and then you can change the blending mode back to lighten. Make sure to add enough of these, to your liking, to achieve the results that you want.Īlso, keep in mind that making a lot of these copies will increase your file size and Photoshop may crash, So make sure that your system is capable of doing this, And the image resolution is not very high. Now, all we need to do is to tell Photoshop to repeat the last step by clicking on ctrl + alt + shift + T or cmd + option + shift + T multiple times,Īs you start doing that, you will notice that the start trail effect will start to form. Once you have entered the rotation degree, click on the checkbox to accept the changes, and now all of the changes that you just did in the free transform will be recorded in step and repeat. Then you’re going to click on this box to set your rotation degree, and then add the very low value, in my case, i added 0.05 degrees to rotate my image clockwise.Īnd make sure to input the low value so that the stars don’t get spaced out from each other and the effect does not look great. Then you have the anchor point in the middle and you can move this anchor point to specify the rotation point and this case I’m going to change my rotation point to the top left corner. So how this feature works is you’re going to click on ctrl + alt + T or cmd + optn + T to get to free transform and enable “step and repeat”. To achieve this effect, we’re going to be using the “step and repeat” feature in Photoshop to make multiple copies of this layer and rotate them at the same time. ![]() 2 – use “Step and Repeat” to Make Star Trails in Photoshop Now click on ctrl/cmd + G to group that layer. This blending mode will only show the brightest pixels in the image, Therefore only the stars will be visible in the duplicate layer, if the sky of your image is a little bit brighter and some of it is showing you can add the levels adjustment layer and make the sky darker and the stars lighter. Then you’re going to change the blending mode of that copied layer To lighten. ![]() Once you have imported the image in Photoshop, start by duplicating the image layer by clicking or ctrl/cmd + J, or you can drag it to the new layers icon.
