In Photoshop, select the file to open, browse to find the image you want to edit, and click OK.
Use the shortcut Ctrl+J or choose Layer > Duplicate Layer to create a new layer for the background. You should now have a new layer showing up in the Layers panel. Double-click on the text portion of this new layer to edit the layer name and rename it to Starlight Soften.
To add a mask to the Starlight Softening layer, click Add Mask in the layer template or choose Layer > Layer Mask > Reveal All. You should now see a white thumbnail next to the layer mask.
After changing the layer name, the mask will be deselected. Before proceeding to the next step, activate the mask by clicking on its thumbnail in the layer template. A white box around the thumbnail indicates that the mask is selected. Then go to Image>Use Image on the selected mask. Select the default settings for the image tool when using it and click OK. The mask should now show what the copy of the image looks like.
In the layer template, change the merging method of the starlight softening layer to screen mode.
First make sure the starlight softening layer is selected, use the shortcut key Ctrl+G, or select Layer > Create New Group. The new layer group will organize all the layers together. Double-click the layer group name and rename it Starlight Soften. Now, reselect the starlight softening layer and copy the current layer using the shortcut Ctrl+J, or choose Layer > Duplicate Layer.
Select any of the starlight softening layers and choose Filter > Blur > Motion Blur. Set the angle to -45° and choose the distance based on how long you want the stripes to be. If you are working with a high-resolution image and the distance setting you choose does not produce long enough stripes, choose the highest setting and click OK. Then use the shortcut Ctrl+F to apply the filter effect repeatedly until you get the length you want.
