You can make a glass window in Photoshop by following these steps:
1. Start by creating a new document in Photoshop. The size of the document will depend on the size of the glass window you want to create.
2. Next, create a layer for the glass. To do this, click on the “Create a New Layer” icon in the Layers palette.
3. Now, using the Rectangle Tool, draw a rectangle on the new layer. The color of the rectangle doesn’t matter, as we’ll be changing it later.
4. Once you’ve drawn the rectangle, go to Edit > Transform > Warp. This will allow you to warp the shape of the rectangle to create a more realistic glass window effect.
5. To warp the rectangle, simply click and drag on the corners or sides of the shape. Experiment until you’re happy with the results.
6. Once you’re happy with the shape of your glass window, go to Layer > New Adjustment Layer > Levels and create a Levels Adjustment Layer. This will help us adjust the brightness and contrast of the glass later on.
7. Now that we have our Levels Adjustment Layer in place, let’s start adjusting the brightness and contrast of our glass window. To do this, simply move the sliders in the Levels dialog box until you’re happy with the results.
8. The next step is to add a gradient to our glass window. To do this, go to Layer > New Adjustment Layer > Gradient Map and create a Gradient Map Adjustment Layer.
9. Now that we have our Gradient Map Adjustment Layer in place, let’s add a gradient to our glass window.
To do this, simply click on the “Gradient” drop-down menu in the Gradient Editor and choose a gradient that you like. I usually go for a black to white gradient, but feel free to experiment with different gradients until you find one that you like best.
10. The last step is to add some noise to our glass window. To do this, go to Filter > Noise > Add Noise and add some noise to your liking
