In this tutorial, we’re going to learn how to create a realistic TV effect in Photoshop. We’ll be using some basic Photoshop techniques like layers, masking, and filters. Let’s get started!
First, open up your image in Photoshop. You’ll need to make sure that your image is fairly high resolution – at least 300dpi. Next, create a new layer by clicking on the ‘Create a new layer’ icon at the bottom of the Layers palette.
Now we’re going to add some noise to this new layer. Go to Filter > Noise > Add Noise.
In the Add Noise dialog box, set the Amount to 10% and make sure the Distribution is set to Gaussian and the Monochromatic option is checked. Click OK to add the noise.
Next, we’re going to apply a Gaussian Blur to this noise layer. Go to Filter > Blur > Gaussian Blur. In the Gaussian Blur dialog box, set the Radius to 5 pixels and click OK.
Now we need to add a black and white gradient map to our noise layer. To do this, go to Layer > New Adjustment Layer > Gradient Map. In the Gradient Map dialog box, choose the Black, White preset from the drop-down menu and click OK.
Next, we’re going to invert our gradient map layer by going to Image > Adjustments > Invert. This will give us a black and white negative of our gradient map.
Now we’re going add a Levels adjustment layer by going to Layer > New Adjustment Layer > Levels. In the Levels dialog box, drag the middle input level slider towards the right until it’s at about 1/3 of the way over.
This will increase the contrast of our image and make our blacks darker and our whites brighter. Click OK when you’re done.
Finally, we’re going to add a Curves adjustment layer by going Layer > New Adjustment Layer > Curves. In the Curves dialog box, click on the center of the curve and drag it down slightly.
This will darken our image just a bit and give it more depth.
And there you have it! A realistic TV effect in Photoshop.
