Digital Display

Turn an image into a high-tech digital art. From a distance, it will look like a LED display image but viewing up close will reveal the tiny details.

Note: Make sure that the image is in RGB color mode. To switch to RGB color mode, click on RGB Color under the Image> Mode menu.

Step 1

Open an image you would like to edit. Or, you may use the image used in this tutorial (from iStockPhoto). Using a low-resolution image is fine.

Step 2

If you’re using a low resolution image, use the Image Size tool to increase the dimensions. We recommend at least 2000 pixels wide and tall for better clarity in the final result.

Tip: Ensure that the “Resample Image” checkbox is checked to allow scaling the actual pixel dimensions.

Add a new Hue/Saturation adjustment layer (Layer> New Adjustment Layer> Hue/Saturation). For this step, I will use these settings:

  • Hue: 100
  • Saturation: 100

Tip: This step is optional and may be skipped if you do not want to colorize the image.
