Pixels are the building blocks of digital images. They usually blend seamlessly, but when they don’t there is a visible “pixelation” effect. You can use Adobe Photoshop to pixelate an image on purpose. To understand pixelation, it helps to know how pixels combine to form digital images. Most image files, like JPG, PNG, and GIF, are bitmaps. In other words, they’re maps of bits - essentially grids of pixels that blend seamlessly to form images. Pixelation occurs when pixels become visible to the naked eye instead of being seen as seamlessly blended. Pixelation can happen accidentally - for example, when you resize an image to dimensions too large for its resolution - but you can also create cool effects by intentionally pixelating an image.
One practical way to pixelate is to create a smart filter. Select Filter from the top menu and click Convert for Smart Filters. You can add, remove, adjust, or hide smart filters, so any edits you make are nondestructive. In the top menu, select Filter › Pixelate › Mosaic. The Mosaic filter redraws pixels as blocks of color. If you want to change the pixel size of your photo, move the slider in the preview window to the right to increase it or to the left to decrease it. After you’ve followed steps 1-3 above, click OK. Choose the Eraser tool to remove small sections of pixelation. Use the Eraser on the area you’d like to keep free from the effect. Another way to selectively pixelate is to use the Select Subject tool.
To explore more variations, start by finding your desired Blur effect. From the top menu, click Filter › Blur. Select the type of blur you want and make any adjustments in the pop-up menu. Whether you want to make a photo look like a video game from the 80s, mosaic tilework, or a pointillist painting - or you just want to blur an area to preserve someone’s privacy - you’ll find several ways to do it in Photoshop.

In this Photoshop Effects tutorial, we'll learn how to create a "digital pixel" effect, which is often used in ads that sell anything to do with digital. We're going to first pixelate our entire image using a very simple filter, and then we'll experiment with a layer mask, the opacity setting and some layer blend modes to create different variations on our effect. As I said, we'll be looking at a few different variations on the effect. This tutorial is from our Photo Effects series.
The first thing I need to do for this effect is to duplicate my Background layer. I'm going to duplicate that layer using the keyboard shortcut Ctrl+J (Win) / Command+J (Mac), and now I can see in my Layers palette that I have two layers, with the copy of the Background layer above the original. Next we need to pixelate the new layer, and we can do that by going up to the Filter menu at the top of the screen, choosing Pixelate, and then choosing Mosaic. This brings up the "Mosaic" filter's dialog box. Drag the slider bar at the bottom to change the Cell Size option, which increases or decreases the number and size of pixels that are created from the image. Dragging to the right creates fewer but larger pixels, while dragging to the left gives you more but smaller pixels. The "Mosaic" filter in Photoshop. Click OK to exit out of the dialog box. I'm going to add a layer mask to the pixelated layer at this point. We want black as our Foreground color and white as our Background color. Normally those are Photoshop's default Foreground and Background colors, except when we have a layer mask selected, which we currently do. Whenever we have a layer mask selected, the default colors get swapped, with white becoming the default Foreground color and black becoming the default Background color. To quickly set our Foreground and Background colors to black and white respectively (remembering that we have a layer mask selected), press D on your keyboard to reset them to their defaults, and then press X to swap them.
With the Gradient Tool selected and our Foreground and Background colors set to black and white, look up in the Options Bar at the top of the screen to see which gradient you currently have selected. If it's showing some other gradient, click on the small, down-pointing arrow to the right of the gradient preview area. The Gradient Picker will appear below it. Now that we have our black to white gradient, we can use it to blend the Background layer and the pixelated layer together, creating our first variation on the effect. I want the transition area of my blend to appear across the guy's face, so half of his face (and half of the image as well) is pixelated and the other half is not. The area between where I started and finished my gradient is going to become the transition area between the pixelated image on "Layer 1" and the original image on the Background layer.
Let's look at another variation on our "digital pixel" effect. First, we need to remove the gradient we added to the layer mask a moment ago. We could simply press Ctrl+Z (Win) / Command+Z (Mac) to undo it, but let's re-fill the layer mask with white instead. To do that, with the layer mask thumbnail selected in the Layers palette and white as our current Background color, use the keyboard shortcut Ctrl+Backspace (Win) / Command+Delete (Mac) to fill the layer mask with the Background color (white). Using a soft-edged brush and with black still as our Foreground color, I'm going to reveal the main part of his face by simply painting over it with my Brush Tool. Since I'm painting on the layer mask and not on the image itself, anywhere I paint with black will hide the pixelated layer and reveal the Background layer beneath it. I'm going to let the original image partially show through the pixelated image, and I can do that simply by going up to the Opacity option in the top right corner of the Layers palette and lowering the opacity value. To create even more variations on the effect, experiment with different blend modes for the pixelated layer by going up to the blend mode options in the top left corner of the Layers palette and selecting different ones from the list. First, I'm going to set the Opacity of my pixelated layer back to a full 100%. Just to show you how much different an effect can look simply by changing layer blend modes, we'll try one more. And there we have it! That's our look at how to create a simple "digital pixel" effect and a sample of how we can create different variations on the same effect, and even create entirely new effects, by experimenting with layer masks and blend modes in Photoshop.
Pixelation is those blurry, blocky squares you see when an image’s size is increased too much. Most images are composed of small squares of color information called pixels. As the size of an image increases, so do the pixels it’s made of, blurring the details of the image and creating distracting image distortions. When you upload an image to social media, a blog, or another site, the site often compresses images and photos to reduce the overall file size. Many images are low resolution to begin with. Resize it: Start with a minor resize in the width and height. Resample it: You can select different options in the Resample drop-down menu. Confirm it: Click OK. Enhance it: Right-click your image, and select Enhance. Detail it: Use the preview to make sure the enhancement is working how you want it to be, and then click Enhance.

To eliminate the background surrounding a model in Photoshop, begin by utilizing the Quick Selection Tool to choose the model. Enhance the selection with the 'Select and Mask' feature to smooth the borders and adjust details precisely. The Pen Tool can also be employed for greater accuracy when selecting intricate regions. After choosing the model, reverse the selection to emphasize the background, and subsequently erase or mask it. Adobe Photoshop commands a higher price because of its advanced features for professionals, regular software updates, and its connection to the wider Adobe Creative Cloud ecosystem. It is generally considered the benchmark in image editing, providing tools that serve graphic designers, photographers, video editors, and digital artists. Adobe Photoshop Lightroom is a photo editing and management program designed mainly for photographers. In contrast to Photoshop, which emphasizes intricate photo adjustments and design, Lightroom focuses on non-destructive editing of photos. It enables users to structure, categorize, and apply mass modifications to images-such as brightness, contrast, color balance, and clarity. To begin designing web graphics in Photoshop, concentrate on learning tools such as layers, the selection tool, and layer masks. Start by understanding how to adjust image sizes to web-appropriate dimensions and save them in suitable formats (e.g., PNG for transparent graphics, JPEG for photos). Try designing banners, icons, and various web components. Moreover, get to know Photoshop's guides, grids, and smart objects for accurate designs.
