What is Image Resolution?
The amount of pixels in an image is referred to as its resolution. The more detail an image can include, the better the resolution. Regarding Photoshop, there are two ways to increase image resolution: resampling and interpolation.
Resampling involves adding or removing pixels from an image, while interpolation uses complex algorithms to guess at missing pixels. The method you use will depend on the original Image’s quality and what you hope to achieve with the upscaled version.
In general, resampling is better for low-resolution images, while interpolation is better for high-resolution images. If you’re unsure which method to use, try and experiment with both and see which gives you the best results.
Why is it Important?
None can deny that high-resolution images appear so much clearer and simply magnificent. Resolution is essential when printing images because the wrong resolution can result in blurry or pixelated images.
Resolution is also important when choosing an image for a website or social media platform. For example, Facebook recommends images be at least 1200×630 pixels for the best results.
The Difference Between Image Enlargement and Resolution Upscaling
If you’re a photographer, you’re probably familiar with the term “image enlargement.” It is taking a photo and making it more prominent, usually for printing purposes. But you may not know that there’s a big difference between image enlargement and resolution upscaling.
Image enlargement is simply increasing the physical size of an image. On the other hand, resolution upscaling increases the number of pixels in an image, which results in a higher-quality image.
How to Check image Resolution in Photoshop
When working with images in Photoshop, it’s essential to know the resolution of your Image. The resolution is the number of pixels that make up your Image. It’s typically measured in pixels per inch (PPI).
To check the resolution of an image in Photoshop, go to Image> Image Size. The Resolution field is located near the bottom of the dialog box.
How to Enlarge Image in Photoshop
If you’re looking to improve the quality of your images, upscaling them in Photoshop is a great way to do it. Upgrading the resolution will help make your pictures look sharper and more detailed.
When resizing photos, image editing applications such as Adobe Photoshop are perfect. Enlargements can be done in Photoshop, but it is best to keep enlargements to a minimum because quality may be quickly lost.
Enlargements might be made, for example, if a document needed to be printed in a bigger size or the Image needed to have a better resolution (while retaining document size). In this article, we’ll walk you through the steps for doing it.
Step 1 – First, open the Image you want to upgrade in Photoshop. Then, go to the “Image” menu and select “Image Size.”
Step 2 – In the “Image Size” dialog box that appears, make sure to check the “Resample Image” option. Then, select an interpolation method from the drop-down menu. We recommend using either “Bicubic Sharper” or “Bicubic Smoother.”
Step 3 – Once you’ve selected an interpolation method, enter your desired width and height for your Image in the appropriate fields. Finally, click “OK” to confirm your changes.
And that’s all there is to it! After following these steps, your Image should be enlarged with significantly higher quality.
Super Resolution – Adobe Photoshop
Adobe’s Super Resolution tool in Lightroom and Photoshop is an incredible technology that employs artificial intelligence to triple the size of your photographs. If you wish to give your old photographs new life and print photos twice as large with double the number of megapixels in width and height, this is the tool for you.
Here’s an explanation of what it is and how to utilize it. Adobe has developed the Super Resolution feature by training its Sensei artificial intelligence engine on millions of real-world pictures. It compares and evaluates originals to quarter-size reproductions so that the machine can learn the best way to blow them up again.
It behaves similarly to your photos, giving intelligent suggestions on how to improve their resolution. It works effectively on many photos, significantly when widening borders, where it frequently does so without introducing artefacts such as mushiness or jaggy pixelization.
Even faces, frequently the essential portions of photos, turn out nicely. Super Resolution works with Photoshop’s Adobe Camera Raw tool. Adobe trained the function to operate with raw photographs, preferred by photo lovers and professionals for their editing flexibility and image quality. However, Super Resolution can function with standard photographs, such as the JPEGs and HEICs that your phone most likely shoots.
How to Use It?
To use this new feature of Photoshop to your advantage, follow these quick and easy steps:-
Step 1 – Open a raw file to start the Super Resolution process. Raw files would open up automatically in the Adobe Camera Raw tool.
Step 2 – Secondly, right-click the shot and choose Enhance. Command-Shift-D keyboard shortcut on macOS and Control-Shift-D on Windows work just fine.
An Enhanced Preview dialogue box will appear, with a few options for managing the procedure. The Raw Details setting improves the display of raw data.
Step 3 – Check the Super Resolution checkbox to the right of it. Pan around the preview image to see the expected results, click the magnifying glass icon to zoom out and then click back on the patch you want to investigate.
Then, wait until you click the Enhance button. Photoshop estimates how long the procedure will take; it typically takes only a few seconds to convert 12-megapixel photographs to 48-megapixels.
Step 4 – Tap and hold the Option on MacOS or Alt on Windows while you click the Enhance option to sidestep the Enhanced Preview dialogue box.
Step 5 – Then comes the fine tweaking! Zoom in close enough to fine-tune aspects like sharpness, texture, and noise removal by using scales on the tool’s right edge.
Using Super Resolution on JPEG
To use Super Resolution with JPEG, HEIC, or TIFF files, first set Photoshop to open those file formats in Adobe Camera Raw by default. Unfortunately, you can’t just go to the Filter menu and select the Camera Raw Filter menu command.
To begin, browse the File Handling section and select Camera Raw Preferences from the menu. In the following dialogue box that appears, select the File Handling area. Change the JPEG/HEIC option to “Automatically open all supported” images, then repeat the process for TIFF files if required.
Even if you don’t wish to use Super Resolution or the other Adobe Camera Raw editing tools, these photographs will open in Adobe Camera Raw. This is a good option if you do most of your picture processing in Lightroom. However, if you like Photoshop’s default behaviour, turn it off in Photoshop’s options.
DSLRs and mirrorless cameras from Sony, Nikon, Canon, and other camera manufacturers all support raw shooting. Still, smartphones are also improving, thanks to Apple’s ProRaw and Google’s computational raw technologies.
Tips for increasing image resolution
If you’re working with images in Photoshop that need to be increased in resolution, you can do a few things to help ensure the best results. First, ensure the Image is at least 300 DPI (dots per inch). This will ensure that the Image is high enough quality for printing or other uses.
Next, use the “Image Size” dialog box to increase the width and height of the Image. Ensure that the “Resample Image” checkbox is selected, and choose an interpolation method from the drop-down menu. We recommend using “Bicubic Smoother” for the best results.
Once you’ve increased the image size, you may need to adjust the levels and curves to improve the overall appearance. And lastly, don’t forget to save your new, high-resolution Image.

How to use Photoshop to minimize the size of an image?
Lowering the size of a photograph in Photoshop is quite similar to expanding it. If the resolution of an image is too high for the web, the file size is too huge to e-mail, or simply a small image is required for a printed piece, the image size must be reduced.
Step 1 – Open Photoshop and navigate to File > Open. Select a picture.
Step 2 – Navigate to Image > Image Size. A dialogue window titled Image Size will display.
Step 3 – Fill in the blanks with new pixel measurements, document size, or resolution.
Step 4 – Before pressing OK, choose a resampling approach.
Step 5 – To accept the changes, click OK.
What exactly does this mean? Photoshop rejects any superfluous pixels to minimize the image size. By setting a Resampling Method, we instruct Photoshop to modify pixel information to create excellent outcomes when shrinking picture sizes.
Bicubic (ideal for subtle transitions) – An exact approach for calculating the averages of neighbouring pixels.
Bicubic Sharper (finest for reductions) – Based on Bicubic sampling, this filter best reduces pictures while maintaining detail sharpness.
