Photoshop’s Generative Fill is an incredible tool, but there’s an issue – the noticeable difference in resolution between the original photo and the generated pixels.
This discrepancy occurs because the Generative Fill generates an image that’s 1024 pixels on the longest side and stretches it across the entire image, resulting in pixelation.
However, there’s a way to solve this problem. Let’s explore the solution through clear and simple steps.
Why Are Photoshop Gen Fill Images Low Res?
Zooming into an area filled by the Generative Fill reveals the resolution disparity.
The fill generates content that is only 1024 pixels on the longest side, which is then stretched across the entire image.
To illustrate, consider a blue square measuring 1024 by 1024 pixels.
When this square is stretched to fit the image, the low resolution becomes evident.
NOTE: Typing HD, 4K, 8K, in the prompt will not work.
Step 1: Increase Canvas Size
To solve the low-resolution problem, we can add extra space to the image piece by piece. Go to Image > Canvas Size.
Here’s the lesser-known trick: you can input equations into Photoshop’s numeric input boxes, including the canvas size box.
Step 2: Add Extra Space
In the canvas size box, input “+1024” (or another desired value) to add 1024 pixels to the desired side of the image.
For a better result, it’s recommended to add a slight overlap, such as 1014 pixels, to avoid visible seams and achieve improved results.
Click on the icon to add the extra space to the left of the image.
You can also check the “Relative” box and input 1014, though it’s not available in all input boxes and lacks division and multiplication functionalities.
Step 3: Generate Selection
Press OK, and the image will now have the additional 1014-pixel-wide space to the left.
Select the Rectangular Marquee tool and choose “Fixed Size” under style.
Set the size to 1024 by 1024 pixels. Click on the top-left corner and Photoshop will generate a 1024 by 1024 selection. Note the 10-pixel overlap, which was accounted for in the previous step.
Step 4: Apply Generative Fill
With the selection in place, click on Generative Fill.
Leave the prompt blank and click on “Generate.”
Photoshop will apply the Generative Fill to the selected area.
Step 5: Repeat the Process
Return to the Rectangular Marquee tool and repeat the process to complete the left side of the image.
By generating the fill piece by piece, you’ll achieve significantly better results compared to generating it over the entire image at once.
Step 6: Apply the Solution Throughout
Continue applying this process to the other side or any additional areas where you want to fix the low-resolution issue.
Remember that this solution is not a bug but a result of Adobe’s testing with lower resolution. Higher resolution results can be expected in future versions.
