I was just wondering if anyone knew how to make an image clearer after zooming in. This is because when zooming into an image, the part you zoomed into is all blurred.
Is there any way of making the image that you just zoomed into really clear? As clear as it was before with it zoomed out?
I have tried sharpening it but it makes hardly any difference.
Yeah, with raster images (images made up of pixels), you can't really clean up the quality that much when zooming in. For example here is the Ozzu logo that was a PNG image at 128x128 pixels, and if you zoom in on it you can see that it simply blows up the pixels. There is nothing you can really do to increase the resolution of the image because it's simply a grid with pixels lacking information on what to do to fill in as you zoom in further. So what happens is the image will start to look blocky instead, notice the edges in this image

You need to use vector images (images made up of location points) to be able to really zoom in without losing quality. With vector images since everything is mathematical, you could in theory zoom in forever with perfect quality. Here is an example of how a vector would look as it scales up:
Note: this image is actually just a screenshot of a vector scaled up, but you should get the idea.
It's just really not possible with raster images. You can zoom in and clean up some with sharpening or other tweaks, but that is about all you can do.
I agree you can't zoom in without losing quality, but no one really explained why so let me attempt.
Basically with Adobe Photoshop, or any other image editing program when you send the command to double the dimensions of the image, it takes every pixel and doubles it.
So basically you could have a red-green, green-red square:
RG
GR
And end up with a much larger square but the same pattern:
RRGG
RRGG
GGRR
GGRR
I am sure most programs will actually take the mean color between the two bordering ones to make up the new pixel.
Axe's answer is the best way. If you use vector images you will never lose any quality zooming in or resizing the image to be larger.
However, with that said there isn't really any answer here on how to deal with raster images and if you want to improve the quality of those images after zooming in. There are a few things you can do that might help to make an image clearer after zooming in:
On that last item regarding utilizing AI, Adobe Photoshop has been making quite a bit of updates to integrate AI into their software. For example, under the Filter Menu, you will find a section called Neural Filters which is where all of the AI-based filters are being placed. One of the filters in this section is called Super Zoom which lets you zoom in on an image and enhance its image details. As time goes on these will likely improve, but again could be useful. Here is what that AI Filter looks like:

If I am on the right track here, I and afraid you can't make it clearer. Pictures that are created to be small, or ones that have low quality or a low number of pixels do not have much clarity. As soon as you zoom in you lose all of the detail, you can only really zoom into high-quality pictures.

Are these photos from a digital camera? Or something you've designed?
