Even when I change ppi from 72 to 330 the guality is still very bad. I ve never had this kind of problem before. Please help me. 😞

What do you mean by "import a photo to Photoshop"?

Are you opening a file?

Are you placing a file into another file?

What are the pixel dimensions of the image?

Hi, propably I figured out what was wrong. When I click the 'open file' option the quality is great as before. I used to 'drag out' an image to PS from my photo galery and this option doesn't works corretly in this moment, but it doesn't matter because when I click open file evrything is OK. It's kinda complimcated for me to describe cause I'm not native speaker. Now my PS works asa I want. 🙂 Thx

Forget ppi for now - that is just a number stored alongside the image to tell a printer driver what size to print the image on paper - literally how many pixels to use in each inch of paper. It has no relevance on screen other than to set the rulers and to set text sizes when using points.

On screen all that matters is how many pixels make up your image. So that is the question - go to Image > Image Size and read what it says under Image Dimensions i.e. width px x height px. That is the image size you have loaded. What does it say?

When you zoom in with Photoshop further than 100% which is not a physical size but means 1 image pixel mapped onto 1 screen pixel then you will see the image pixels. You are supposed to, after all Photoshop is a pixel image (also known as raster image) editor.

Thanx for your advice. I ve chaenged the width from 1920 to 6994 pixels and height from 1080 to 3934 and the quality is much better. I hope it's the right way to rexolve this problem. But ofcourse I want to have good quality without change the image size every time. I don't know why my PS became to work this way.

You're going about this the wrong way.

You can't just "change" pixels sizes without considering what actually happens to these pixels. Are they upsampled, downsampled, unchanged? Resampling will compromise quality.

If you're working with smart objects - you don't make this clear - then it's even more critical, because smart objects can easily be resampled according to certain rules. Unless you're aware of these rules and what they mean, avoid smart objects.

Upsampling should always be avoided unless as absolutely last resort! Quality will always suffer, and it will never look quite as good as the original left untouched.

When judging image quality and pixel structure, sharpness etc - view at 100% zoom, which represents one image pixel by exactly one physical screen pixel. Zooming in beyond 100 % will be pixelated by definition.
