Claire,
In addition to what Creative Explorer said, when you crop a photo in PS, you fundamentally replace it by a smaller photo in pixels x pixels only containing the desired part.
"I cropped my photos in Photoshop. ... And even in Photoshop, the quality is poor." seems to show that this smaller image is too smal to work with.
I am afraid the only viable way is to create/find a new photo in a (much) larger size in pixels x pixels (of the part you wish to use); if possible, the obvious way
...
Bonsoir,
Merci pour vos réponses et vous conseils.
Je vais essayer.

@ClaireMylene When you crop a photo in Photoshop, you're working with a raster image, which is made of tiny colored squares called pixels. When you copy that image and paste it into Illustrator, a vector-based program, you're essentially taking a pixel-based image and placing it into a program that uses mathematical lines and points. Illustrator doesn't understand the pixels in the same way, so it treats your photo as a single object.
The quality of your photo depends entirely on the resolution of the original image you started with in Photoshop. The more you crop, the fewer pixels you have, and when you move it into Illustrator, that low-quality image is often stretched or resized, which makes it look blurry or pixelated.
So, how do you fix this? Simple—Link the Image, Don't Paste!
Instead of copying and pasting your image from Photoshop, use the "Place" command in Illustrator. This keeps the original, high-quality image file separate and "link" it to your Illustrator document. It won't try to mess with the pixels or degrade the quality. And any edits you make in Photoshop will automatically update in your Illustrator file. Think of it like a shortcut to your image file—Illustrator is just showing you what's in that file, not trying to absorb it.
Although, if you plan to give the Illustrator file to someone, you need to include the image as well because it is 'linked' — or you can Embed the image when you pass-it over to the person. This will make the file a little larger too.
In Photoshop, save your file as a high-quality format like a .TIFF or .PSD file. Go back to Illustrator and open the document you want to work on. Go to the menu, File > Place... (or press Shift Command P (Mac), or Shift Control P (PC). Navigate to where you saved your image, select it, and click "Place." In the "Place" dialog box, make sure the "Link" box is checked. This is the most important step! When ready, click where you want to place the image in your document.
