Different cameras can produce different qualities of work, for example a phone camera will have a lot less quality than a DSLR camera. Also, the same can be said for different DSLRs.

Below is my own example of this difference in quality, both images feature the same shot of a plant against an orange backdrop:

This image was taken using a Nikon D300s DSLR camera. the quality of the image is high, this includes the depth and focus in the image. Also, the colours in the photo are vibrant which adds emphasis to the quality provided by this camera.

Contrasting to the above image, this photo (shown below) was taken using the camera on an iPhone 7. The difference in quality is obvious as the image itself appears as if it was taken through a thin cloth, and the colours are almost muted and dull when compared to the other image.
