Can any one explain the technical faults of the image??

Hi @Yasir Farooq ,

Jagged edges, chromatic noise and compression noise, underexposed in the shadows and details are lost in the highlights due to overexposure.

I see multiple blown out highlights that are distracting.

In addition to what @Jill_C said: Red: colour noise and compression artefacts. The image is simply full with these defects, so they are not limited to the marked areas.

Blue: blown out areas (in photography, they would be caused by a very powerfull light, causing over exposed areas).

just a suggestion ... you should learn first the basics, then make your artworks .... Jagged edges, also known as aliasing, are the visible stair-like or zigzag patterns that appear along the edges of an image or a graphical object. They occur when the pixels that make up the image are larger or fewer than the pixels of the display or output device, resulting in a mismatch or a loss of detail.

Anti-aliasing smooths out jagged lines by surrounding the jaggies with transparent pixels to simulate the appearance of fractionally-filled pixels. The downside of anti-aliasing is that it reduces contrast – rather than sharp black/white transitions, there are shades of gray – and the resulting image is fuzzy.

How do I remove aliasing from jaggies?

There are software solutions that work by averaging pixel colors along the edges, providing a smooth transition and reducing the jagged effect.

Cheers 😉
