The first photo is from unsplash.com and I took the second photo on my phone. The unsplash.com photo has better lighting and proper exposure. The cat’s eyes pop and are the focal point of the photo. It has a higher resolution and is more aesthetically pleasing.
The images on the left were taken with a scanner and the images on the right were taken with an iPhone camera. The scanner images have a higher resolution and brighter lighting. They are sharper and look more professional. The difference in lighting stands out the most, so the iPhone camera images could be improved with proper lighting.
