So I decided to post this question to Dr. Mustafa Abushagur who is the Director Microsystems Engineering at RIT. He has been working in the field of optics for 25yrs and is a Fellow of OSA and SPIE. So here is what he had to say about this question:
The aperture size and focal length of the lens plays a role
in the quality of the image to be captured. Camera lenses are usually
identified by their f/number (f/#). The f/# is defined as the ratio of the
focal length to the diameter of the aperture. In single-
I would like to thank Dr. Abushagur for taking the time to answer this question. Some thing I wanted to note about the image he included here on the left is about its depth of field. If you notice some of the flowers are in focus and others are out of focus. This is a great example of depth of field and how in current camera phones it is limited and creates images similar to this. In future posts I will cover more on this topic.
