Q. How do you explain the difference in file size? Your camera is capturing the same number of pixels, so why would the file sizes be different?

A. I think the difference in file size has something to do with the amount of colors, light and shade in the photos. The more detailed photo  takes up slightly more space because of how much information there is being compressed.

Q. How does this influence the way you take photos if your brief requires relatively small file sizes? What sort of backgrounds should you consider if your client needs small files?

A. A fairly plain wall, and taken on a bright, sunlit day to leave a lot less shadowy areas and tone changes.

Q. Assuming you were given a brief such as taking a product shot of a modern " city car " (see left ) that had to go into a web advertisement and you needed to ensure file sizes were small, describe a suitable and a not-so-suitable background you might use.

A. A suitable background would be in front of a greenscreen or a wall, and a less suitable background would be on the street, in front of a highway or busy city location.
