The human eye sees at about the same FOV feild of view of a 43mm lens as measured on a 35mm camera. This makes sense that on a 35mm camera

a 50mm lens is considered normal. A longer lens flattens the perspective, much as wider lenses widens the perspective.

The point of photographing a product is to place it in such a position or light that allows a purchaser an ability to see all the

positive reasoning behind trading their dollars for its purchase. Its the legal departments job to insert a disclaimer, just in case you find out the

negative aspects or possible uses of that product... Even then, your educated mindset makes for a great business person/client relationship.

A photographer must possess great PR skills as well as artistic flair and ample humility when others (who may be paying the bills) do not.

Knowing which lens works for what product or scene will facilitate satisfatory results every time. Patience in learning these things are of the utmost importance.

Humility, (measured) will allow you to compare notes one session to another. Respect for your client and/or producer keeps your project afloat.

When the money and gift respects one another, there is harmony in the research and development department. There will both get ahead of the competition

and/or adverse condition(s). Zoom lenses allow transition between Wide and Long in one body design, Prime lenses are optically superior,

but computer desogns make that variance very small, small enough to leave the argument for one over the other somewhat behind.

Wide lenses use perspective to make the subject larger, Long or Telephoto lenses compress perspective and makes subjects appear smaller.

Models like to appear small, Packages sell better if they appear larger (value)
