Product Photography - What goes into it

Product photography blog about what goes on 'behind the scenes' and why it costs what it costs
including:
- planning and concept design
- lighting set ups for different items ( reflective and awkward items )
- complexity of different items ( reflective / shapes / heavy items )
- Time involved and needing assistant/s
- Product styling
- Set building
- Group shots of multiple items
- Post production / retouching
we would like the image count between aprox 750 and 1000 words. Quality is more important to us than word count.
We also do not want it to be a sale pitch. Tone should be educational and informative.
