Here is an image I did using Cyclorama

I personally thing the results are worth it.

However if you buy the cyclorama from Daz and don't like the results, you can get a refund within 30 days of purchasing it.

I think I used Infinity Cove for this one:

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
