Hello Gustavo...I was directed to our own site under the computer forum and this address...www.wwiirelics.com/photoresizer/shrinkimage.php
After a little practice, I am learning how to work it and I am pretty happy now.
The photobox is called "Photo Studio in-a-box". I paid $100.00 for it and it included a set of diffuser lights, a big unfolding box that has nylon cloth translucent panels that keeps glare off the subject like a portrait studio would use. An adjustable stand for the camera and I shoot with a 10 second timer to eliminate 'shake' in the pictures. I am not an expert so it's very easy to use. The manufacturer has a website. It is
http://www.americanrecorder.com and I bought model number SIB-100. It's all portable and comes with a nice case like a laptop computer would use and it all fits in there for travel. The set up size is 16"x16"x16".
Very well made.
Mark
