Gary,
Agreed - it looks like a lot of post required from the current images posted, but I think with a little work it will be possible to achieve much better results. Although I'm not sure its realistic to get a portable & completely post-free set up - but I'd bet we can get pretty close!. My examples that I posted are miles away from this - but then they were done with just two speedlights. I've got some more lights turning up this week so should be able to light the thing properly!
Out of interest how many lights do you use in the studio to achieve processing free results?

Three minimal, four optimal....so four

Two in the backdrop.
One in the OCTOBOX, off to the right.
One in a shoot through brolly, left.
The studio is a touch unconventional, and it really shouldn't be working, but it is thank god. It's literally 4 metres x 4 metres, and I have over 3,000 watt's blasting with each shot! There are quirks I am having to work around, but as long as I am fairly strict in the way I work, I am literally taking my images from the camera, straight to the TV for viewing.
What I will say, they are only processing free in terms of suitable for a selection for purchase....they all require editing if bought obviously, there could be dirt on the floor (scuff marks etc), dust / hairs on clothes, the white balance might need tweaking - I might want to change crops etc. The fact is though, when you are getting paid to do it, it's worth it. Before I got my studio working this way, I was spending between 1 and 5 hours per shoot on processing for the viewing. Not good.
I still need to post a full setup guide for the studio, and various examples.
Gary.
