Negative to Positive or how I am trying to move some of my old negatives to digital

First off this is by no means an exact science at this early stage.  As I am still really gathering information and working to try and put this together as best one can without purchasing a lot of gear.  That said I am not opposed to using some funds to purchase some gear.

So let us start with the basics here.

I am setup with the following gear.

Nikon D600
Lester A Dine 105mm macro lens ( f mount) - for those of you wondering these are similar if not the same as the kiron lenses.  They were used by dental offices to do photos of teeth prior to digital.  They are wonderful for macros and I would suggest an excellent lens.  You used to be able to find them cheap on eBay and such but since people have found them the prices are going up a bit.  That said they are great alternatives to Nikon branded lenses.  Fully manual by the way.
Nikon Mount bellows (improving the 1:1of the image I think)
Nikon SB 700 flash
Younguo 622 flash triggers
Light box
flash light
Nikon remote for shutter (no hands on the camera during the shot)
Some paper made into a roll for the flash
Paper cut and taped to the front of the light box for holding the negative

Camera settings thus far:

Manual mode
1/200 of sec on the shutter
ISO 100
f2.8
Flash setup at 0.0 ev

Here is the Nikon with the bellows and trigger for the flash.  Note I have been focusing with the bellows and lens to test out the results.  Thus far the lens is easier to work with in this configuration.

This is the light box and flash.  Normally I have the flash positioned behind the light box with the tube (white paper rolled up and taped) up against the back of the light box.  I then slide a negative into the green paper on the front of the light box and position it into place.  

At this point the setup is really about taking a photo.  I use Live view on the nikon to zoom in on the negative and then attempt to focus the image.  Using the flash light (see the list of things I have above in the setup) I illuminate the negative so I can see it on the live view screen.  Now once I have the focus setup.  I shut off the flash light and use the remote and trigger the shutter.

After this it is time to take the image into photo shop and start working the magic.  Below is an image that I have converted from a negative.  Note there is still a bunch of steps to go to get things looking good.  Stay tuned for part 2 of this adventure.
