Here is my first very fast PDF on how to find your nodal point. Remember all lenses and all focal lengths will have a different nodal point. I permanently mark off my most popular lenses and focal points so I do not have find the nodal point each time.
This PDF will be replaced by a video tutorial this month as well. Any questions please do not hesitate to ask.

Lens alignment night.
Last night I went over to Jerry and Sasha Kobalenko's house to do lens alinment on my lenses. Jerry is a incredible photographer and Arctic explorer please check out his site http://www.jerrykobalenko.com/
Thomas Kitchin http://www.kitchinhurst.com/ along with his wife Vicky Hurst are amazing wild life photographer sent out the Lensalign Pro http://www.lensalign.com/
The Lensalign Pro was very easy to use and set up. Not only will you be able to calibrate your lens but also as Jerry pointed out you learn a lot about your lens as well.
My Sigma that i was never very happy with could not come close to good focus wide open at 2.8. My Tokina 11-16mm again 2.8 was awful. I would never use this lens at that aperture but at F8 it was great and that is where I start to use it anyways. My Nikon 105 2.8 macro was back focused and with some on camera (D300) ajustments we got it to where we wanted.
Would anyone like to buy a Sigma 28-70 F2.8?

I am building my new website at the moments and am currently using the following programs and code to build it:
http://www.medialab.com/sitegrinder/
I have been using this program now for 2 days and am incredibly happy with the ease of use. I think a strong knowledge of Photoshop is required but if you have the PS skills you will be very happy with Sitegrinder.
For my full screen flash galleries I chose http://www.oxylusflash.com/flashfiles/amazing-fullscreen-panning-photo-gallery-as3
I like the user interface and the huge images that can be zoomed in and out along with navigation.
I certainly found customizing the code to these galleries challenging. Of coarse I am a photographer not a coder!
Since the full screen flash galleries take some time to load, do not work on smart phones yet, and may not be what potential customers are looking for I am also building HTML galleries through Bridge in PS CS 4.
For my VR galleries I chose http://www.immervision.com/en/multimedia/multimedia_technology.php
I really like the end user viewer and full screen ability as well as Pure's compression.
However I could not get Pure Tools to work on any of my Macs. They claim that the Mac software works. I did not get any replies to my emails or phone calls. Finally I dusted off my PC, fought with all the pop up and errors after I turned it on, crossed my fingers viruses did not eat its brain and loaded the Pure Tools on it. To my surprise it worked beautifully. I must say I really like the animated flairs that can be added to the VR's.
Other programs include:
Fetch
Dream Weaver
Photoshop CS4
Bridge CS4
My site should be ready to launch in about a week.
