Having sold laptops for almost 20 years, I would suggest the following:
- 16GB Ram
- separate graphics processor with 4GB Ram (not shared system ram)
- memory based hard drive (much faster, more reliable)
- 15.6 inch screen (highest resolution possible in your budget)
- HDMI port for external flat screen when not going mobile
- Intel i7 core processor (again if it fits the budget)
Brands (order of recommendation):
- Panasonic Toughbook 54 series (pricey but extremely reliable)
- ACER (several different models)
- Lenovo

You will notice I didn't include DELL or HP, that's because they don't make their own
laptops, they are manufactured in Taiwan by a third party and then assembled here
in the U.S. (This can cause quality control/reliability issues).

Hope this is helpful.

Several weeks ago, I solicited advice on how to shoot the Albuquerque Balloon Fiesta, a yearly event which is the largest hot air balloon gathering in the World. I received some useful advice and thought I would share a few of the shots from the event. It begins in total darkness. The balloons are illuminated solely by their propane flames, requiring very high ISO's. I mostly shot at 6400, and after studying them on my computer, I concluded I probably should have shot even higher. I couldn't see the controls on my camera and my fingers were so cold I couldn't feel them.

This is a great event for photographers and will challenge your abilities. Suggestions for improving the pictures are welcome.
