Multi-Spectral Imaging
I moved to the Mac Pro when my AMD dual-core WinXP system could not keep up with the file sizes. I shoot mulitple exposures through different UV-IR filters from 300-1000nm on a modified Canon 5D, convert them to B&W and stack them in Photoshop. To that stack, I add a visible light layer shot with a Canon 1Ds MkII. The 16-bit file sizes range from 300MB to nearly 1000mb.
I use PS CS3 Extended to auto-align the layers so I can drill down through them to see how each pixel reacts at different wavelengths. On the WinXP system, this process took 2-4 minutes depending on the number and complexity of layers. On the Mac Pro, it takes from 10 to 55 seconds.
The Mac Pro has 8GB RAM and 2TB of disk. It is network attached to 6TB of Buffalo TeraStation RAID-5 arrays, which are used for image backup, and an assortment of USB attached 250GB hard drives which were used for off-site backup. I moved the WinXP system off-site and it is now my off-site backup.
The computer is a tool, not a toy. I don't even own a video game. After working on it all day, and much of the night, playing games on it would be like a mechanic playing with his wrenches at home after working with them all day.
Same thing with my Jeep Rubicon. It gets me into the back country where I work and brings me out again. When you spend all day in low-range 4WD to get to the end of a 50+ mile Jeep trail, from where you backpack your equipment to shooting locations, you find quickly that four-wheeling ain't fun--It's work! While I have a very rough-country capable Jeep, I ain't no "Jeeper."
