Calibrating The Color Of An iPad
I recently upgraded to the "new" Apple iPad. As I've mentioned before, it's a great tool for photographers. I love the high-resolution screen and faster processing speeds. But the exaggerated color rendered by the HD screen bothers me. I don't know if garish is the new normal, but I don't care for it because it gives my portfolio images a false, over-saturated look.

At a recent photo seminar, I saw Hector Martinez of Datacolor (makers of Spyders and other color-calibration tools) demonstrate how to view color-correct images on an iPad. There's an app for it, naturally. You start by downloading a free app from iTunes called SpyderGallery; the application creates a safe, color-calibrated space where you can view your image portfolios without unwanted enhancement.

The tricky part is that you do have to perform the color calibration yourself using one of Datacolor's Series 4 Spyders plugged into the USB of either a laptop or desktop computer. You place the Spyder on the iPad and start the app's setup. The iPad goes through a calibration process, showing the Spyder red, green and blue colors, and a series of gray tones. Once the calibration is completed, you use the SpyderGALLERY app on the iPad to display your portfolio with the correct colors. There's a slider at the bottom of the app's viewing screen that allows you to turn the corrected color off and on to see the difference, and it's significant. If you don't already have a Spyder, you should. It's very handy for its original purpose of calibrating your monitors so they display color accurately—something you should be doing on a regular basis if you're serious about photography.

Speed Up Your Laptop
If your laptop computer is sluggish or the hard drive is full, a potential answer is the new replacement solid-state hybrid drive from Seagate, the Momentus XT. I just changed out the drive in my MacBook Pro with the 750 GB version, and it sure beats replacing the whole laptop! The Momentus offers the fast access of solid state and the high capacity of a standard hard drive spinning at 7200 rpm, and it brings the laptop much closer to the capability of the desktop in handling large files in complex software programs, such as Photoshop and Lightroom. Get all the information about the Seagate Momentus XT at www.seagate.com.
