For years, pro photographers have used a gray card to enable them to accurately render color in photographs – now that time-honored tool has come to iPhone.
Pixelexip today announced GrayCard 1.0, their white balance tool for photographers. GrayCard puts a portable, adjustable gray card right in your pocket. It simulates various light temperatures and types on the iPhone or iPod Touch screen, and allows you to adjust your white balance to achieve different photographic effects in several easy steps.
GrayCard allows you to adjust your white balance to achieve different photographic effects in several easy steps:
1. Select how your scene is lit by choosing either Daylight/Flash or Tungsten (indoor lights, lamps and hotlights).
2. Easily warm or cool your photographs by selecting different white balances based on the light source being used. There are even minus green adjustments for correcting for fluorescent lighting.
3. Photograph your iPhone or iPod Touch in your scene displaying the desired white balance on the GrayCard application.
4. On your computer, use the white/gray balance eyedropper on the photo of your iPhone or iPod Touch. You have now taken control of the white balance in your photo.
