Apple's Aperture workflow software is losing significant traction with professional photographers, claims Adobe. Citing data gathered by the research firm InfoTrends, Adobe notes that in a 2009 survey, only 12.5 percent of photographers with Macs reported using Aperture for RAW files; by contrast, Adobe's Lightroom software was nearly four times as popular, at 44.4 percent. The figures represent a widening gap, as in 2007, only 26.6 percent chose Lightroom and 14.3 percent chose Aperture.
