For Raw Files and Beyond
Why We Need Them
The millions of microscopic sensors that collect light in our cameras’ photosensor arrays don’t actually record an image. Those sensors experience a bump in electric current when light hits them. The camera records the current passed along by every one of those millions of sensors. That doesn’t sound like an image, does it? It takes special software to interpret that electrical data and make pixels from it. So, Adobe has created that software.
