A while ago one of our number experienced a ghost image in one of his *istD shots, and asked what it might be. It looked like a classic type of ghost image that has been known since the beginning of photography, but some folks here were adamant that it was caused by reflection from the sensor. Of course it was possible that it WAS from the sensor, but why look for a more complex explanation when a simpler explanation - that the ghost image came entirely from the lens or filter - already had a history as the source of ghosting flare. The photographer in question soon proved that an uncoated filter was the cause of the problem by reproducing the ghost images deliberately, and then noting the absence of ghost-imaging when the filter was removed. The 'It's The Sensor's Fault' chorus fell suddenly silent.
My feeling is that 'Digital Problems' are more likely to be some of the less common occurences of camera-work that are being experienced due to the sheer volume of shots being taken by new digital photographers. The laws of probability are simply catching up on them. Admittedly, a shiny sensor can be the source of ghost images or scattering flare, but those problems can only follow through to completion if the stray light encounters substandard baffling in the mirror-box, or substandard coating on optical surfaces. We Pentax users have long been well served on the last point, but it seems that time and progress has caught up on some Other Brands who have been content to apply the lens coatings of their accountants' choice. regards, Anthony Farr ----- Original Message ----- From: "John Forbes" <[EMAIL PROTECTED]> > Have any digital slr users experienced the sensor-reflection phenomenon > referred to by Keppler? > > It's a bit worrying.
