While digital photography has eliminated a number of filters, graduated neutral density filters are still considered irreplaceable -- but Sony is attempting a solution with software.

Sony’s latest software add-on is making HDR and graduated neutral density filters look a little old school.

Launched today, Digital Filter is an app for Sony cameras designed to mimic the effect of grads with a more advanced variation on the HDR technique, done automatically in-camera.

Sony says the app creates more accurate exposures by allowing the user to customize just what areas of the photograph to expose for.

Automated HDR, or High Dynamic Range, is typically shot using auto exposure bracketing, which takes a series of photos all at different exposure levels, with an equal change between each of the shots.

With PlayMemories Digital Filter, the camera instead allows the user to choose up to three areas in the image.
