The Economic Times has an article about the future of digital cameras. According to the author of the article, Shelley Singh, future cameras will have a lot more than just higher pixel counts: better storage, picture management, better sensors, all weather protection, built-in GPS and so on. The author predicts that GPS will be a standard feature in DSLR, allowing the function of GeoTagging. These seem to make sense. However what is stated afterwards makes me wondering if the author knows what she is talking about.

“Next, today’s digital camera is just a documenting device working within the narrow bands of perception of our eyes. Tomorrow’s digital cameras could record temperature, infrared energy, and capture signals from wireless devices. We could use the camera as an aid to night vision too. Focus is another area that will see sharp improvements. That will help take care of the shooters dilemma: expose for the light parts of the scene and let the dark parts go black, or focus on the shadows and turn the bright parts sparkling white? Future sensors will fix this, with ever broader dynamic range and greater light sensitivity.”

Apparently the author was confused about focus and dynamic range. The author went to say this:

“Autofocus technology is set for great leaps too, ensuring that there won’t be any fuzziness in the picture, particularly in the background if you are taking a close-up of your two-year-old playing in the garden. Even the flowers will be in focus with an almost infinite depth of field, thanks to more digital processing.”

This is just funny. We often want some “fuzziness” in the background, so it is not too distracting. Perhaps it is possible in the future that “digital processing” will overcome the limits of current optical technology, but it is likely not “autofocus technology”.
