Being able to use an electronic software filter program that allows you insert effects or control or change the image subsequent to it being captured provides a fantastic enhancement opportunity, but if you want to totally take control the decisive images you capture, no one has conceived a substitute for good old optical filters for precision and repetitive control of color balance or special effects in addition to the convenience.
When you filter the light prior to it getting to the lens and striking the sensor or the film plane, there are several important advantages. You are able to match the brightness extent of your subject to the traits of the medium you're capturing it to, and obtain results that are professional quality even when in tough lighting environments. As an example, polarizing filters eliminate reflections on glass, shiny, and water surfaces, although retaining sub-surface factors. These effects are not possible using software filters after the image is already captured, which can only impart filter effects, and not genuine light filtration.
Additionally elimination of uncertainty and ability to see the desired effect immediately, not hours or days later.
