    Digital filters - fun or folly?

    I just did these shots today to at least see what digital filters in the K20D can do - or not do. These only work on jpg's, and I shoot RAW, so this is pretty much a one-time thing :-) And, you can do nearly the same thing is PP software. Anyway, it might be interesting to some.

    B&W (there are other varieties I will show on another image later).

    Adding color. There are color choices, and 3 strength options. This is overdoing magenta (I think) on heaviest. Makes it look like a fading 50's photo, sort of.

    Color extract - blue. Selectable color to keep, everything else goes BW.

    HDR. This also has 3 strengths (heaviest here) and probably not the right image for it.

    Sepia. A common PP option in software, here applied on heavy.

    Soft focus. Again, this is heaviest, and not the best image for it. Flowers may be better.

    I did not use the "slim" filter which allows you to alter the aspect ratio.

    Hmm... As you say... interesting to play with but I never was a fan of filters even in the film days.

    I used to use (back in my 35mm days) the following filters:
    Star 8
    ND
    Orange
    Red
    Yellow
    Green
    Polariser

    I tried all the other kinds of filters and was never impressed. Look at the photos that sell... Not a single bizarre filter amongst them. Mostly ND or polariser. No starbursts. No funky coloured grads... Just plain photos. Soft Focus could be useful for portraits though.

    digital filters just feel cheap..

    I agree with ND/Polariser being the most "effective"

    I've seen some amazing colour grad filter shots however..



    to me, curves is my bread and butter..
