Checking through the art filters on Olympus Pen E-P3, I haven’t been too impressed by most of them; yet the Dramatic Tone art filter can give outstanding results.
Experimenting with the art filter a little, I’ve found it can indeed make for dramatic images. Can emphasise contrasts; and can really emphasise design elements of photos.
Not always worthwhile, though; can make for messy greyish skies when there are blue skies originally. Also, I had a quick try with a rainbow, but thought the outcome was rather horrible.
Here are two photos from a situation when the dramatic tone filter worked really well (at the time of a ring of fire eclipse, though sun hidden by clouds!)
Below are images I’ve created using the Olympus dramatic tone effect.
