Ronja, what a great use of ICM! My first thought in seeing it is that it reminds me of what itās like looking through the windshield of the car when youāre driving in heavy snowā¦ the way the snow rush deflects on all sides. Very cool!
I personally think the 1/20" was a great choice (even if your choices were limited because of not having a filter). I find with ICM, the faster the shutter speed (up to 1/30"), the more detail is possibleā¦ if there are strong lines in the scene, it gives some edge to those lines while blurring the rest. One key with ICM at faster speeds is to start moving (smooth and quick!) your camera/lens before you press the shutter. If you wait to move until you click, youāll just get blur, not ICM.
Iāve done ICMs as fast as 1/80", even some at 1/100"! That said, most of mine are in the .8"-1/30" range, with highest concentration between .8" - 1" range. My ICM subjects are nature, architecture, and still life (including slinkies, curled pieces of paper, cut lettuceā¦ limitless possibilities!).
You might also already know this, but if you want a slower shutter speed w/out a filter, increase your aperture as much you need to balance out a slower shutter. Usually I need to set mine to at least f/11 to compensate for the more open shutter. Just be aware that if your sensor has any spots, the smaller the aperture, the more those spots will show up when you go to process!
Anyway, you didnāt ask for an ICM lesson so offering in the spirit of your request for ideas on the technique.
I agree with others somewhat on the need to have a central focal point in an image like this. It doesnāt bother me in this case, as there is a small clump of snow that anchors the middle. The challenge might be that itās not quite defined enough to really be a focus, and therefore it lacks intentionality. But I see this as a very successful ICM and love the combo of motion and definition youāve achieved!
If youāre not already part of it, I highly recommend the active and supportive ICM Photo Mag community on Facebook. Information and inspiration galore!!
Looking forward to seeing more of your work as you keep diving into the ICM waters!
