How to Take the Picture
This is where you'll coordinate your movement to obtain the amount of intentional blur you desire.
After choosing your subject, you can begin at the bottom or top of the scene - experimenting with both ways.
The intent is to have a nice fluid camera motion from the top of the scene in a smooth downward movement to the bottom. It will take experimenting as you discover the optimum speed for camera movement and desired capture.
The starting shutter speed may be faster than needed or too slow. You can experiment with different speeds until you're happy with the results.
Check your ISO setting if necessary. If you have a challenge with the correct exposure and are in the manual camera mode, decrease the ISO if your photos are too bright or increase it if they're not quite bright enough - if you don't want to change the aperture or ISO.
If you discovered creating intentional blur in photography is fun, look out for opportunities to practice and grow your skills. Be reassured if things don't go as well as you'd envisioned, as it may feel awkward initially.
