and yet, depth of field is a simple physical characteristic that you can see. For example, this is a crop from a photo with the
Mini 3 Pro. (The
Mini 3 does have a significantly faster lens than the
Air 2s at f1.7 vs f2.8 so about 1.5 stops faster.) The subject separation is more obvious if you were to shoot at 48Mp (more resolution) and focused on the something in the background like the tree. The problem with the
Mini 3 Pro of course is that you cannot turn this off; the aperture is fixed. For the
Air 2s with the slower f2.8, there would less subject separation if any.
For the
Mavic 3 with the same f2.8 and the m43, there would be more separation and it would be adjustable with the aperture. Usually, the application of changing the aperture on a drone would be to reduce light without having a crazy short shutter speed with the consequent negative effects.
You absolutely can use subject separation creatively with a drone. It is particularly interesting when combined with the ability to subject focus from the touch screen.
BTW, the crop makes if appear I am closer to the lamp than I really am. Rather than think too hard about it, give it a try. It's one more tool to express creativity.
Good Luck!
