Hello all,
What is your experience with ND filters? Any tips for aviation photography using ND filters?

Cheers,

Itay

My experience is not all that large, but I've used them on a few occasions, like shooting the annular solar eclipse and the transit of Venus last year.

I have an ND8 (3 stop) and an ND400 (between 8 and 9 stop) filter. The ND400 was invaluable for shooting the transit of Venus across the sun:



I haven't used them at all for aviation photography, though I have thought of using the ND8 for shots like this:



...so I don't have to stop down quite so much (that one was shot at F18, which makes cleaning up dust spots a huge hassle). But honestly, I just keep forgetting to try it.

One could also use an ND filter in aviation photography to achieve motion blur in broad daylight without closing down the aperture too much, but that's not something I'm particularly interested in.

Yeah - mostly to get very slow shutter speeds in bright light without using very small apertures.

Shooting at f22 or higher is problematic as a) it will show dust spots which are normally invisible and b) lens image quality tends to drop when shut right down.

ND filters solve the problem, but obviously its another layer of glass, so worth paying for quality, coated ones. Apart from that I can't think of anything 'special' to watch out for.

BTW - does anyone know why manufacturers can't offer us the option of low ISO settings (25 or 10)? I'd use these a lot more than some of the ridiculously high ISO ratings you can get these days.

Cheers,

No idea, but god that would be wonderful! I've taken a lot of shots where my aperture is squeezed down to F14+ because I can't go any lower than ISO100. They're usually long exposures, so I can't increase the shutter speed either....

Some full frame cameras (like 5D3/1DX) have extended ISO to 50, although even 500 wouldn't be much of a problem.
