It’s slightly more defined, but still very soft.
Feathering
What we have seen is that hard grads, as well as soft grads have a degree of ‘feathering’ to them. The transition is gradual even for hard-grads.
This means that placement isn't so critical.
If you are finding your placement is bad, is more likely that you are using a grad that is too strong, rather than your problem being bad placement.
It also means that the grad isn't going to bite into mountains on the horizon so obviously, as the effect is too gradual to be noticed.
For those that do find their mountains are darkening down too much, I would suggest that it’s not the use of grads that is often the problem, it’s usually down to one of two things:
The wrong strength of grad is being applied (I’d say this is mostly the case)
The subject matter has very dark mountains and the grad has been placed a little too far down in the frame. Our eye tends to adjust and ‘not see’ the effect after a while, so when re-composing, always ‘wiggle’ the grad to see where it’s placed. Often times, it’s much lower than you intend it.
Conclusion
Firstly, grads don’t work the way we thought they do.
Hard grads are much softer than we think they are.
Placement is less critical, so long as we choose the right strength
Soft grads are very soft. I’d choose medium or hard grads over soft-grads for most of my work.
As you zoom in, grads become more diffused
As you zoom out, grads become more defined
With regards to point 4 and 5, I now own a set of Lee Filter medium grads alongside my Lee Filter hard grads (not all filter manufacturers make different degrees of gradation - hard, medium, soft). When I zoom in, I use the hard grads and when I zoom out, I use the medium grads. You may want to go one stage further and buy a set of very-hard grads. They will come into their own for focal lengths above 100mm.
6. Lastly, but most importantly, grads are more feathered than we assume. They don’t bite into the horizon as suddenly as we assume they do, and if you are finding so, then it’s most probably due to either the grad being too strong. Or it’s been placed too far down the frame. Wiggle it around to see where you’ve placed it. Often times our eyes adjust to the placement and we can’t see where the grad has been positioned. By wiggling it, we allow our eye to re-adjust to where the filter has been placed.
Finding out the right strength of filter
There are two ways to find the right strength of filter:
By trial and error (not recommended)
By learning to use your light meter and learning to read in f-stops
With point 2, I’ll reserve this for another blog posting.
