    You changed the order of the photos,thank you,I found out that the order had to be different but changing the order might be helpful for other people.-)

    Binnur - Not necessarily true; I have the Lee grads / holder (including a 105mm CPol) and a B+W 10-stop ND. There is nothing to stop me from using the ND and either hand-holding the Lee grad in front of the ND or screwing the Lee filter holder into the B+W ND and mounting the grad(s) into the Lee holder. Seeing as you already own the B+W 10-stop filter you have a perfectly workable solution already. If you want to go out and buy the Lee Big Stopper, you certainly can. Putting three filters (1-Big Stopper, 1- 3-stop hard grad, one CPol) in the Lee holder is going to give you a higher risk of vignetting at wider angles. The screw in B+W is going to give you a slightly better profile.

    Colin was suggesting that the screw in grad is what he threw out, because one cannot adjust the composition of the shot based on where the gradient starts on the filter. I shoot in rainy / snowy conditions and find that I can keep my circular Heliopan grad out of the rain, but the Lee filters are so large and awkward, that I can't.

    Off memory, I think the Big Stopper imparts a pretty nasty colourcast. I believe that Singh-Ray have recently introduced a 10 stop moreslo that's much better.

    The Lee is pretty colour cast neutral.

    If you're going to be using ND Grads the square/rectangular drop in are far and away your best option.

    The circular ND grad was straight a cross he middle of the lens, giving you no control over where your graduation would start. Then if you screw in a 100 stop you risk the grad moving. While you screw the 10 stop in and can't. See until after the long exposure is taken.

    Literally a waste of time

    Re: is it useful to use an nd grad filter with a 10 stop nd filter?

    I can't say I agree with you on this one, Phil. Here is the setup I suggested to Binnur with a mix of Lee and his 10-stop B+W ND.

    Image 1:

    - 105mm Sigma Cpol
    - Lee Holder with 77mm WA adaptor
    - 3-stop hard grad Lee filter
    - 10-stop B+W ND filter (77mm)

    is it useful to use an nd grad filter with a 10 stop nd filter?




    Image 2:


    Equipment mounted on camera. The 77mm B+W 10-stop ND attached to f/2.8 24-70 Nikkor filter threads. A Lee WA adaptor ring hold the Lee holder with the 3-stop ND, screwed into the 10-stop ND. The Sigma 105mm polarizer is at the front.

    is it useful to use an nd grad filter with a 10 stop nd filter?


    Using the viewfinder to set up the shot is tricky; as the 10-stop filter nicely blocks out virtually all light, but LiveView works just fine and does a reasonable job showing the composition.

    That doesn't seem to disagree with my comments at all......

    Re: is it useful to use an nd grad filter with a 10 stop nd filter?

    I was able to set up as similar approach using three 77mm filters.

    Again, the 10-stop B+W ND goes against the lens; then the 77mm B+W polarizer (prealigned using LiveView) before screwing in the then the 77mm Heliopan grad. All three filters are brass mount filters so they are easier to get apart, A bit of gaffer tape will keep the polarizer from rotating while mounting the grad. The front element of the grad still turns.

    Not as easy as with the Lee setup, but it can still be done. Leave off the polarizer and it is actually quite easy using LiveView.

    Re: is it useful to use an nd grad filter with a 10 stop nd filter?

    Ok Binnur listen as you have a screw in B+W 10 stop filter and you want to add a 3 stop simply use 10 stop than in post use GND tool to add and extra 3 stops to the sky, most people who use a 10 stop want real long exposures 3 to 10 minutes in length. If you want more control using ND and GND than you need to use a filter holder so you can stack filters I have done this however just using the GND tool in ACR works better as I can adjust the number of stops, if added your way I could blow the image completely and not recover it your choice.

    Unfortunately ...

    That approach increases the noise about 8 fold, and reduces the exposure (length) by the same about as doing it digitally doesn't compress the dynamic range of the scene at the time, thus you have to expose for the (brighter) highlights (say, 3 stops brighter).

    If you're going to do it digitally (assuming a 3-stop reduction) you need to take 8 consecutive shots and then stack them before applying the digital GND (which incidentally is probably a better way to do it; past a certain point with WA and especially UWA lenses stacking filters turns vignetting into outright obstruction).

    Re: is it useful to use an nd grad filter with a 10 stop nd filter?

    what about buying a screw-in nd grad and using it with my screw-in 10 stop B+W nd?Does it cause vignetting?

    That depends on the lens; a wide angle shot will likely cause vignetting, while a longer shot is less likely to. It really depends on the lens and filter design. Using a polarizer and round grad can be done, but is a pain to do. Why do you think I spent the money on the Lee system? That is one of the reasons.

    But I won't be able to adjust grad nd properly, because it is screw-in,will I?.Same problem as Colin had:-(If I go and buy a lee filter holder and rectengular nd grad,it is a solution as you said,but if I want to take more than one shot at sunset,it is going to be difficult to take 10 stop nd off each time to set my new position.I might aswell go like this in the beginning till I have enough of the situation and then buy a bigstopper.I can't see any other way.Thanks for the brainstorming:-)

    Re: is it useful to use an nd grad filter with a 10 stop nd filter?

    As everyone has said; screw-in grads are not a great solution, but if that is all you have, then there are work-arounds.

    A 10-stop ND is hard to work with through the viewfinder; with 1/1000th of the light getting through, it really means you are shooting blind. If you use one and you want to shoot this way, you have to remove it for every shot to compose.

    I have found that using LiveView is a good work around as you do get around this problem fairly well, so I tend to use this solution where I can. I haven't tried if for sunset shots, so I'm can't give you specific recommendations there. It has worked for me with daylight shots, but with the reduced light levels at sunset, I don't know...

    Sorry about not noticing your other messages above,I will get used to this system in time I suppose..I read all your explanations and found out that if I use live view mode there wouldn't be any problem to set my new compositions.so I can go and buy a lee filter holder and a rectengular 3 nd grad :-)Thanks again for your help.

    At sunset shots as well,I will give it a go..if it doesn't work ,I can think about it later:-)thanks.

    Another reason to use a Singh-Ray Vari-ND; you just drop the attenuation with a twist - recompose - and then whack it back up again

    Re: is it useful to use an nd grad filter with a 10 stop nd filter?

    Colin,is it possible to use different brands of filters in the same filter holder?Let's say,I have a lee filter holder,can I use other brands of filters,for instance Singh-Ray or they don't fit each other...

    Re: is it useful to use an nd grad filter with a 10 stop nd filter?

    The thickness of the filter will be designed for the filter holder from the same manufacturer. You might find some will work together, but certainly not all.

    (As I use only Lee, I can't really comment on the other brands).
