what is the correct order to attach different filters?

If I want to use a 10 stop ND filter,a 3 stop ND grad filter and a polarising filter all together,what is the correct order to attach them.Which one has to be on top and which one has to be at the bottom?

The polarizer needs to be the one in the front-most position so that it can be adjusted; the rest can be in any order. With that many filters, you are going to have to set up your shot in LiveView so that you can see your composition.

I've never needed anything more than 10-stops; you are looking at shooting with the equivilent of around 15 stops. Are you sure you need that much light stopping power? Three filters stacked on even a moderately wide angle lens are going to cause vignetting.

I have seen some videos to shoot waterfalls and the man has used both a 10 stop nd filter and a polarising filter,that's why I want to know if there is a certain order to use them together..Don't you think it is a good idea to use a 3 stop nd grad with a 10 stop nd to cover the exposure diffrence between sky and land?If I use only a 10 grad nd ,land gets darker because of the exposure difference...

I've never had to use a 10-stop filter, a3-stop ND grad, and a polarizer for the same shot. I usually attach my polarizer when I'm doing landscape shots without any other filters. As for the 3-stop ND grad, I use it to darken the sky and even out the exposure of the foreground and background. Occasionally I also use it wih my Big Stopper because it results in a much better effect than adding a grad filter in post. I do agree stacking all three filters would prolong the exposure, cause unwanted colour casts, and horrible vignetting if you're using a wide angle lens. The correct order of stacking all three lenses would be the 10-stop closest to your lens, the the ND grad, and finally the CPL, but if you're using Lee filters rather than screw-ons then be prepared to pay a lot, especially for the CPL.

Generally, I prefer using the fewest filters at all possible. I have not experimented with using a three-stop + a ten-stop + a polarizer. I am wondering if all that glass might not cause problems with flare and/or vignetting. However, if I were experimenting with three filters, I would place the polarizer in front. However, that is the fun of experimenting in the wonderful world of shooting digital in which extra experimental exposures don't cost any money...

I would definitely want to use a sun shade with the above combination to prevent as much flare as possible. One problem might be is that the three filters could stick out far enough so that the value of lens sun shade might be negated. This, of course, depends on the type of sunshade you are using...

Here is a possible, low cost solution which would require the purchase of a linear polarizing filter. Linear polarizers are usually quite inexpensive since they are seldom used with today's cameras...

I have to admit that I have been lax in attempting this. I purchased a linear polarizer, for a couple of U.S. dollars a while ago, at a photography rummage sale but, never seem to remember to bring it with me when I go out to shoot a scene which would benefit from the long exposures

When I do, I hope that I will remember to shoot a white balance target since the color balance of this filter combination seems to lean towards the green...

finally the CPL, but if you're using Lee filters rather than screw-ons then be prepared to pay a lot, especially for the CPL.

No need to pay the extra money for the Lee name; the Sigma 105mm had the same specs as the Lee for about half the price (this is what I use with the Lee holder); both are uncoated designs. Hitech and Lee are about the same cost while the Formatt is a bit less expensive. If you want a coated filter in this size; these make the Lee option look inexpensive.
