hi
yesterday i bought an IR Filter 720nm , but i dont know how to get good-looking photos with this filter , i searched for some tutorials and tried to edit the photo as in the tutorials but it still not good.
i saw these photos for example , they r amazing , am not looking to get perfect photos like these , but at least something similar in the color :

Is your camera modified for IR?

In answer to your questions:

Color:
You say you purchased a filter, so I assume you have an unmodified camera. Two of the images you referenced are bordering on false-color infrared. You may not be able to achieve this with a filter (as opposed to modifying a camera), but with a red / blue channel swap in photoshop (tutorials all over the 'net) you might get close.

Drama:
Notice that the examples you give are all green plants and trees, and your images are all concrete and metal.

The most dramatic effects of IR photography can be seen in sky, water and plant life. Metal, concrete, asphalt and "city stuff" will produce much less drama, and in some subjects, you might not be able to tell it's IR at all.

To get more drama like in the examples, simply change your subject matter. Shoot landscapes of green plant life, water, and sky (especially partly cloudy situations containing both clouds and blue sky).

Hope that gets you started.

with the R72 filter you need to set a custom White Balance, then still apply PP. Swapping the red and blue channels is part of the process.

Here is one that I was able to process decently using the R72 filter.

Also I tried this once or twice.

Open the RAW files with DPP, use the WB tool and select foliage with the WB tool. That will give you the right White Balance. After that you need to swap the blue&red channels (artistic choice), just google infrared channel swap and you will find ways to do that on PS, Gimp or your favourite editing tool.

Shots look good!

Not much sense in editing a jpg, since the WB adjustments needs to be very severe.
Can you provide a raw?

As René pointed out, you'd do better with a Raw file for a starting point, but here's my take on your 3rd image do the fake colour IR channel swap treatment:

Hahahahaha manual, that's was too funny. No filters come with a manual, not even CPL filters. That was a good one.

Oh understandable. hehehe well do some research and you should find something helpful. IR filters are dense, so if you hold it up to the sun the sun should barely show and it will be a reddish color, now there a 9stop ND filter which is also dense but that will not show reddish. all other ND filter are see through.

For what it's worth...this is my first IR image...

The first image is with no PP, with out of the camera (convert to JPEG)...
The second image had the red and blue channels swapped, then some work to the saturation and tone...

Setting the white balance is critical... The suggestion of white balancing to the sunlit grass is KEY...
