thanks boweeb007!! Isaw it, but i thought it problem is only with RGB than reinhard is used

Well, that's true, too. But it also has to do with sky gain (turning it way up). I would've posted a little more text with the link, but it's such a common and confusing issue, for those new to indigo, that sometimes I'll just post the relevant link. Radiance is going to include a new tonemapping section in his tutorial to help clear things up.

Feel free to post more questions.
