jsf Posted October 13, 2006 Share Posted October 13, 2006 The image is underexposed. You can change your shutter speed and ISO while the image is rendering. Change one at a time, then both. Once you have done this you can make a determination about whether to change your exposure by adjusting the camera's f-stop setting, adjusting the shutter speed, the ISO, or a combination of the three. A small f-stop number of 2, for example, will increase depth of field (DOF) making the image look toy like. An ISO of 800, for example, corresponds with a faster film type which is good for indoor shots but may increase grain which in Maxwell Render is not always a good thing. You can easily find info on apeture and shutter speed settings online. Link to comment Share on other sites More sharing options...
AJLynn Posted October 13, 2006 Share Posted October 13, 2006 It's one of three things: materials too dar, or lights too low, or incorrect camera settings. Try the materials in MXED and see how they look in preview, then make sure the emitter output is reasonable, then check you camera - for an interior like this it wouldn't be unreasonable to be up into F5.6/ISO400/Shutter 1/125 or slower.

thickly Posted October 13, 2006 Share Posted October 13, 2006 I have found that I usually have to use very high emitter watts to get the light levels up (5,000w, 10,000w). Dropping the shutter speed will definitely help a lot. I have also been cheating a lot lately by using invisible emitters to get adequate light levels, especially with interior shots. There is an Invisible Emitter tutorial on the Maxwell forum in the Tuts section -- its very easy. Also, enable multi-light, that way you can boost light output while it is rendering and afterwards also. Link to comment Share on other sites More sharing options...
shangriladida Posted October 14, 2006 Author Share Posted October 14, 2006 ooo..ic i havent checked them(ur suggested solutions) yet. But, it shud be helpful getting those tips from u guys. Thanks alot! about the invisible emitter...Does it really exist? I thought MR is about real lights, when u set ur light in there, it shud appear or give a real world result... Im not sure about my materials though. Coz in sketchup, the materials used are quite bright. i even edited them in photoshop. But I dont know that adjusting shutter speed and f stop thing could give something! about f stop..why cannot adjust? ive looked at them after render..its disabled. Guess I hafta check during render... Anyway, thanks! -sham- Link to comment Share on other sites More sharing options...

Anyway, thanks! -sham- F stop can't be adjusted while you are rendering, in order for you to be able to adjust all of your settings you must save out an MXI file and then load it. Once you do this you can adjust all of the settings, while you are rendering you can only adjust shutter speed and ISO. Link to comment Share on other sites More sharing options...
